A ``#`` +marker anywhere else in the line will be treated as an argument. This +allows statements like: + +:: + + # Comment + RUN echo 'we are running some # of cool things' + +.. _dockerfile_instructions: + +3. Instructions +=============== + +Here is the set of instructions you can use in a ``Dockerfile`` for +building images. + +.. _dockerfile_from: + +3.1 FROM +-------- + + ``FROM `` + +Or + + ``FROM :`` + +The ``FROM`` instruction sets the :ref:`base_image_def` for subsequent +instructions. As such, a valid Dockerfile must have ``FROM`` as its +first instruction. The image can be any valid image -- it is +especially easy to start by **pulling an image** from the +:ref:`using_public_repositories`. + +``FROM`` must be the first non-comment instruction in the +``Dockerfile``. + +``FROM`` can appear multiple times within a single Dockerfile in order +to create multiple images. Simply make a note of the last image id +output by the commit before each new ``FROM`` command. + +If no ``tag`` is given to the ``FROM`` instruction, ``latest`` is +assumed. If the used tag does not exist, an error will be returned. + +.. _dockerfile_maintainer: + +3.2 MAINTAINER +-------------- + + ``MAINTAINER `` + +The ``MAINTAINER`` instruction allows you to set the *Author* field of +the generated images. + +.. _dockerfile_run: + +3.3 RUN +------- + + ``RUN `` + +The ``RUN`` instruction will execute any commands on the current image +and commit the results. The resulting committed image will be used for +the next step in the Dockerfile. + +Layering ``RUN`` instructions and generating commits conforms to the +core concepts of Docker where commits are cheap and containers can be +created from any point in an image's history, much like source +control. + +Known Issues (RUN) +.................. + +* :issue:`783` is about file permissions problems that can occur when + using the AUFS file system. You might notice it during an attempt to + ``rm`` a file, for example. The issue describes a workaround. +* :issue:`2424` Locale will not be set automatically. + +.. _dockerfile_cmd: + +3.4 CMD +------- + +CMD has three forms: + +* ``CMD ["executable","param1","param2"]`` (like an *exec*, preferred form) +* ``CMD ["param1","param2"]`` (as *default parameters to ENTRYPOINT*) +* ``CMD command param1 param2`` (as a *shell*) + +There can only be one CMD in a Dockerfile. If you list more than one +CMD then only the last CMD will take effect. + +**The main purpose of a CMD is to provide defaults for an executing +container.** These defaults can include an executable, or they can +omit the executable, in which case you must specify an ENTRYPOINT as +well. + +When used in the shell or exec formats, the ``CMD`` instruction sets +the command to be executed when running the image. This is +functionally equivalent to running ``docker commit -run '{"Cmd": +}'`` outside the builder. + +If you use the *shell* form of the CMD, then the ```` will +execute in ``/bin/sh -c``: + +.. code-block:: bash + + FROM ubuntu + CMD echo "This is a test." | wc - + +If you want to **run your** ```` **without a shell** then you +must express the command as a JSON array and give the full path to the +executable. **This array form is the preferred format of CMD.** Any +additional parameters must be individually expressed as strings in the +array: + +.. code-block:: bash + + FROM ubuntu + CMD ["/usr/bin/wc","--help"] + +If you would like your container to run the same executable every +time, then you should consider using ``ENTRYPOINT`` in combination +with ``CMD``. See :ref:`dockerfile_entrypoint`. + +If the user specifies arguments to ``docker run`` then they will +override the default specified in CMD. + +.. note:: + Don't confuse ``RUN`` with ``CMD``. ``RUN`` actually runs a + command and commits the result; ``CMD`` does not execute anything at + build time, but specifies the intended command for the image. + +.. _dockerfile_expose: + +3.5 EXPOSE +---------- + + ``EXPOSE [...]`` + +The ``EXPOSE`` instruction exposes ports for use within links. This is +functionally equivalent to running ``docker commit -run '{"PortSpecs": +["", ""]}'`` outside the builder. Refer to +:ref:`port_redirection` for detailed information. + +.. _dockerfile_env: + +3.6 ENV +------- + + ``ENV `` + +The ``ENV`` instruction sets the environment variable ```` to the +value ````. This value will be passed to all future ``RUN`` +instructions. This is functionally equivalent to prefixing the command +with ``=`` + +.. note:: + The environment variables will persist when a container is run + from the resulting image. + +.. _dockerfile_add: + +3.7 ADD +------- + + ``ADD `` + +The ``ADD`` instruction will copy new files from and add them to +the container's filesystem at path ````. + +```` must be the path to a file or directory relative to the +source directory being built (also called the *context* of the build) or +a remote file URL. + +```` is the path at which the source will be copied in the +destination container. + +All new files and directories are created with mode 0755, uid and gid +0. + +.. note:: + if you build using STDIN (``docker build - < somefile``), there is no build + context, so the Dockerfile can only contain an URL based ADD statement. + +.. note:: + if your URL files are protected using authentication, you will need to use + an ``RUN wget`` , ``RUN curl`` or other tool from within the container as + ADD does not support authentication. + +The copy obeys the following rules: + +* The ```` path must be inside the *context* of the build; you cannot + ``ADD ../something /something``, because the first step of a + ``docker build`` is to send the context directory (and subdirectories) to + the docker daemon. +* If ```` is a URL and ```` does not end with a trailing slash, + then a file is downloaded from the URL and copied to ````. +* If ```` is a URL and ```` does end with a trailing slash, + then the filename is inferred from the URL and the file is downloaded to + ``/``. For instance, ``ADD http://example.com/foobar /`` + would create the file ``/foobar``. The URL must have a nontrivial path + so that an appropriate filename can be discovered in this case + (``http://example.com`` will not work). +* If ```` is a directory, the entire directory is copied, + including filesystem metadata. +* If ```` is a *local* tar archive in a recognized compression + format (identity, gzip, bzip2 or xz) then it is unpacked as a + directory. Resources from *remote* URLs are **not** decompressed. + + When a directory is copied or unpacked, it has the same behavior as + ``tar -x``: the result is the union of + + 1. whatever existed at the destination path and + 2. the contents of the source tree, + + with conflicts resolved in favor of "2." on a file-by-file basis. + +* If ```` is any other kind of file, it is copied individually + along with its metadata. In this case, if ```` ends with a + trailing slash ``/``, it will be considered a directory and the + contents of ```` will be written at ``/base()``. +* If ```` does not end with a trailing slash, it will be + considered a regular file and the contents of ```` will be + written at ````. +* If ```` doesn't exist, it is created along with all missing + directories in its path. + +.. _dockerfile_entrypoint: + +3.8 ENTRYPOINT +-------------- + +ENTRYPOINT has two forms: + +* ``ENTRYPOINT ["executable", "param1", "param2"]`` (like an *exec*, + preferred form) +* ``ENTRYPOINT command param1 param2`` (as a *shell*) + +There can only be one ``ENTRYPOINT`` in a Dockerfile. If you have more +than one ``ENTRYPOINT``, then only the last one in the Dockerfile will +have an effect. + +An ``ENTRYPOINT`` helps you to configure a container that you can run +as an executable. That is, when you specify an ``ENTRYPOINT``, then +the whole container runs as if it was just that executable. + +The ``ENTRYPOINT`` instruction adds an entry command that will **not** +be overwritten when arguments are passed to ``docker run``, unlike the +behavior of ``CMD``. This allows arguments to be passed to the +entrypoint. i.e. ``docker run -d`` will pass the "-d" +argument to the ENTRYPOINT. + +You can specify parameters either in the ENTRYPOINT JSON array (as in +"like an exec" above), or by using a CMD statement. Parameters in the +ENTRYPOINT will not be overridden by the ``docker run`` arguments, but +parameters specified via CMD will be overridden by ``docker run`` +arguments. + +Like a ``CMD``, you can specify a plain string for the ENTRYPOINT and +it will execute in ``/bin/sh -c``: + +.. code-block:: bash + + FROM ubuntu + ENTRYPOINT wc -l - + +For example, that Dockerfile's image will *always* take stdin as input +("-") and print the number of lines ("-l"). If you wanted to make +this optional but default, you could use a CMD: + +.. code-block:: bash + + FROM ubuntu + CMD ["-l", "-"] + ENTRYPOINT ["/usr/bin/wc"] + +.. _dockerfile_volume: + +3.9 VOLUME +---------- + + ``VOLUME ["/data"]`` + +The ``VOLUME`` instruction will create a mount point with the specified name and mark it +as holding externally mounted volumes from native host or other containers. For more information/examples +and mounting instructions via docker client, refer to :ref:`volume_def` documentation. + +.. _dockerfile_user: + +3.10 USER +--------- + + ``USER daemon`` + +The ``USER`` instruction sets the username or UID to use when running +the image. + +.. _dockerfile_workdir: + +3.11 WORKDIR +------------ + + ``WORKDIR /path/to/workdir`` + +The ``WORKDIR`` instruction sets the working directory in which +the command given by ``CMD`` is executed. + +.. _dockerfile_examples: + +4.

The +``cidfile`` flag makes Docker attempt to create a new file and write the +container ID to it. If the file exists already, Docker will return an +error. Docker will close this file when ``docker run`` exits. + +.. code-block:: bash + + $ sudo docker run -t -i -rm ubuntu bash + root@bc338942ef20:/# mount -t tmpfs none /mnt + mount: permission denied + + +This will *not* work, because by default, most potentially dangerous +kernel capabilities are dropped; including ``cap_sys_admin`` (which is +required to mount filesystems).

In other words, the container can then do almost +everything that the host can do. This flag exists to allow special +use-cases, like running Docker within Docker. + +.. code-block:: bash + + $ sudo docker run -w /path/to/dir/ -i -t ubuntu pwd + +The ``-w`` lets the command being executed inside directory given, +here ``/path/to/dir/``. If the path does not exists it is created inside the +container. + +.. code-block:: bash + + $ sudo docker run -v `pwd`:`pwd` -w `pwd` -i -t ubuntu pwd + +The ``-v`` flag mounts the current working directory into the container. +The ``-w`` lets the command being executed inside the current +working directory, by changing into the directory to the value +returned by ``pwd``. So this combination executes the command +using the container, but inside the current working directory. + +.. code-block:: bash + + $ sudo docker run -p 127.0.0.1:80:8080 ubuntu bash + +This binds port ``8080`` of the container to port ``80`` on ``127.0.0.1`` of the +host machine. :ref:`port_redirection` explains in detail how to manipulate ports +in Docker. + +.. code-block:: bash + + $ sudo docker run -expose 80 ubuntu bash + +This exposes port ``80`` of the container for use within a link without +publishing the port to the host system's interfaces. :ref:`port_redirection` +explains in detail how to manipulate ports in Docker. + +.. code-block:: bash + + $ sudo docker run -name console -t -i ubuntu bash + +This will create and run a new container with the container name +being ``console``. + +.. code-block:: bash + + $ sudo docker run -link /redis:redis -name console ubuntu bash + +The ``-link`` flag will link the container named ``/redis`` into the +newly created container with the alias ``redis``. The new container +can access the network and environment of the redis container via +environment variables. The ``-name`` flag will assign the name ``console`` +to the newly created container. + +.. code-block:: bash + + $ sudo docker run -volumes-from 777f7dc92da7,ba8c0c54f0f2:ro -i -t ubuntu pwd + +The ``-volumes-from`` flag mounts all the defined volumes from the +referenced containers. Containers can be specified by a comma seperated +list or by repetitions of the ``-volumes-from`` argument. The container +ID may be optionally suffixed with ``:ro`` or ``:rw`` to mount the volumes in +read-only or read-write mode, respectively. By default, the volumes are mounted +in the same mode (read write or read only) as the reference container. + +A complete example +.................. + +.. code-block:: bash + + $ sudo docker run -d -name static static-web-files sh + $ sudo docker run -d -expose=8098 -name riak riakserver + $ sudo docker run -d -m 100m -e DEVELOPMENT=1 -e BRANCH=example-code -v $(pwd):/app/bin:ro -name app appserver + $ sudo docker run -d -p 1443:443 -dns=dns.dev.org -v /var/log/httpd -volumes-from static -link riak -link app -h www.sven.dev.org -name web webserver + $ sudo docker run -t -i -rm -volumes-from web -w /var/log/httpd busybox tail -f access.log + +This example shows 5 containers that might be set up to test a web application change: + +1. Start a pre-prepared volume image ``static-web-files`` (in the background) that has CSS, image and static HTML in it, (with a ``VOLUME`` instruction in the ``Dockerfile`` to allow the web server to use those files); +2. Start a pre-prepared ``riakserver`` image, give the container name ``riak`` and expose port ``8098`` to any containers that link to it; +3. Start the ``appserver`` image, restricting its memory usage to 100MB, setting two environment variables ``DEVELOPMENT`` and ``BRANCH`` and bind-mounting the current directory (``$(pwd)``) in the container in read-only mode as ``/app/bin``; +4. Start the ``webserver``, mapping port ``443`` in the container to port ``1443`` on the Docker server, setting the DNS server to ``dns.dev.org``, creating a volume to put the log files into (so we can access it from another container), then importing the files from the volume exposed by the ``static`` container, and linking to all exposed ports from ``riak`` and ``app``. Lastly, we set the hostname to ``web.sven.dev.org`` so its consistent with the pre-generated SSL certificate; +5. Finally, we create a container that runs ``tail -f access.log`` using the logs volume from the ``web`` container, setting the workdir to ``/var/log/httpd``. The ``-rm`` option means that when the container exits, the container's layer is removed. + + +.. _cli_save: + +``save`` +--------- + +:: + + Usage: docker save image > repository.tar + + Streams a

We still have a few of these cases, but they're reduced to a minimum now.

We'll go through what the +developer might have set in each Dockerfile instruction and how the +operator can override that setting. + + +CMD +... + +Remember the optional ``COMMAND`` in the Docker commandline:: + + docker run [OPTIONS] IMAGE[:TAG] [COMMAND] [ARG...] + +This command is optional because the person who created the ``IMAGE`` +may have already provided a default ``COMMAND`` using the Dockerfile +``CMD``. As the operator (the person running a container from the +image), you can override that ``CMD`` just by specifying a new +``COMMAND``. + +If the image also specifies an ``ENTRYPOINT`` then the ``CMD`` or +``COMMAND`` get appended as arguments to the ``ENTRYPOINT``. + + +ENTRYPOINT +.......... + +:: + + -entrypoint="": Overwrite the default entrypoint set by the image + +The ENTRYPOINT of an image is similar to a COMMAND because it +specifies what executable to run when the container starts, but it is +(purposely) more difficult to override. The ENTRYPOINT gives a +container its default nature or behavior, so that when you set an +ENTRYPOINT you can run the container *as if it were that binary*, +complete with default options, and you can pass in more options via +the COMMAND. But, sometimes an operator may want to run something else +inside the container, so you can override the default ENTRYPOINT at +runtime by using a string to specify the new ENTRYPOINT.

You could simply provide application developers +with a boilerplate Dockerfile to copy-paste into their application, but that is +inefficient, error-prone and difficult to update because it mixes with +application-specific code. + +The solution is to use *ONBUILD* to register in advance instructions to run later, +during the next build stage. + +Here's how it works: + +1. When it encounters an *ONBUILD* instruction, the builder adds a trigger to + the metadata of the image being built. + The instruction does not otherwise affect the current build. + +2.

The option continues to work. Note that an alternative to 'commit --run' is being implemented but is not yet available. We are printing the warning anyway because on the basis that it never hurts to give more advance warning. The 'commit --run' flag is a leftover from the very early days of Docker, and has several problems: 1) It is very user unfriendly. You have to pass a literal json dict which is poorly documented and changes regularly (see PortSpecs vs ExposedPorts). The merge behavior is not clear and also changes regularly. it's not possible to unset a value. 2) It overlaps with the Dockerfile syntax. There are 2 ways to set a default command, expose a port or change an env variable. Some things can be done in a Dockerfile but not in --run. Some things can be done in --run but not in a Dockerfile. It would be better to push a single syntax, allow using it both in a file and via the command line, and make improvements in a single place. 3) It exposes data structures which should not be publicly exposed. There are several planned improvements to Docker which require moving around the content and schema of the various Config, Image and Container structures. The less of those we expose in public interfaces, the easier it is to move things around without a reverse compatibility nightmare.

If the +used tag does not exist, an error will be returned. + +## `MAINTAINER` + +> `MAINTAINER ` + +The `MAINTAINER` instruction allows you to set the +*Author* field of the generated images. + +## `RUN` + +RUN has 2 forms: + +- `RUN ` (the command is run in a shell - + `/bin/sh -c`) +- `RUN ["executable", "param1", "param2"]` (*exec* + form) + +The `RUN` instruction will execute any commands in a +new layer on top of the current image and commit the results. The +resulting committed image will be used for the next step in the +Dockerfile. + +Layering `RUN` instructions and generating commits +conforms to the core concepts of Docker where commits are cheap and +containers can be created from any point in an image’s history, much +like source control. + +The *exec* form makes it possible to avoid shell string munging, and to +`RUN` commands using a base image that does not +contain `/bin/sh`. + +### Known Issues (RUN) + +- [Issue 783](https://github.com/dotcloud/docker/issues/783) is about + file permissions problems that can occur when using the AUFS file + system. You might notice it during an attempt to `rm` + a file, for example. The issue describes a workaround. +- [Issue 2424](https://github.com/dotcloud/docker/issues/2424) Locale + will not be set automatically. + +## `CMD` + +CMD has three forms: + +- `CMD ["executable","param1","param2"]` (like an + *exec*, preferred form) +- `CMD ["param1","param2"]` (as *default + parameters to ENTRYPOINT*) +- `CMD command param1 param2` (as a *shell*) + +There can only be one CMD in a Dockerfile. If you list more than one CMD +then only the last CMD will take effect. + +**The main purpose of a CMD is to provide defaults for an executing +container.** These defaults can include an executable, or they can omit +the executable, in which case you must specify an ENTRYPOINT as well. + +When used in the shell or exec formats, the `CMD` +instruction sets the command to be executed when running the image. + +If you use the *shell* form of the CMD, then the `` +will execute in `/bin/sh -c`: + + FROM ubuntu + CMD echo "This is a test." | wc - + +If you want to **run your** `` **without a +shell** then you must express the command as a JSON array and give the +full path to the executable. **This array form is the preferred format +of CMD.** Any additional parameters must be individually expressed as +strings in the array: + + FROM ubuntu + CMD ["/usr/bin/wc","--help"] + +If you would like your container to run the same executable every time, +then you should consider using `ENTRYPOINT` in +combination with `CMD`. See +[*ENTRYPOINT*](#dockerfile-entrypoint). + +If the user specifies arguments to `docker run` then +they will override the default specified in CMD. + +Note + +Don’t confuse `RUN` with `CMD`. +`RUN` actually runs a command and commits the +result; `CMD` does not execute anything at build +time, but specifies the intended command for the image. + +## `EXPOSE` + +> `EXPOSE [...]` + +The `EXPOSE` instructions informs Docker that the +container will listen on the specified network ports at runtime. Docker +uses this information to interconnect containers using links (see +[*links*](../../use/working_with_links_names/#working-with-links-names)), +and to setup port redirection on the host system (see [*Redirect +Ports*](../../use/port_redirection/#port-redirection)). + +## `ENV` + +> `ENV ` + +The `ENV` instruction sets the environment variable +`` to the value ``. +This value will be passed to all future `RUN` +instructions. This is functionally equivalent to prefixing the command +with `=` + +The environment variables set using `ENV` will +persist when a container is run from the resulting image. You can view +the values using `docker inspect`, and change them +using `docker run --env =`. + +Note + +One example where this can cause unexpected consequenses, is setting +`ENV DEBIAN_FRONTEND noninteractive`. Which will +persist when the container is run interactively; for example: +`docker run -t -i image bash` + +## `ADD` + +> `ADD ` + +The `ADD` instruction will copy new files from +\ and add them to the container’s filesystem at path +``. + +`` must be the path to a file or directory +relative to the source directory being built (also called the *context* +of the build) or a remote file URL. + +`` is the absolute path to which the source +will be copied inside the destination container. + +All new files and directories are created with mode 0755, uid and gid 0. + +Note + +if you build using STDIN (`docker build - < somefile` +.literal}), there is no build context, so the Dockerfile can only +contain an URL based ADD statement. + +Note + +if your URL files are protected using authentication, you will need to +use an `RUN wget` , `RUN curl` +or other tool from within the container as ADD does not support +authentication. + +The copy obeys the following rules: + +- The `` path must be inside the *context* of + the build; you cannot `ADD ../something /something` +, because the first step of a `docker build` + is to send the context directory (and subdirectories) to + the docker daemon. + +- If `` is a URL and `` + does not end with a trailing slash, then a file is + downloaded from the URL and copied to ``. + +- If `` is a URL and `` + does end with a trailing slash, then the filename is + inferred from the URL and the file is downloaded to + `/`. For instance, + `ADD http://example.com/foobar /` would create + the file `/foobar`. The URL must have a + nontrivial path so that an appropriate filename can be discovered in + this case (`http://example.com` will not work). + +- If `` is a directory, the entire directory + is copied, including filesystem metadata. + +- If `` is a *local* tar archive in a + recognized compression format (identity, gzip, bzip2 or xz) then it + is unpacked as a directory. Resources from *remote* URLs are **not** + decompressed. + + When a directory is copied or unpacked, it has the same behavior as + `tar -x`: the result is the union of + + 1. whatever existed at the destination path and + 2. the contents of the source tree, + + with conflicts resolved in favor of "2." on a file-by-file basis. + +- If `` is any other kind of file, it is + copied individually along with its metadata. In this case, if + `` ends with a trailing slash + `/`, it will be considered a directory and the + contents of `` will be written at + `/base()`. + +- If `` does not end with a trailing slash, + it will be considered a regular file and the contents of + `` will be written at `` +. + +- If `` doesn’t exist, it is created along + with all missing directories in its path. + +## `ENTRYPOINT` + +ENTRYPOINT has two forms: + +- `ENTRYPOINT ["executable", "param1", "param2"]` + (like an *exec*, preferred form) +- `ENTRYPOINT command param1 param2` (as a + *shell*) + +There can only be one `ENTRYPOINT` in a Dockerfile. +If you have more than one `ENTRYPOINT`, then only +the last one in the Dockerfile will have an effect. + +An `ENTRYPOINT` helps you to configure a container +that you can run as an executable. That is, when you specify an +`ENTRYPOINT`, then the whole container runs as if it +was just that executable. + +The `ENTRYPOINT` instruction adds an entry command +that will **not** be overwritten when arguments are passed to +`docker run`, unlike the behavior of `CMD` +.literal}. This allows arguments to be passed to the entrypoint. i.e. +`docker run -d` will pass the "-d" argument +to the ENTRYPOINT. + +You can specify parameters either in the ENTRYPOINT JSON array (as in +"like an exec" above), or by using a CMD statement. Parameters in the +ENTRYPOINT will not be overridden by the `docker run` +arguments, but parameters specified via CMD will be overridden +by `docker run` arguments. + +Like a `CMD`, you can specify a plain string for the +ENTRYPOINT and it will execute in `/bin/sh -c`: + + FROM ubuntu + ENTRYPOINT wc -l - + +For example, that Dockerfile’s image will *always* take stdin as input +("-") and print the number of lines ("-l"). If you wanted to make this +optional but default, you could use a CMD: + + FROM ubuntu + CMD ["-l", "-"] + ENTRYPOINT ["/usr/bin/wc"] + +## `VOLUME` + +> `VOLUME ["/data"]` + +The `VOLUME` instruction will create a mount point +with the specified name and mark it as holding externally mounted +volumes from native host or other containers. For more +information/examples and mounting instructions via docker client, refer +to [*Share Directories via +Volumes*](../../use/working_with_volumes/#volume-def) documentation. + +## `USER` + +> `USER daemon` + +The `USER` instruction sets the username or UID to +use when running the image. + +## `WORKDIR` + +> `WORKDIR /path/to/workdir` + +The `WORKDIR` instruction sets the working directory +for the `RUN`, `CMD` and +`ENTRYPOINT` Dockerfile commands that follow it. + +It can be used multiple times in the one Dockerfile. If a relative path +is provided, it will be relative to the path of the previous +`WORKDIR` instruction. For example: + +> WORKDIR /a WORKDIR b WORKDIR c RUN pwd + +The output of the final `pwd` command in this +Dockerfile would be `/a/b/c`. + +## `ONBUILD` + +> `ONBUILD [INSTRUCTION]` + +The `ONBUILD` instruction adds to the image a +"trigger" instruction to be executed at a later time, when the image is +used as the base for another build. The trigger will be executed in the +context of the downstream build, as if it had been inserted immediately +after the *FROM* instruction in the downstream Dockerfile. + +Any build instruction can be registered as a trigger. + +This is useful if you are building an image which will be used as a base +to build other images, for example an application build environment or a +daemon which may be customized with user-specific configuration. + +For example, if your image is a reusable python application builder, it +will require application source code to be added in a particular +directory, and it might require a build script to be called *after* +that. You can’t just call *ADD* and *RUN* now, because you don’t yet +have access to the application source code, and it will be different for +each application build. You could simply provide application developers +with a boilerplate Dockerfile to copy-paste into their application, but +that is inefficient, error-prone and difficult to update because it +mixes with application-specific code. + +The solution is to use *ONBUILD* to register in advance instructions to +run later, during the next build stage. + +Here’s how it works: + +1. When it encounters an *ONBUILD* instruction, the builder adds a + trigger to the metadata of the image being built. The instruction + does not otherwise affect the current build. +2. At the end of the build, a list of all triggers is stored in the + image manifest, under the key *OnBuild*. They can be inspected with + *docker inspect*. +3. Later the image may be used as a base for a new build, using the + *FROM* instruction. As part of processing the *FROM* instruction, + the downstream builder looks for *ONBUILD* triggers, and executes + them in the same order they were registered. If any of the triggers + fail, the *FROM* instruction is aborted which in turn causes the + build to fail. If all triggers succeed, the FROM instruction + completes and the build continues as usual. +4. Triggers are cleared from the final image after being executed. In + other words they are not inherited by "grand-children" builds. + +For example you might add something like this: + + [...] + ONBUILD ADD . /app/src + ONBUILD RUN /usr/local/bin/python-build --dir /app/src + [...] + +Warning + +Chaining ONBUILD instructions using ONBUILD ONBUILD isn’t allowed. + +Warning + +ONBUILD may not trigger FROM or MAINTAINER instructions. + +## Dockerfile Examples + + # Nginx + # + # VERSION 0.0.1 + + FROM ubuntu + MAINTAINER Guillaume J.

Start the `webserver`, mapping port + `443` in the container to port `1443` + on the Docker server, setting the DNS server to + `dns.dev.org` and DNS search domain to + `dev.org`, creating a volume to put the log + files into (so we can access it from another container), then + importing the files from the volume exposed by the + `static` container, and linking to all exposed + ports from `riak` and `app`. + Lastly, we set the hostname to `web.sven.dev.org` + so its consistent with the pre-generated SSL certificate; +5.

Setting shared between operators and developers, where operators can + override defaults developers set in images at build time. + +Together, the `docker run [OPTIONS]` give complete +control over runtime behavior to the operator, allowing them to override +all defaults set by the developer during `docker build` +and nearly all the defaults set by the Docker runtime itself. + +## [Operator Exclusive Options](#id4) + +Only the operator (the person executing `docker run` +.literal}) can set the following options. + +- [Detached vs Foreground](#detached-vs-foreground) + - [Detached (-d)](#detached-d) + - [Foreground](#foreground) +- [Container Identification](#container-identification) + - [Name (–name)](#name-name) + - [PID Equivalent](#pid-equivalent) +- [Network Settings](#network-settings) +- [Clean Up (–rm)](#clean-up-rm) +- [Runtime Constraints on CPU and + Memory](#runtime-constraints-on-cpu-and-memory) +- [Runtime Privilege and LXC + Configuration](#runtime-privilege-and-lxc-configuration) + +### [Detached vs Foreground](#id2) + +When starting a Docker container, you must first decide if you want to +run the container in the background in a "detached" mode or in the +default foreground mode: + + -d=false: Detached mode: Run container in the background, print new container id + +#### [Detached (-d)](#id3) + +In detached mode (`-d=true` or just `-d` +.literal}), all I/O should be done through network connections or shared +volumes because the container is no longer listening to the commandline +where you executed `docker run`. You can reattach to +a detached container with `docker` +[*attach*](../commandline/cli/#cli-attach). If you choose to run a +container in the detached mode, then you cannot use the `--rm` +option. + +#### [Foreground](#id4) + +In foreground mode (the default when `-d` is not +specified), `docker run` can start the process in +the container and attach the console to the process’s standard input, +output, and standard error. It can even pretend to be a TTY (this is +what most commandline executables expect) and pass along signals. All of +that is configurable: + + -a=[] : Attach to ``stdin``, ``stdout`` and/or ``stderr`` + -t=false : Allocate a pseudo-tty + --sig-proxy=true: Proxify all received signal to the process (even in non-tty mode) + -i=false : Keep STDIN open even if not attached + +If you do not specify `-a` then Docker will [attach +everything +(stdin,stdout,stderr)](https://github.com/dotcloud/docker/blob/75a7f4d90cde0295bcfb7213004abce8d4779b75/commands.go#L1797). +You can specify to which of the three standard streams +(`stdin`, `stdout`, +`stderr`) you’d like to connect instead, as in: + + docker run -a stdin -a stdout -i -t ubuntu /bin/bash + +For interactive processes (like a shell) you will typically want a tty +as well as persistent standard input (`stdin`), so +you’ll use `-i -t` together in most interactive +cases. + +### [Container Identification](#id5) + +#### [Name (–name)](#id6) + +The operator can identify a container in three ways: + +- UUID long identifier + ("f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778") +- UUID short identifier ("f78375b1c487") +- Name ("evil\_ptolemy") + +The UUID identifiers come from the Docker daemon, and if you do not +assign a name to the container with `--name` then +the daemon will also generate a random string name too. The name can +become a handy way to add meaning to a container since you can use this +name when defining +[*links*](../../use/working_with_links_names/#working-with-links-names) +(or any other place you need to identify a container). This works for +both background and foreground Docker containers. + +#### [PID Equivalent](#id7) + +And finally, to help with automation, you can have Docker write the +container ID out to a file of your choosing. This is similar to how some +programs might write out their process ID to a file (you’ve seen them as +PID files): + + --cidfile="": Write the container ID to the file + +### [Network Settings](#id8) + + -n=true : Enable networking for this container + --dns=[] : Set custom dns servers for the container + +By default, all containers have networking enabled and they can make any +outgoing connections. The operator can completely disable networking +with `docker run -n` which disables all incoming and +outgoing networking. In cases like this, you would perform I/O through +files or STDIN/STDOUT only. + +Your container will use the same DNS servers as the host by default, but +you can override this with `--dns`. + +### [Clean Up (–rm)](#id9) + +By default a container’s file system persists even after the container +exits. This makes debugging a lot easier (since you can inspect the +final state) and you retain all your data by default. But if you are +running short-term **foreground** processes, these container file +systems can really pile up. If instead you’d like Docker to +**automatically clean up the container and remove the file system when +the container exits**, you can add the `--rm` flag: + + --rm=false: Automatically remove the container when it exits (incompatible with -d) + +### [Runtime Constraints on CPU and Memory](#id10) + +The operator can also adjust the performance parameters of the +container: + + -m="": Memory limit (format: , where unit = b, k, m or g) + -c=0 : CPU shares (relative weight) + +The operator can constrain the memory available to a container easily +with `docker run -m`. If the host supports swap +memory, then the `-m` memory setting can be larger +than physical RAM. + +Similarly the operator can increase the priority of this container with +the `-c` option. By default, all containers run at +the same priority and get the same proportion of CPU cycles, but you can +tell the kernel to give more shares of CPU time to one or more +containers when you start them via Docker. + +### [Runtime Privilege and LXC Configuration](#id11) + + --privileged=false: Give extended privileges to this container + --lxc-conf=[]: (lxc exec-driver only) Add custom lxc options --lxc-conf="lxc.cgroup.cpuset.cpus = 0,1" + +By default, Docker containers are "unprivileged" and cannot, for +example, run a Docker daemon inside a Docker container. This is because +by default a container is not allowed to access any devices, but a +"privileged" container is given access to all devices (see +[lxc-template.go](https://github.com/dotcloud/docker/blob/master/execdriver/lxc/lxc_template.go) +and documentation on [cgroups +devices](https://www.kernel.org/doc/Documentation/cgroups/devices.txt)). + +When the operator executes `docker run --privileged` +.literal}, Docker will enable to access to all devices on the host as +well as set some configuration in AppArmor to allow the container nearly +all the same access to the host as processes running outside containers +on the host. Additional information about running with +`--privileged` is available on the [Docker +Blog](http://blog.docker.io/2013/09/docker-can-now-run-within-docker/). + +If the Docker daemon was started using the `lxc` +exec-driver (`docker -d --exec-driver=lxc`) then the +operator can also specify LXC options using one or more +`--lxc-conf` parameters. These can be new parameters +or override existing parameters from the +[lxc-template.go](https://github.com/dotcloud/docker/blob/master/execdriver/lxc/lxc_template.go). +Note that in the future, a given host’s Docker daemon may not use LXC, +so this is an implementation-specific configuration meant for operators +already familiar with using LXC directly. + +## Overriding `Dockerfile` Image Defaults + +When a developer builds an image from a +[*Dockerfile*](../builder/#dockerbuilder) or when she commits it, the +developer can set a number of default parameters that take effect when +the image starts up as a container. + +Four of the `Dockerfile` commands cannot be +overridden at runtime: `FROM, MAINTAINER, RUN`, and +`ADD`. Everything else has a corresponding override +in `docker run`. We’ll go through what the developer +might have set in each `Dockerfile` instruction and +how the operator can override that setting. + +- [CMD (Default Command or Options)](#cmd-default-command-or-options) +- [ENTRYPOINT (Default Command to Execute at + Runtime](#entrypoint-default-command-to-execute-at-runtime) +- [EXPOSE (Incoming Ports)](#expose-incoming-ports) +- [ENV (Environment Variables)](#env-environment-variables) +- [VOLUME (Shared Filesystems)](#volume-shared-filesystems) +- [USER](#user) +- [WORKDIR](#workdir) + +### [CMD (Default Command or Options)](#id12) + +Recall the optional `COMMAND` in the Docker +commandline: + + docker run [OPTIONS] IMAGE[:TAG] [COMMAND] [ARG...] + +This command is optional because the person who created the +`IMAGE` may have already provided a default +`COMMAND` using the `Dockerfile` +`CMD`. As the operator (the person running a +container from the image), you can override that `CMD` +just by specifying a new `COMMAND`. + +If the image also specifies an `ENTRYPOINT` then the +`CMD` or `COMMAND` get appended +as arguments to the `ENTRYPOINT`. + +### [ENTRYPOINT (Default Command to Execute at Runtime](#id13) + + --entrypoint="": Overwrite the default entrypoint set by the image + +The ENTRYPOINT of an image is similar to a `COMMAND` +because it specifies what executable to run when the container starts, +but it is (purposely) more difficult to override. The +`ENTRYPOINT` gives a container its default nature or +behavior, so that when you set an `ENTRYPOINT` you +can run the container *as if it were that binary*, complete with default +options, and you can pass in more options via the `COMMAND` +.literal}. But, sometimes an operator may want to run something else +inside the container, so you can override the default +`ENTRYPOINT` at runtime by using a string to specify +the new `ENTRYPOINT`. Here is an example of how to +run a shell in a container that has been set up to automatically run +something else (like `/usr/bin/redis-server`): + + docker run -i -t --entrypoint /bin/bash example/redis + +or two examples of how to pass more parameters to that ENTRYPOINT: + + docker run -i -t --entrypoint /bin/bash example/redis -c ls -l + docker run -i -t --entrypoint /usr/bin/redis-cli example/redis --help + +### [EXPOSE (Incoming Ports)](#id14) + +The `Dockerfile` doesn’t give much control over +networking, only providing the `EXPOSE` instruction +to give a hint to the operator about what incoming ports might provide +services. The following options work with or override the +`Dockerfile`‘s exposed defaults: + + --expose=[]: Expose a port from the container + without publishing it to your host + -P=false : Publish all exposed ports to the host interfaces + -p=[] : Publish a container's port to the host (format: + ip:hostPort:containerPort | ip::containerPort | + hostPort:containerPort) + (use 'docker port' to see the actual mapping) + --link="" : Add link to another container (name:alias) + +As mentioned previously, `EXPOSE` (and +`--expose`) make a port available **in** a container +for incoming connections. The port number on the inside of the container +(where the service listens) does not need to be the same number as the +port exposed on the outside of the container (where clients connect), so +inside the container you might have an HTTP service listening on port 80 +(and so you `EXPOSE 80` in the +`Dockerfile`), but outside the container the port +might be 42800. + +To help a new client container reach the server container’s internal +port operator `--expose`‘d by the operator or +`EXPOSE`‘d by the developer, the operator has three +choices: start the server container with `-P` or +`-p,` or start the client container with +`--link`. + +If the operator uses `-P` or `-p` +then Docker will make the exposed port accessible on the host +and the ports will be available to any client that can reach the host. +To find the map between the host ports and the exposed ports, use +`docker port`) + +If the operator uses `--link` when starting the new +client container, then the client container can access the exposed port +via a private networking interface. Docker will set some environment +variables in the client container to help indicate which interface and +port to use. + +### [ENV (Environment Variables)](#id15) + +The operator can **set any environment variable** in the container by +using one or more `-e` flags, even overriding those +already defined by the developer with a Dockefile `ENV` +.literal}: + + $ docker run -e "deep=purple" --rm ubuntu /bin/bash -c export + declare -x HOME="/" + declare -x HOSTNAME="85bc26a0e200" + declare -x OLDPWD + declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" + declare -x PWD="/" + declare -x SHLVL="1" + declare -x container="lxc" + declare -x deep="purple" + +Similarly the operator can set the **hostname** with `-h` +.literal}. + +`--link name:alias` also sets environment variables, +using the *alias* string to define environment variables within the +container that give the IP and PORT information for connecting to the +service container. Let’s imagine we have a container running Redis: + + # Start the service container, named redis-name + $ docker run -d --name redis-name dockerfiles/redis + 4241164edf6f5aca5b0e9e4c9eccd899b0b8080c64c0cd26efe02166c73208f3 + + # The redis-name container exposed port 6379 + $ docker ps + CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES + 4241164edf6f dockerfiles/redis:latest /redis-stable/src/re 5 seconds ago Up 4 seconds 6379/tcp redis-name + + # Note that there are no public ports exposed since we didn't use -p or -P + $ docker port 4241164edf6f 6379 + 2014/01/25 00:55:38 Error: No public port '6379' published for 4241164edf6f + +Yet we can get information about the Redis container’s exposed ports +with `--link`.

This adds back in the references to private repositories and provides some refactoring to the Working with repositories documentation including updating references to the "Central" registry to Docker.io. It also: * Fixes some links and references to Central Index * Fixes anchors in other files to updated titles in Working with Repositories. * Renamed Central Index in the remaining places. * Updated terms documentation to reflect Docker.io * Updated some Docker Index naming to be consistent. * Updates menu labels and hyperlinks.

For instance, ``ADD http://example.com/foobar /`` - would create the file ``/foobar``. The URL must have a nontrivial path - so that an appropriate filename can be discovered in this case - (``http://example.com`` will not work). -* If ```` is a directory, the entire directory is copied, - including filesystem metadata. -* If ```` is a *local* tar archive in a recognized compression - format (identity, gzip, bzip2 or xz) then it is unpacked as a - directory. Resources from *remote* URLs are **not** decompressed. - - When a directory is copied or unpacked, it has the same behavior as - ``tar -x``: the result is the union of - - 1. whatever existed at the destination path and - 2. the contents of the source tree, - - with conflicts resolved in favor of "2." on a file-by-file basis. - -* If ```` is any other kind of file, it is copied individually - along with its metadata. In this case, if ```` ends with a - trailing slash ``/``, it will be considered a directory and the - contents of ```` will be written at ``/base()``. -* If ```` does not end with a trailing slash, it will be - considered a regular file and the contents of ```` will be - written at ````. -* If ```` doesn't exist, it is created along with all missing - directories in its path. - -.. _dockerfile_entrypoint: - -``ENTRYPOINT`` -============== - -ENTRYPOINT has two forms: - -* ``ENTRYPOINT ["executable", "param1", "param2"]`` (like an *exec*, - preferred form) -* ``ENTRYPOINT command param1 param2`` (as a *shell*) - -There can only be one ``ENTRYPOINT`` in a Dockerfile. If you have more -than one ``ENTRYPOINT``, then only the last one in the Dockerfile will -have an effect. - -An ``ENTRYPOINT`` helps you to configure a container that you can run -as an executable. That is, when you specify an ``ENTRYPOINT``, then -the whole container runs as if it was just that executable. - -The ``ENTRYPOINT`` instruction adds an entry command that will **not** -be overwritten when arguments are passed to ``docker run``, unlike the -behavior of ``CMD``. This allows arguments to be passed to the -entrypoint. i.e. ``docker run -d`` will pass the "-d" -argument to the ENTRYPOINT. - -You can specify parameters either in the ENTRYPOINT JSON array (as in -"like an exec" above), or by using a CMD statement. Parameters in the -ENTRYPOINT will not be overridden by the ``docker run`` arguments, but -parameters specified via CMD will be overridden by ``docker run`` -arguments. - -Like a ``CMD``, you can specify a plain string for the ENTRYPOINT and -it will execute in ``/bin/sh -c``: - -.. code-block:: bash - - FROM ubuntu - ENTRYPOINT wc -l - - -For example, that Dockerfile's image will *always* take stdin as input -("-") and print the number of lines ("-l"). If you wanted to make -this optional but default, you could use a CMD: - -.. code-block:: bash - - FROM ubuntu - CMD ["-l", "-"] - ENTRYPOINT ["/usr/bin/wc"] - -.. _dockerfile_volume: - -``VOLUME`` -========== - - ``VOLUME ["/data"]`` - -The ``VOLUME`` instruction will create a mount point with the specified name and mark it -as holding externally mounted volumes from native host or other containers. For more information/examples -and mounting instructions via docker client, refer to :ref:`volume_def` documentation. - -.. _dockerfile_user: - -``USER`` -======== - - ``USER daemon`` - -The ``USER`` instruction sets the username or UID to use when running -the image. - -.. _dockerfile_workdir: - -``WORKDIR`` -=========== - - ``WORKDIR /path/to/workdir`` - -The ``WORKDIR`` instruction sets the working directory for the ``RUN``, ``CMD`` and -``ENTRYPOINT`` Dockerfile commands that follow it. - -It can be used multiple times in the one Dockerfile. If a relative path is -provided, it will be relative to the path of the previous ``WORKDIR`` -instruction. For example: - - WORKDIR /a - WORKDIR b - WORKDIR c - RUN pwd - -The output of the final ``pwd`` command in this Dockerfile would be ``/a/b/c``. - -``ONBUILD`` -=========== - - ``ONBUILD [INSTRUCTION]`` - -The ``ONBUILD`` instruction adds to the image a "trigger" instruction to be -executed at a later time, when the image is used as the base for another build. -The trigger will be executed in the context of the downstream build, as if it -had been inserted immediately after the *FROM* instruction in the downstream -Dockerfile. - -Any build instruction can be registered as a trigger. - -This is useful if you are building an image which will be used as a base to build -other images, for example an application build environment or a daemon which may be -customized with user-specific configuration. - -For example, if your image is a reusable python application builder, it will require -application source code to be added in a particular directory, and it might require -a build script to be called *after* that. You can't just call *ADD* and *RUN* now, -because you don't yet have access to the application source code, and it will be -different for each application build. You could simply provide application developers -with a boilerplate Dockerfile to copy-paste into their application, but that is -inefficient, error-prone and difficult to update because it mixes with -application-specific code. - -The solution is to use *ONBUILD* to register in advance instructions to run later, -during the next build stage. - -Here's how it works: - -1. When it encounters an *ONBUILD* instruction, the builder adds a trigger to - the metadata of the image being built. - The instruction does not otherwise affect the current build. - -2. At the end of the build, a list of all triggers is stored in the image manifest, - under the key *OnBuild*. They can be inspected with *docker inspect*. - -3. Later the image may be used as a base for a new build, using the *FROM* instruction. - As part of processing the *FROM* instruction, the downstream builder looks for *ONBUILD* - triggers, and executes them in the same order they were registered. If any of the - triggers fail, the *FROM* instruction is aborted which in turn causes the build - to fail. If all triggers succeed, the FROM instruction completes and the build - continues as usual. - -4. Triggers are cleared from the final image after being executed. In other words - they are not inherited by "grand-children" builds. - -For example you might add something like this: - -.. code-block:: bash - - [...] - ONBUILD ADD . /app/src - ONBUILD RUN /usr/local/bin/python-build --dir /app/src - [...] - -.. warning:: Chaining ONBUILD instructions using `ONBUILD ONBUILD` isn't allowed. -.. warning:: ONBUILD may not trigger FROM or MAINTAINER instructions. - -.. _dockerfile_examples: - -Dockerfile Examples -====================== - -.. code-block:: bash - - # Nginx - # - # VERSION 0.0.1 - - FROM ubuntu - MAINTAINER Guillaume J.

You can -attach to the same container at the same time - screen sharing style, -or quickly view the progress of your daemonized process. - -You can detach from the container again (and leave it running) with -``CTRL-C`` (for a quiet exit) or ``CTRL-\`` to get a stacktrace of -the Docker client when it quits. When you detach from the container's -process the exit code will be returned to the client. - -To stop a container, use ``docker stop``. - -To kill the container, use ``docker kill``. - -.. _cli_attach_examples: - -Examples: -~~~~~~~~~ - -.. code-block:: bash - - $ ID=$(sudo docker run -d ubuntu /usr/bin/top -b) - $ sudo docker attach $ID - top - 02:05:52 up 3:05, 0 users, load average: 0.01, 0.02, 0.05 - Tasks: 1 total, 1 running, 0 sleeping, 0 stopped, 0 zombie - Cpu(s): 0.1%us, 0.2%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st - Mem: 373572k total, 355560k used, 18012k free, 27872k buffers - Swap: 786428k total, 0k used, 786428k free, 221740k cached - - PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND - 1 root 20 0 17200 1116 912 R 0 0.3 0:00.03 top - - top - 02:05:55 up 3:05, 0 users, load average: 0.01, 0.02, 0.05 - Tasks: 1 total, 1 running, 0 sleeping, 0 stopped, 0 zombie - Cpu(s): 0.0%us, 0.2%sy, 0.0%ni, 99.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st - Mem: 373572k total, 355244k used, 18328k free, 27872k buffers - Swap: 786428k total, 0k used, 786428k free, 221776k cached - - PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND - 1 root 20 0 17208 1144 932 R 0 0.3 0:00.03 top - - - top - 02:05:58 up 3:06, 0 users, load average: 0.01, 0.02, 0.05 - Tasks: 1 total, 1 running, 0 sleeping, 0 stopped, 0 zombie - Cpu(s): 0.2%us, 0.3%sy, 0.0%ni, 99.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st - Mem: 373572k total, 355780k used, 17792k free, 27880k buffers - Swap: 786428k total, 0k used, 786428k free, 221776k cached - - PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND - 1 root 20 0 17208 1144 932 R 0 0.3 0:00.03 top - ^C$ - $ sudo docker stop $ID - -.. _cli_build: - -``build`` ---------- - -:: - - Usage: docker build [OPTIONS] PATH | URL | - - Build a new container image from the source code at PATH - -t, --tag="": Repository name (and optionally a tag) to be applied - to the resulting image in case of success. - -q, --quiet=false: Suppress the verbose output generated by the containers. - --no-cache: Do not use the cache when building the image. - --rm=true: Remove intermediate containers after a successful build - -Use this command to build Docker images from a ``Dockerfile`` and a "context". - -The files at ``PATH`` or ``URL`` are called the "context" of the build. -The build process may refer to any of the files in the context, for example when -using an :ref:`ADD ` instruction. -When a single ``Dockerfile`` is given as ``URL``, then no context is set. - -When a Git repository is set as ``URL``, then the repository is used as the context. -The Git repository is cloned with its submodules (`git clone --recursive`). -A fresh git clone occurs in a temporary directory on your local host, and then this -is sent to the Docker daemon as the context. -This way, your local user credentials and vpn's etc can be used to access private repositories - -.. _cli_build_examples: - -.. seealso:: :ref:`dockerbuilder`. - -Examples: -~~~~~~~~~ - -.. code-block:: bash - - $ sudo docker build . - Uploading context 10240 bytes - Step 1 : FROM busybox - Pulling repository busybox - ---> e9aa60c60128MB/2.284 MB (100%) endpoint: https://cdn-registry-1.docker.io/v1/ - Step 2 : RUN ls -lh / - ---> Running in 9c9e81692ae9 - total 24 - drwxr-xr-x 2 root root 4.0K Mar 12 2013 bin - drwxr-xr-x 5 root root 4.0K Oct 19 00:19 dev - drwxr-xr-x 2 root root 4.0K Oct 19 00:19 etc - drwxr-xr-x 2 root root 4.0K Nov 15 23:34 lib - lrwxrwxrwx 1 root root 3 Mar 12 2013 lib64 -> lib - dr-xr-xr-x 116 root root 0 Nov 15 23:34 proc - lrwxrwxrwx 1 root root 3 Mar 12 2013 sbin -> bin - dr-xr-xr-x 13 root root 0 Nov 15 23:34 sys - drwxr-xr-x 2 root root 4.0K Mar 12 2013 tmp - drwxr-xr-x 2 root root 4.0K Nov 15 23:34 usr - ---> b35f4035db3f - Step 3 : CMD echo Hello World - ---> Running in 02071fceb21b - ---> f52f38b7823e - Successfully built f52f38b7823e - Removing intermediate container 9c9e81692ae9 - Removing intermediate container 02071fceb21b - - -This example specifies that the ``PATH`` is ``.``, and so all the files in -the local directory get tar'd and sent to the Docker daemon.

This is similar to how -some programs might write out their process ID to a file (you've seen -them as PID files):: - - --cidfile="": Write the container ID to the file - -Network Settings ----------------- - -:: - - -n=true : Enable networking for this container - --dns=[] : Set custom dns servers for the container - -By default, all containers have networking enabled and they can make -any outgoing connections. The operator can completely disable -networking with ``docker run -n`` which disables all incoming and outgoing -networking. In cases like this, you would perform I/O through files or -STDIN/STDOUT only. - -Your container will use the same DNS servers as the host by default, -but you can override this with ``--dns``. - -Clean Up (--rm) ---------------- - -By default a container's file system persists even after the container -exits. This makes debugging a lot easier (since you can inspect the -final state) and you retain all your data by default. But if you are -running short-term **foreground** processes, these container file -systems can really pile up. If instead you'd like Docker to -**automatically clean up the container and remove the file system when -the container exits**, you can add the ``--rm`` flag:: - - --rm=false: Automatically remove the container when it exits (incompatible with -d) - - -Runtime Constraints on CPU and Memory -------------------------------------- - -The operator can also adjust the performance parameters of the container:: - - -m="": Memory limit (format: , where unit = b, k, m or g) - -c=0 : CPU shares (relative weight) - -The operator can constrain the memory available to a container easily -with ``docker run -m``. If the host supports swap memory, then the -``-m`` memory setting can be larger than physical RAM. - -Similarly the operator can increase the priority of this container -with the ``-c`` option. By default, all containers run at the same -priority and get the same proportion of CPU cycles, but you can tell -the kernel to give more shares of CPU time to one or more containers -when you start them via Docker. - -Runtime Privilege and LXC Configuration ---------------------------------------- - -:: - - --privileged=false: Give extended privileges to this container - --lxc-conf=[]: (lxc exec-driver only) Add custom lxc options --lxc-conf="lxc.cgroup.cpuset.cpus = 0,1" - -By default, Docker containers are "unprivileged" and cannot, for -example, run a Docker daemon inside a Docker container. This is -because by default a container is not allowed to access any devices, -but a "privileged" container is given access to all devices (see -lxc-template.go_ and documentation on `cgroups devices -`_). - -When the operator executes ``docker run --privileged``, Docker will -enable to access to all devices on the host as well as set some -configuration in AppArmor to allow the container nearly all the same -access to the host as processes running outside containers on the -host. Additional information about running with ``--privileged`` is -available on the `Docker Blog -`_. - -If the Docker daemon was started using the ``lxc`` exec-driver -(``docker -d --exec-driver=lxc``) then the operator can also specify -LXC options using one or more ``--lxc-conf`` parameters. These can be -new parameters or override existing parameters from the lxc-template.go_. -Note that in the future, a given host's Docker daemon may not use LXC, -so this is an implementation-specific configuration meant for operators -already familiar with using LXC directly. - -.. _lxc-template.go: https://github.com/dotcloud/docker/blob/master/execdriver/lxc/lxc_template.go - - -Overriding ``Dockerfile`` Image Defaults -======================================== - -When a developer builds an image from a :ref:`Dockerfile -` or when she commits it, the developer can set a -number of default parameters that take effect when the image starts up -as a container. - -Four of the ``Dockerfile`` commands cannot be overridden at runtime: -``FROM, MAINTAINER, RUN``, and ``ADD``. Everything else has a -corresponding override in ``docker run``. We'll go through what the -developer might have set in each ``Dockerfile`` instruction and how the -operator can override that setting. - -.. contents:: - :local: - -CMD (Default Command or Options) --------------------------------- - -Recall the optional ``COMMAND`` in the Docker commandline:: - - docker run [OPTIONS] IMAGE[:TAG] [COMMAND] [ARG...] - -This command is optional because the person who created the ``IMAGE`` -may have already provided a default ``COMMAND`` using the ``Dockerfile`` -``CMD``. As the operator (the person running a container from the -image), you can override that ``CMD`` just by specifying a new -``COMMAND``. - -If the image also specifies an ``ENTRYPOINT`` then the ``CMD`` or -``COMMAND`` get appended as arguments to the ``ENTRYPOINT``. - - -ENTRYPOINT (Default Command to Execute at Runtime -------------------------------------------------- - -:: - - --entrypoint="": Overwrite the default entrypoint set by the image - -The ENTRYPOINT of an image is similar to a ``COMMAND`` because it -specifies what executable to run when the container starts, but it is -(purposely) more difficult to override. The ``ENTRYPOINT`` gives a -container its default nature or behavior, so that when you set an -``ENTRYPOINT`` you can run the container *as if it were that binary*, -complete with default options, and you can pass in more options via -the ``COMMAND``. But, sometimes an operator may want to run something else -inside the container, so you can override the default ``ENTRYPOINT`` at -runtime by using a string to specify the new ``ENTRYPOINT``. Here is an -example of how to run a shell in a container that has been set up to -automatically run something else (like ``/usr/bin/redis-server``):: - - docker run -i -t --entrypoint /bin/bash example/redis - -or two examples of how to pass more parameters to that ENTRYPOINT:: - - docker run -i -t --entrypoint /bin/bash example/redis -c ls -l - docker run -i -t --entrypoint /usr/bin/redis-cli example/redis --help - - -EXPOSE (Incoming Ports) ------------------------ - -The ``Dockerfile`` doesn't give much control over networking, only -providing the ``EXPOSE`` instruction to give a hint to the operator -about what incoming ports might provide services. The following -options work with or override the ``Dockerfile``'s exposed defaults:: - - --expose=[]: Expose a port from the container - without publishing it to your host - -P=false : Publish all exposed ports to the host interfaces - -p=[] : Publish a container's port to the host (format: - ip:hostPort:containerPort | ip::containerPort | - hostPort:containerPort) - (use 'docker port' to see the actual mapping) - --link="" : Add link to another container (name:alias) - -As mentioned previously, ``EXPOSE`` (and ``--expose``) make a port -available **in** a container for incoming connections. The port number -on the inside of the container (where the service listens) does not -need to be the same number as the port exposed on the outside of the -container (where clients connect), so inside the container you might -have an HTTP service listening on port 80 (and so you ``EXPOSE 80`` in -the ``Dockerfile``), but outside the container the port might be 42800. - -To help a new client container reach the server container's internal -port operator ``--expose``'d by the operator or ``EXPOSE``'d by the -developer, the operator has three choices: start the server container -with ``-P`` or ``-p,`` or start the client container with ``--link``. - -If the operator uses ``-P`` or ``-p`` then Docker will make the -exposed port accessible on the host and the ports will be available to -any client that can reach the host. To find the map between the host -ports and the exposed ports, use ``docker port``) - -If the operator uses ``--link`` when starting the new client container, -then the client container can access the exposed port via a private -networking interface. Docker will set some environment variables in -the client container to help indicate which interface and port to use. - -ENV (Environment Variables) ---------------------------- - -The operator can **set any environment variable** in the container by -using one or more ``-e`` flags, even overriding those already defined by the -developer with a Dockefile ``ENV``:: - - $ docker run -e "deep=purple" --rm ubuntu /bin/bash -c export - declare -x HOME="/" - declare -x HOSTNAME="85bc26a0e200" - declare -x OLDPWD - declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" - declare -x PWD="/" - declare -x SHLVL="1" - declare -x container="lxc" - declare -x deep="purple" - -Similarly the operator can set the **hostname** with ``-h``. - -``--link name:alias`` also sets environment variables, using the -*alias* string to define environment variables within the container -that give the IP and PORT information for connecting to the service -container.

Start a pre-prepared ``riakserver`` image, give the container name ``riak`` and expose port ``8098`` to any containers that link to it; +3. Start the ``appserver`` image, restricting its memory usage to 100MB, setting two environment variables ``DEVELOPMENT`` and ``BRANCH`` and bind-mounting the current directory (``$(pwd)``) in the container in read-only mode as ``/app/bin``; +4. Start the ``webserver``, mapping port ``443`` in the container to port ``1443`` on the Docker server, setting the DNS server to ``dns.dev.org`` and DNS search domain to ``dev.org``, creating a volume to put the log files into (so we can access it from another container), then importing the files from the volume exposed by the ``static`` container, and linking to all exposed ports from ``riak`` and ``app``. Lastly, we set the hostname to ``web.sven.dev.org`` so its consistent with the pre-generated SSL certificate; +5. Finally, we create a container that runs ``tail -f access.log`` using the logs volume from the ``web`` container, setting the workdir to ``/var/log/httpd``.

QE teams have requested this change, also users doing docker help | less or docker run --help | less would expect this to work. Usage statement should only be printed when the user asks for it. Errors should print error message and then suggest the docker COMMAND --help command to see usage information. The current behaviour causes the user to have to search for the error message and sometimes scrolls right off the screen. For example a error on a "docker run" command is very difficult to diagnose. Finally erros should always exit with a non 0 exit code, if the user makes a CLI error.

QE teams have requested this change, also users doing docker help | less or docker run --help | less would expect this to work. Usage statement should only be printed when the user asks for it. Errors should print error message and then suggest the docker COMMAND --help command to see usage information. The current behaviour causes the user to have to search for the error message and sometimes scrolls right off the screen. For example a error on a "docker run" command is very difficult to diagnose. Finally erros should always exit with a non 0 exit code, if the user makes a CLI error.

I don't see us needing to share PID namespaces between containers, since this is really what docker exec does.

For +example, `flocker` or `weave`. + +Plugins can run inside or outside containers. Currently running them outside +containers is recommended. + +## Plugin discovery + +Docker discovers plugins by looking for them in the plugin directory whenever a +user or container tries to use one by name. + +There are two types of files which can be put in the plugin directory. + +* `.sock` files are UNIX domain sockets. +* `.spec` files are text files containing a URL, such as `unix:///other.sock`. + +The name of the file (excluding the extension) determines the plugin name. + +For example, the `flocker` plugin might create a UNIX socket at +`/usr/share/docker/plugins/flocker.sock`. + +Plugins must be run locally on the same machine as the Docker daemon. UNIX +domain sockets are strongly encouraged for security reasons. + +## Plugin lifecycle + +Plugins should be started before Docker, and stopped after Docker. For +example, when packaging a plugin for a platform which supports `systemd`, you +might use [`systemd` dependencies]( +http://www.freedesktop.org/software/systemd/man/systemd.unit.html#Before=) to +manage startup and shutdown order. + +When upgrading a plugin, you should first stop the Docker daemon, upgrade the +plugin, then start Docker again. + +If a plugin is packaged as a container, this may cause issues. Plugins as +containers are currently considered experimental due to these shutdown/startup +ordering issues. These issues are mitigated by plugin retries (see below). + +## Plugin activation + +When a plugin is first referred to -- either by a user referring to it by name +(e.g. `docker run --volume-driver=foo`) or a container already configured to +use a plugin being started -- Docker looks for the named plugin in the plugin +directory and activates it with a handshake. See Handshake API below. + +Plugins are *not* activated automatically at Docker daemon startup. Rather, +they are activated only lazily, or on-demand, when they are needed. + +## API design + +The Plugin API is RPC-style JSON over HTTP, much like webhooks. + +Requests flow *from* the Docker daemon *to* the plugin. So the plugin needs to +implement an HTTP server and bind this to the UNIX socket mentioned in the +"plugin discovery" section. + +All requests are HTTP `POST` requests. + +The API is versioned via an Accept header, which currently is always set to +`application/vnd.docker.plugins.v1+json`. + +## Handshake API + +Plugins are activated via the following "handshake" API call. + +### /Plugin.Activate + +**Request:** empty body + +**Response:** +``` +{ + "Implements": ["VolumeDriver"] +} +``` + +Responds with a list of Docker subsystems which this plugin implements. +After activation, the plugin will then be sent events from this subsystem. + +## Volume API + +If a plugin registers itself as a `VolumeDriver` (see above) then it is +expected to provide writeable paths on the host filesystem for the Docker +daemon to provide to containers to consume. + +The Docker daemon handles bind-mounting the provided paths into user +containers. + +### /VolumeDriver.Create + +**Request**: +``` +{ + "Name": "volume_name" +} +``` + +Instruct the plugin that the user wants to create a volume, given a user +specified volume name.

A trigger is useful if + you are defining an image to use as a base for building other images. For + example, if you are defining an application build environment or a daemon that + is customized with a user-specific configuration. + + Consider an image intended as a reusable python application builder.

The actual amount of CPU time used varies depending on + the number of containers running on the system. + + For example, consider three containers, one has a cpu-share of 1024 and + two others have a cpu-share setting of 512.

In order to +keep them, you must explicitly set `--rm=false`. + + docker build --rm=false . + +A good practice is to make a sub-directory with a related name and create +the Dockerfile in that directory. For example, a directory called mongo may +contain a Dockerfile to create a Docker MongoDB image.

There are +no hard rules here but it is best to give the names consideration. + +The **-t**/**--tag** flag is used to rename an image. Here are some examples: + +Though it is not a good practice, image names can be arbitrary: + + docker build -t myimage . + +A better approach is to provide a fully qualified and meaningful repository, +name, and tag (where the tag in this context means the qualifier after +the ":"). In this example we build a JBoss image for the Fedora repository +and give it the version 1.0: + + docker build -t fedora/jboss:1.0 + +The next example is for the "whenry" user repository and uses Fedora and +JBoss and gives it the version 2.1 : + + docker build -t whenry/fedora-jboss:V2.1 + +If you do not provide a version tag then Docker will assign `latest`: + + docker build -t whenry/fedora-jboss + +When you list the images, the image above will have the tag `latest`. + +So renaming an image is arbitrary but consideration should be given to +a useful convention that makes sense for consumers and should also take +into account Docker community conventions. + + +## Building an image using a URL + +This will clone the specified Github repository from the URL and use it +as context.

The IMAGE +which starts the process may define defaults related to the process that will be +run in the container, the networking to expose, and more, but **docker run** +gives final control to the operator or administrator who starts the container +from the image. For that reason **docker run** has more options than any other +Docker command. + +If the IMAGE is not already loaded then **docker run** will pull the IMAGE, and +all image dependencies, from the repository in the same way running **docker +pull** IMAGE, before it starts the container from that image. + +# OPTIONS +**-a**, **--attach**=[] + Attach to STDIN, STDOUT or STDERR. + + In foreground mode (the default when **-d** +is not specified), **docker run** can start the process in the container +and attach the console to the process’s standard input, output, and standard +error. It can even pretend to be a TTY (this is what most commandline +executables expect) and pass along signals. The **-a** option can be set for +each of stdin, stdout, and stderr. + +**--add-host**=[] + Add a custom host-to-IP mapping (host:ip) + + Add a line to /etc/hosts. The format is hostname:ip. The **--add-host** +option can be set multiple times. + +**--blkio-weight**=0 + Block IO weight (relative weight) accepts a weight value between 10 and 1000. + +**-c**, **--cpu-shares**=0 + CPU shares (relative weight) + + By default, all containers get the same proportion of CPU cycles. This proportion +can be modified by changing the container's CPU share weighting relative +to the weighting of all other running containers. + +To modify the proportion from the default of 1024, use the **-c** or **--cpu-shares** +flag to set the weighting to 2 or higher. + +The proportion will only apply when CPU-intensive processes are running. +When tasks in one container are idle, other containers can use the +left-over CPU time. The actual amount of CPU time will vary depending on +the number of containers running on the system. + +For example, consider three containers, one has a cpu-share of 1024 and +two others have a cpu-share setting of 512. When processes in all three +containers attempt to use 100% of CPU, the first container would receive +50% of the total CPU time. If you add a fourth container with a cpu-share +of 1024, the first container only gets 33% of the CPU. The remaining containers +receive 16.5%, 16.5% and 33% of the CPU. + +On a multi-core system, the shares of CPU time are distributed over all CPU +cores. Even if a container is limited to less than 100% of CPU time, it can +use 100% of each individual CPU core. + +For example, consider a system with more than three cores. If you start one +container **{C0}** with **-c=512** running one process, and another container +**{C1}** with **-c=1024** running two processes, this can result in the following +division of CPU shares: + + PID container CPU CPU share + 100 {C0} 0 100% of CPU0 + 101 {C1} 1 100% of CPU1 + 102 {C1} 2 100% of CPU2 + +**--cap-add**=[] + Add Linux capabilities + +**--cap-drop**=[] + Drop Linux capabilities + +**--cgroup-parent**="" + Path to cgroups under which the cgroup for the container will be created.

The default is *false*. + + By default, Docker containers are +“unprivileged” (=false) and cannot, for example, run a Docker daemon inside the +Docker container.

By default, the volumes are mounted +read-write. See examples. + +Labeling systems like SELinux require that proper labels are placed on volume +content mounted into a container. Without a label, the security system might +prevent the processes running inside the container from using the content. By +default, Docker does not change the labels set by the OS. + +To change a label in the container context, you can add either of two suffixes +`:z` or `:Z` to the volume mount. These suffixes tell Docker to relabel file +objects on the shared volumes. The `z` option tells Docker that two containers +share the volume content. As a result, Docker labels the content with a shared +content label. Shared volume labels allow all containers to read/write content. +The `Z` option tells Docker to label the content with a private unshared label. +Only the current container can use a private volume. + +Note: Multiple Volume options can be added separated by a "," + +**--volumes-from**=[] + Mount volumes from the specified container(s) + + Mounts already mounted volumes from a source container onto another + container. You must supply the source's container-id. To share + a volume, use the **--volumes-from** option when running + the target container. You can share volumes even if the source container + is not running. + + By default, Docker mounts the volumes in the same mode (read-write or + read-only) as it is mounted in the source container. Optionally, you + can change this by suffixing the container-id with either the `:ro` or + `:rw ` keyword. + + If the location of the volume from the source container overlaps with + data residing on a target container, then the volume hides + that data on the target. + +**-w**, **--workdir**="" + Working directory inside the container + + The default working directory for +running binaries within a container is the root directory (/).

For +example, a container whose Dockerfile has exposed port 80 can be run and named +as follows: + + # docker run --name=link-test -d -i -t fedora/httpd + +A second container, in this case called linker, can communicate with the httpd +container, named link-test, by running with the **--link=:** + + # docker run -t -i --link=link-test:lt --name=linker fedora /bin/bash + +Now the container linker is linked to container link-test with the alias lt. +Running the **env** command in the linker container shows environment variables + with the LT (alias) context (**LT_**) + + # env + HOSTNAME=668231cb0978 + TERM=xterm + LT_PORT_80_TCP=tcp://172.17.0.3:80 + LT_PORT_80_TCP_PORT=80 + LT_PORT_80_TCP_PROTO=tcp + LT_PORT=tcp://172.17.0.3:80 + PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin + PWD=/ + LT_NAME=/linker/lt + SHLVL=1 + HOME=/ + LT_PORT_80_TCP_ADDR=172.17.0.3 + _=/usr/bin/env + +When linking two containers Docker will use the exposed ports of the container +to create a secure tunnel for the parent to access. + + +## Mapping Ports for External Usage + +The exposed port of an application can be mapped to a host port using the **-p** +flag. For example, a httpd port 80 can be mapped to the host port 8080 using the +following: + + # docker run -p 8080:80 -d -i -t fedora/httpd + +## Creating and Mounting a Data Volume Container + +Many applications require the sharing of persistent data across several +containers. Docker allows you to create a Data Volume Container that other +containers can mount from. For example, create a named container that contains +directories /var/volume1 and /tmp/volume2. The image will need to contain these +directories so a couple of RUN mkdir instructions might be required for you +fedora-data image: + + # docker run --name=data -v /var/volume1 -v /tmp/volume2 -i -t fedora-data true + # docker run --volumes-from=data --name=fedora-container1 -i -t fedora bash + +Multiple --volumes-from parameters will bring together multiple data volumes from +multiple containers. And it's possible to mount the volumes that came from the +DATA container in yet another container via the fedora-container1 intermediary +container, allowing to abstract the actual data source from users of that data: + + # docker run --volumes-from=fedora-container1 --name=fedora-container2 -i -t fedora bash + +## Mounting External Volumes + +To mount a host directory as a container volume, specify the absolute path to +the directory and the absolute path for the container directory separated by a +colon: + + # docker run -v /var/db:/data1 -i -t fedora bash + +When using SELinux, be aware that the host has no knowledge of container SELinux +policy. Therefore, in the above example, if SELinux policy is enforced, the +`/var/db` directory is not writable to the container. A "Permission Denied" +message will occur and an avc: message in the host's syslog. + + +To work around this, at time of writing this man page, the following command +needs to be run in order for the proper SELinux policy type label to be attached +to the host directory: + + # chcon -Rt svirt_sandbox_file_t /var/db + + +Now, writing to the /data1 volume in the container will be allowed and the +changes will also be reflected on the host in /var/db. + +## Using alternative security labeling + +You can override the default labeling scheme for each container by specifying +the `--security-opt` flag. For example, you can specify the MCS/MLS level, a +requirement for MLS systems.

The +only backend which currently takes options is *devicemapper*. Therefore use these +flags with **-s=**devicemapper. + +Here is the list of *devicemapper* options: + +#### dm.basesize +Specifies the size to use when creating the base device, which limits the size +of images and containers. The default value is 10G. Note, thin devices are +inherently "sparse", so a 10G device which is mostly empty doesn't use 10 GB +of space on the pool. However, the filesystem will use more space for the empty +case the larger the device is. **Warning**: This value affects the system-wide +"base" empty filesystem that may already be initialized and inherited by pulled +images. + +#### dm.loopdatasize +Specifies the size to use when creating the loopback file for the "data" +device which is used for the thin pool. The default size is 100G. Note that the +file is sparse, so it will not initially take up this much space. + +#### dm.loopmetadatasize +Specifies the size to use when creating the loopback file for the "metadadata" +device which is used for the thin pool. The default size is 2G. Note that the +file is sparse, so it will not initially take up this much space. + +#### dm.fs +Specifies the filesystem type to use for the base device. The supported +options are "ext4" and "xfs". The default is "ext4" + +#### dm.mkfsarg +Specifies extra mkfs arguments to be used when creating the base device. + +#### dm.mountopt +Specifies extra mount options used when mounting the thin devices. + +#### dm.datadev +Specifies a custom blockdevice to use for data for the thin pool. + +If using a block device for device mapper storage, ideally both datadev and +metadatadev should be specified to completely avoid using the loopback device. + +#### dm.metadatadev +Specifies a custom blockdevice to use for metadata for the thin pool. + +For best performance the metadata should be on a different spindle than the +data, or even better on an SSD. + +If setting up a new metadata pool it is required to be valid. This can be +achieved by zeroing the first 4k to indicate empty metadata, like this: + + dd if=/dev/zero of=/dev/metadata_dev bs=4096 count=1 + +#### dm.blocksize +Specifies a custom blocksize to use for the thin pool. The default blocksize +is 64K. + +#### dm.blkdiscard +Enables or disables the use of blkdiscard when removing devicemapper devices. +This is enabled by default (only) if using loopback devices and is required to +resparsify the loopback file on image/container removal. + +Disabling this on loopback can lead to *much* faster container removal times, +but will prevent the space used in `/var/lib/docker` directory from being returned to +the system for other use when containers are removed. + +# EXAMPLES +Launching docker daemon with *devicemapper* backend with particular block devices +for data and metadata: + + docker -d -s=devicemapper \ + --storage-opt dm.datadev=/dev/vdb \ + --storage-opt dm.metadatadev=/dev/vdc \ + --storage-opt dm.basesize=20G + +# EXEC DRIVER OPTIONS + +Use the **--exec-opt** flags to specify options to the exec-driver. The only +driver that accepts this flag is the *native* (libcontainer) driver. As a +result, you must also specify **-s=**native for this option to have effect.

Fix the journald driver by adding a dummy validator. Teach the client and the daemon's "logs" logic that the server can also supply "logs" data via the "journald" driver. Update documentation and tests that depend on error messages. Add support for reading log data from the systemd journal to the journald log driver. The internal logic uses a goroutine to scan the journal for matching entries after any specified cutoff time, formats the messages from those entries as JSONLog messages, and stuffs the results down a pipe whose reading end we hand back to the caller. If we are missing any of the 'linux', 'cgo', or 'journald' build tags, however, we don't implement a reader, so the 'logs' endpoint will still return an error. Make the necessary changes to the build setup to ensure that support for reading container logs from the systemd journal is built. Rename the Jmap member of the journald logdriver's struct to "vars" to make it non-public, and to make it easier to tell that it's just there to hold additional variable values that we want journald to record along with log data that we're sending to it. In the client, don't assume that we know which logdrivers the server implements, and remove the check that looks at the server. It's redundant because the server already knows, and the check also makes using older clients with newer servers (which may have new logdrivers in them) unnecessarily hard. When we try to "logs" and have to report that the container's logdriver doesn't support reading, send the error message through the might-be-a-multiplexer so that clients which are expecting multiplexed data will be able to properly display the error, instead of tripping over the data and printing a less helpful "Unrecognized input header" error.

These variables are not persisted in environment of intermediate and final images when passed as context for RUN. The build environment is prepended to the intermediate continer's command string for aiding cache lookups. It also helps with build traceability. But this also makes the feature less secure from point of view of passing build time secrets. - The build-time variables also get used to expand the symbols used in certain Dockerfile primitves like ADD, COPY, USER etc, without an explicit prior definiton using a ENV primitive. These variables get persisted in the intermediate and final images whenever they are expanded. - The build-time variables are only expanded or passed to the RUN primtive if they are defined in Dockerfile using the ARG primitive or belong to list of built-in variables. HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy, FTP_PROXY and NO_PROXY are built-in variables that needn't be explicitly defined in Dockerfile to use this feature.

Many of these +backends use operating system level technologies and can be +configured. + +Specify options to the storage backend with **--storage-opt** flags. The only +backend that currently takes options is *devicemapper*. Therefore use these +flags with **-s=**devicemapper. + +Specifically for devicemapper, the default is a "loopback" model which +requires no pre-configuration, but is extremely inefficient. Do not +use it in production. + +To make the best use of Docker with the devicemapper backend, you must +have a recent version of LVM. Use `lvm` to create a thin pool; for +more information see `man lvmthin`. Then, use `--storage-opt +dm.thinpooldev` to tell the Docker engine to use that pool for +allocating images and container snapshots. + +Here is the list of *devicemapper* options: + +#### dm.thinpooldev + +Specifies a custom block storage device to use for the thin pool. + +If using a block device for device mapper storage, it is best to use +`lvm` to create and manage the thin-pool volume. This volume is then +handed to Docker to create snapshot volumes needed for images and +containers. + +Managing the thin-pool outside of Docker makes for the most feature-rich method +of having Docker utilize device mapper thin provisioning as the backing storage +for Docker's containers. The highlights of the LVM-based thin-pool management +feature include: automatic or interactive thin-pool resize support, dynamically +changing thin-pool features, automatic thinp metadata checking when lvm activates +the thin-pool, etc. + +Example use: `docker daemon --storage-opt dm.thinpooldev=/dev/mapper/thin-pool` + +#### dm.basesize + +Specifies the size to use when creating the base device, which limits +the size of images and containers. The default value is 100G. Note, +thin devices are inherently "sparse", so a 100G device which is mostly +empty doesn't use 100 GB of space on the pool. However, the filesystem +will use more space for base images the larger the device +is. + +This value affects the system-wide "base" empty filesystem that may already +be initialized and inherited by pulled images. Typically, a change to this +value requires additional steps to take effect: + + $ sudo service docker stop + $ sudo rm -rf /var/lib/docker + $ sudo service docker start + +Example use: `docker daemon --storage-opt dm.basesize=20G` + +#### dm.fs + +Specifies the filesystem type to use for the base device. The +supported options are `ext4` and `xfs`. The default is `ext4`. + +Example use: `docker daemon --storage-opt dm.fs=xfs` + +#### dm.mkfsarg + +Specifies extra mkfs arguments to be used when creating the base device. + +Example use: `docker daemon --storage-opt "dm.mkfsarg=-O ^has_journal"` + +#### dm.mountopt + +Specifies extra mount options used when mounting the thin devices. + +Example use: `docker daemon --storage-opt dm.mountopt=nodiscard` + +#### dm.use_deferred_removal + +Enables use of deferred device removal if `libdm` and the kernel driver +support the mechanism. + +Deferred device removal means that if device is busy when devices are +being removed/deactivated, then a deferred removal is scheduled on +device. And devices automatically go away when last user of the device +exits. + +For example, when a container exits, its associated thin device is removed. If +that device has leaked into some other mount namespace and can't be removed, +the container exit still succeeds and this option causes the system to schedule +the device for deferred removal. It does not wait in a loop trying to remove a busy +device. + +Example use: `docker daemon --storage-opt dm.use_deferred_removal=true` + +#### dm.loopdatasize + +**Note**: This option configures devicemapper loopback, which should not be used in production. + +Specifies the size to use when creating the loopback file for the +"data" device which is used for the thin pool. The default size is +100G. The file is sparse, so it will not initially take up +this much space. + +Example use: `docker daemon --storage-opt dm.loopdatasize=200G` + +#### dm.loopmetadatasize + +**Note**: This option configures devicemapper loopback, which should not be used in production. + +Specifies the size to use when creating the loopback file for the +"metadata" device which is used for the thin pool. The default size +is 2G. The file is sparse, so it will not initially take up +this much space. + +Example use: `docker daemon --storage-opt dm.loopmetadatasize=4G` + +#### dm.datadev + +(Deprecated, use `dm.thinpooldev`) + +Specifies a custom blockdevice to use for data for a +Docker-managed thin pool. It is better to use `dm.thinpooldev` - see +the documentation for it above for discussion of the advantages. + +#### dm.metadatadev + +(Deprecated, use `dm.thinpooldev`) + +Specifies a custom blockdevice to use for metadata for a +Docker-managed thin pool. See `dm.datadev` for why this is +deprecated. + +#### dm.blocksize + +Specifies a custom blocksize to use for the thin pool. The default +blocksize is 64K. + +Example use: `docker daemon --storage-opt dm.blocksize=512K` + +#### dm.blkdiscard + +Enables or disables the use of `blkdiscard` when removing devicemapper +devices. This is disabled by default due to the additional latency, +but as a special case with loopback devices it will be enabled, in +order to re-sparsify the loopback file on image/container removal. + +Disabling this on loopback can lead to *much* faster container removal +times, but it also prevents the space used in `/var/lib/docker` directory +from being returned to the system for other use when containers are +removed. + +Example use: `docker daemon --storage-opt dm.blkdiscard=false` + +#### dm.override_udev_sync_check + +By default, the devicemapper backend attempts to synchronize with the +`udev` device manager for the Linux kernel. This option allows +disabling that synchronization, to continue even though the +configuration may be buggy. + +To view the `udev` sync support of a Docker daemon that is using the +`devicemapper` driver, run: + + $ docker info + [...] + Udev Sync Supported: true + [...] + +When `udev` sync support is `true`, then `devicemapper` and `udev` can +coordinate the activation and deactivation of devices for containers. + +When `udev` sync support is `false`, a race condition occurs between +the `devicemapper` and `udev` during create and cleanup. The race +condition results in errors and failures. (For information on these +failures, see +[docker#4036](https://github.com/docker/docker/issues/4036)) + +To allow the `docker` daemon to start, regardless of whether `udev` sync is +`false`, set `dm.override_udev_sync_check` to true: + + $ docker daemon --storage-opt dm.override_udev_sync_check=true + +When this value is `true`, the driver continues and simply warns you +the errors are happening. + +**Note**: The ideal is to pursue a `docker` daemon and environment +that does support synchronizing with `udev`.

The functionality is driven by two different command-line flags: the experimental `--cluster-store` (previously `--kv-store`) and `--cluster-advertise`. It can be used in two ways by interested components: 1. Externally by calling the `/info` API and examining the cluster store field. The `pkg/discovery` package can then be used to hit the same endpoint and watch for appearing or disappearing nodes. That is the method that will for example be used by Swarm. 2. Internally by using the `Daemon.discoveryWatcher` instance. That is the method that will for example be used by libnetwork.

The Docker daemon attempts to identify naming +conflicts but this is not guaranteed.

Just relabling -init directory in BTRFS use case. Everything looks like it works. I don't believe tar/achive stores the SELinux labels, so we are good as far as docker commit. Tested Speed on startup with BTRFS on top of loopback directory. BTRFS not on loopback should get even better perfomance on startup time. The more inodes inside of the container image will increase the relabel time. This patch will give people who care more about security the option of runnin BTRFS with SELinux.

Discovery module tracks the liveness of a node through a simple keepalive mechanism. The keepalive mechanism depends on every node performing heartbeat by registering itself with the discovery module (via KV-Store Put operation). And for every Put operation, the discovery module in all other nodes will receive a Watch notification. That keeps the node alive. Any node that fails to register itself within the TTL timer is considered dead and removed from the discovery database. The default timer (heartbeat = 20 seconds & ttl = 60 seconds) works fine for small clusters. But for large clusters, these default timers are extremely aggressive and that causes high CPU & most of the processing is spent managing the node discovery and that impacts normal daemon operation. Hence we need a way to make the discovery ttl and heartbeat configurable. As the cluster size grows, the user can change these timers to make sure the daemon scales.

They expect that the `docker top $CONT` command displays same information as the `docker exec $CONT ps -ef` command. But it does not. That's why the `docker top` man page shall explicitly state that the `docker top $CONT` displays information from the host's point of view.

The infrastructure enables registering a set of external authorization plug-in. Each plug-in receives information about the user and the request and decides whether to allow or deny the request. Only in case all plug-ins allow accessing the resource the access is granted. Each plug-in operates as a separate service, and registers with Docker through general (plug-ins API) [https://blog.docker.com/2015/06/extending-docker-with-plugins/]. No Docker daemon recompilation is required in order to add / remove an authentication plug-in. Each plug-in is notified twice for each operation: 1) before the operation is performed and, 2) before the response is returned to the client. The plug-ins can modify the response that is returned to the client. The authorization depends on the authorization effort that takes place in parallel [https://github.com/docker/docker/issues/13697]. This is the official issue of the authorization effort: https://github.com/docker/docker/issues/14674 (Here)[https://github.com/rhatdan/docker-rbac] you can find an open document that discusses a default RBAC plug-in for Docker.

Any user with +permission to access to the Docker daemon can run any Docker client command. The +same is true for callers using Docker's remote API to contact the daemon. If you +require greater access control, you can create authorization plugins and add +them to your Docker daemon configuration.

These +skills, at their most basic, are knowledge of Docker, understanding of REST, and +sound programming knowledge. This document describes the architecture, state, +and methods information available to an authorization plugin developer. ## Basic principles -* The authorization sub-system is based on Docker's [Plugin API](http://docs.docker.com/engine/extend/plugin_api), so that anyone could add / develop an authorization plug-in. It is possible to add a plug-in to a deployed Docker daemon without the need to rebuild the daemon.

You can add a plugin to a installed Docker daemon. You do +need to restart the Docker daemon to add a new plugin. -* The authorization sub-system enables approving or denying the response from the Docker daemon based on the current user and the command context. +An authorization plugin approves or denies requests to the Docker daemon based +on both the current authentication context and the command context.

Each plug-in will receive user's information (retrieved using the authentication sub-system) and HTTP request information and decide whether to allow or deny the request. Plugins can be chained together and only in case where all plug-ins allow accessing the resource, the is access granted. +You are responsible for registering your plugin as part of the Docker daemon +startup. You can install multiple plugins and chain them together. This chain +can be ordered. Each request to the daemon passes in order through the chain. +Only when all the plugins grant access to the resource, is the access granted. -Recently Docker introduced a new extendability mechanism called [plug-in infrastructure](http://docs.docker.com/engine/extend/plugin_api), which enables extending Docker by dynamically loading, removing and communicating with third-party components using a generic, easily extendable, API. The authorization sub-system was build using this mechanism. +When an HTTP request is made to the Docker daemon through the CLI or via the +remote API, the authentication subsystem passes the request to the installed +authentication plugin(s). The request contains the user (caller) and command +context. The plugin is responsible for deciding whether to allow or deny the +request. -To enable full extendability, each plugin receives the authenticated user name, the request context including the user, HTTP headers, and the request/response body. No authentication information will be passed to the authorization plug-in except for: 1) user name, and 2) authentication method that was used. Specifically, no user credentials or tokens will be passed. The request / response bodies will be sent to the plugin only in case the Content-Type is either `text/*` or `application/json`. +Below please find tow sequence diagrams describing the *allow* and *deny* +authorization flows: -For commands that involve the hijacking of the HTTP connection (HTTP Upgrade), such as `exec`, the authorization plugins will only be called for the initial HTTP requests, once the commands are approved, authorization will not be applied to the rest of the flow. Specifically, the streaming data will not be passed to the authorization plugins. For commands that return chunked HTTP response, such as `logs` and `events`, only the HTTP request will be sent to the authorization plug-ins as well. +![Bad Address](images/authz_allow.png) -During request / response processing, some authorization plugins flows might require performing additional queries to the docker daemon.

Making a volume `slave` enables only one +way mount propagation and that is mounts done on host under that volume +will be visible inside container but not the other way around. + +To control mount propagation property of volume one can use `:[r]shared`, +`:[r]slave` or `:[r]private` propagation flag. Propagation property can +be specified only for bind mounted volumes and not for internal volumes or +named volumes. For mount propagation to work source mount point (mount point +where source dir is mounted on) has to have right propagation properties. For +shared volumes, source mount point has to be shared. And for slave volumes, +source mount has to be either shared or slave. + +Use `df ` to figure out the source mount and then use +`findmnt -o TARGET,PROPAGATION ` to figure out propagation +properties of source mount.

If the last tag referencing a given image is deleted, any digest references to it will be removed as well, so the image can actually get deleted.

Libnetwork now gives users total control over both IPv4 and IPv6 adressing. The VLAN drivers build on top of that in giving operators complete control of layer 2 VLAN tagging and even Ipvlan L3 routing for users interested in underlay network integration. For overlay deployments that abstract away physical constraints see the [multi-host overlay ](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) driver. + +Macvlan and Ipvlan are a new twist on the tried and true network virtualization technique. The Linux implementations are extremely lightweight because rather then using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce seperation between networks and connectivty to the physical network. + +Macvlan and Ipvlan offer a number of unique features and plenty of room for further innovations with the various modes. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having less moving parts. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a very simple setup consisting of container interfaces, attached directly to the Docker host interface. This result is easy access for external facing services as there is no port mappings in these scenarios. + + +### Pre-Requisites + +- The examples on this page are all single host and setup using Docker experimental builds that can be installed with the following instructions: [Install Docker experimental](https://github.com/docker/docker/tree/master/experimental) + +- All of the examples can be performed on a single host running Docker. Any examples using a sub-interface like `eth0.10` can be replaced with `eth0` or any other valid parent interface on the Docker host. Sub-interfaces with a `.` are created on the fly. `-o parent` interfaces can also be left out of the `docker network create` all together and the driver will create a `dummy` interface that will enable local host connectivity to perform the examples. + +- Kernel requirements: + + - To check your current kernel version, use `uname -r` to display your kernel version + - Macvlan Linux kernel v3.9–3.19 and 4.0+ + - Ipvlan Linux kernel v4.2+ (support for earlier kernels exists but is buggy) + + +### MacVlan Bridge Mode Example Usage + +Macvlan Bridge mode has a unique MAC address per container used to track MAC to port mappings by the Docker host. This is the largest difference from Ipvlan L2 mode which uses the same MAC address as the parent interface for each container `eth0` interface. + +- Macvlan and Ipvlan driver networks are attached to a parent Docker host interface. Examples are a physical interface such as `eth0`, a sub-interface for 802.1q VLAN tagging like `eth0.10` (`.10` representing VLAN `10`) or even bonded host adaptors which bundle two Ethernet interfaces into a single logical interface. + +- The specified gateway is external to the host provided by the network infrastructure. + +- Each Macvlan Bridge mode Docker network is isolated from one another and there can be only one network attached to a parent interface at a time. There is a theoretical limit of 4,094 sub-interfaces per host adaptor that a Docker network could be attached to. + +- It is not recommended to mix ipvlan and macvlan networks on the same `-o parent=` interface. Older kernel versions will throw uninformative netlink errors such as `device is busy`. + +- Any container inside the same subnet can talk any other container in the same network without a gateway in both `macvlan bridge` mode and `ipvlan L2` modes. + +- The same `docker network` commands apply to the vlan drivers. Some are irrelevant such as `-icc` or `--set-macaddress` for the Ipvlan driver. + +- In Macvlan and Ipvlan L2 mode, containers on separate networks cannot reach one another without an external process routing between the two networks/subnets. This also applies to multiple subnets within the same `docker network`. See Ipvlan L3 mode for inter-subnet communications without a router. + +In the following example, `eth0` on the docker host has an IP on the `192.168.1.0/24` network and a default gateway of `192.168.1.1`. The gateway is an external router with an address of `192.168.1.1`. An IP address is not required on the Docker host interface `eth0` in `bridge` mode, it merely needs to be on the proper upstream network to get forwarded by a network switch or network router. + +![Simple Macvlan Bridge Mode Example](../docs/userguide/networking/../docs/userguide/networking/images/macvlan_bridge_simple.png) + + +**Note** For Macvlan bridge mode and Ipvlan L2 mode the subnet values need to match the NIC's interface of the Docker host. For example, Use the same subnet and gateway of the Docker host ethernet interface that is specified by the `-o parent=` option. + +- The parent interface used in this example is `eth0` and it is on the subnet `172.16.86.0/24`. The containers in the `docker network` will also need to be on this same subnet as the parent `-o parent=`.

The default mode for Macvlan is `bridge`. If `-o ipvlan_mode=` or `-o macvlan_mode=` are left unspecified, the default modes will be used. Similarly, if the `--gateway` is left empty, the first usable address on the network will be set as the gateway. For example, if the subnet provided in the network create is `--subnet=192.168.1.0/24` then the gateway the container receives is `192.168.1.1`. + +The following will create the exact same network as the network `db_net` created prior, with the driver defaults for `--gateway=192.168.1.1` and `-o ipvlan_mode=l2`. + +``` +# Ipvlan (-o ipvlan_mode= Defaults to L2 mode if not specified) +docker network create -d ipvlan \ + --subnet=192.168.1.0/24 \ + -o parent=eth0 db_net_ipv + +# Start a container with an explicit name in daemon mode +docker run --net=db_net_ipv --name=ipv1 -itd alpine /bin/sh + +# Start a second container and ping using the container name +# to see the docker included name resolution functionality +docker run --net=db_net_ipv --name=ipv2 -it --rm alpine /bin/sh +ping -c 4 ipv1 + +# NOTE: the containers can NOT ping the underlying host interfaces as +# they are intentionally filtered by Linux for additional isolation. +``` + +The drivers also support the `--internal` flag that will completely isolate containers on a network from any communications external to that network. Since network isolation is tightly coupled to the network's parent interface the result of leaving the `-o parent=` option off of a network create is the exact same as the `--internal` option. If the parent interface is not specified or the `--internal` flag is used, a netlink type `dummy` parent interface is created for the user and used as the parent interface effectively isolating the network completely. + +The following two `docker network create` examples result in identical networks that you can attach container to: + +``` +# Empty '-o parent=' creates an isolated network +docker network create -d ipvlan \ + --subnet=192.168.10.0/24 isolated1 + +# Explicit '--internal' flag is the same: +docker network create -d ipvlan \ + --subnet=192.168.11.0/24 --internal isolated2 + +# Even the '--subnet=' can be left empty and the default +# IPAM subnet of 172.18.0.0/16 will be assigned +docker network create -d ipvlan isolated3 + +docker run --net=isolated1 --name=cid1 -it --rm alpine /bin/sh +docker run --net=isolated2 --name=cid2 -it --rm alpine /bin/sh +docker run --net=isolated3 --name=cid3 -it --rm alpine /bin/sh + +# To attach to any use `docker exec` and start a shell +docker exec -it cid1 /bin/sh +docker exec -it cid2 /bin/sh +docker exec -it cid3 /bin/sh +``` + +### Macvlan 802.1q Trunk Bridge Mode Example Usage + +VLANs (Virtual Local Area Networks) have long been a primary means of virtualizing data center networks and are still in virtually all existing networks today. VLANs work by tagging a Layer-2 isolation domain with a 12-bit identifier ranging from 1-4094 that is inserted into a packet header that enables a logical grouping of a single or multiple subnets of both IPv4 and IPv6. It is very common for network operators to separate traffic using VLANs based on a subnet(s) function or security profile such as `web`, `db` or any other isolation needs. + +It is very common to have a compute host requirement of running multiple virtual networks concurrently on a host. Linux networking has long supported VLAN tagging, also known by it's standard 802.1q, for maintaining datapath isolation between networks. The Ethernet link connected to a Docker host can be configured to support the 802.1q VLAN IDs, by creating Linux sub-interfaces, each one dedicated to a unique VLAN ID. + +![Simple Ipvlan L2 Mode Example](../docs/userguide/networking/images/multi_tenant_8021q_vlans.png) + +Trunking 802.1q to a host is notoriously painful. It requires configuration file changes in order to be persistent through a reboot and if a bridge is involved a physical NIC needs to be moved into the bridge and the bridge then gets the IP address or risk being cut off from the network. + +Like all of the Docker network drivers, the overarching goal is to alleviate the operational pains of managing network resources. To that end, when a network receives a sub-interface as the parent that does not exist, the drivers create the VLAN tagged interfaces while creating the network. + +In the case of a host reboot, instead of needing to modify often complex network configuration files the driver will recreate all network links when the Docker daemon restarts. The driver tracks if it created the VLAN tagged sub-interface originally with the network create and will **only** recreate the sub-interface after a restart or delete `docker network rm` the link if it created it in the first place with `docker network create`. + +If the user doesn't want Docker to modify the `-o parent` sub-interface, the user simply needs to pass an existing link that already exists as the parent interface. Parent interfaces such as `eth0` are not deleted, only sub-interfaces that are not master links. + +For the driver to add/delete the vlan sub-interfaces the format needs to be `interface_name.vlan_tag`. + +For example: `eth0.50` denotes a parent interface of `eth0` with a slave of `eth0.50` tagged with vlan id `50`. The equivalent `ip link` command would be `ip link add link eth0 name eth0.50 type vlan id 50`. + +Replace the `macvlan` with `ipvlan` in the `-d` driver argument to create macvlan 802.1q trunks. + +**Vlan ID 50** + +In the first network tagged and isolated by the Docker host, `eth0.50` is the parent interface tagged with vlan id `50` specified with `-o parent=eth0.50`. Other naming formats can be used, but the links need to be added and deleted manually using `ip link` or Linux configuration files. As long as the `-o parent` exists anything can be used if compliant with Linux netlink. + +``` +# now add networks and hosts as you would normally by attaching to the master (sub)interface that is tagged +docker network create -d macvlan \ + --subnet=192.168.50.0/24 \ + --gateway=192.168.50.1 \ + -o parent=eth0.50 macvlan50 + +# In two separate terminals, start a Docker container and the containers can now ping one another. +docker run --net=macvlan50 -it --name macvlan_test5 --rm alpine /bin/sh +docker run --net=macvlan50 -it --name macvlan_test6 --rm alpine /bin/sh +``` + +**Vlan ID 60** + +In the second network, tagged and isolated by the Docker host, `eth0.60` is the parent interface tagged with vlan id `60` specified with `-o parent=eth0.60`.

There are nuances that can be advantageous for CAM table pressure in ToR switches, one MAC per port and MAC exhaustion on a host's parent NIC to name a few. The 802.1q trunk scenario looks the same. Both modes adhere to tagging standards and have seamless integration with the physical network for underlay integration and hardware vendor plugin integrations. + +![Simple Ipvlan L2 Mode Example](../docs/userguide/networking/images/multi_tenant_8021q_vlans.png) + +The Linux sub-interface tagged with a vlan can either already exist or will be created when you call a `docker network create`. `docker network rm` will delete the sub-interface. Parent interfaces such as `eth0` are not deleted, only sub-interfaces with a netlink parent index > 0. + +For the driver to add/delete the vlan sub-interfaces the format needs to be `interface_name.vlan_tag`. Other sub-interface naming can be used as the specified parent, but the link will not be deleted automatically when `docker network rm` is invoked. + +The option to use either existing parent vlan sub-interfaces or let Docker manage them enables the user to either completely manage the Linux interfaces and networking or let Docker create and delete the Vlan parent sub-interfaces (netlink `ip link`) with no effort from the user. + +For example: `eth0.10` to denote a sub-interface of `eth0` tagged with vlan id `10`. The equivalent `ip link` command would be `ip link add link eth0 name eth0.10 type vlan id 10`. + +The example creates the vlan tagged networks and then start two containers to test connectivity between containers.

In order for the `192.168.114.0/24` to reach `192.168.116.0/24` it requires an external router in L2 mode. L3 mode can route between subnets that share a common `-o parent=`. This same multi-subnet example is also valid for Macvlan `bridge` mode. + +Secondary addresses on network routers are common as an address space becomes exhausted to add another secondary to a L3 vlan interface or commonly referred to as a "switched virtual interface" (SVI). + +``` +docker network create -d ipvlan \ + --subnet=192.168.114.0/24 --subnet=192.168.116.0/24 \ + --gateway=192.168.114.254 --gateway=192.168.116.254 \ + -o parent=eth0.114 \ + -o ipvlan_mode=l2 ipvlan114 + +docker run --net=ipvlan114 --ip=192.168.114.10 -it --rm alpine /bin/sh +docker run --net=ipvlan114 --ip=192.168.114.11 -it --rm alpine /bin/sh +``` + +A key takeaway is, operators have the ability to map their physical network into their virtual network for integrating containers into their environment with no operational overhauls required. NetOps simply drops an 802.1q trunk into the Docker host. That virtual link would be the `-o parent=` passed in the network creation. For untagged (non-VLAN) links, it is as simple as `-o parent=eth0` or for 802.1q trunks with VLAN IDs each network gets mapped to the corresponding VLAN/Subnet from the network. + +An example being, NetOps provides VLAN ID and the associated subnets for VLANs being passed on the Ethernet link to the Docker host server. Those values are simply plugged into the `docker network create` commands when provisioning the Docker networks. These are persistent configurations that are applied every time the Docker engine starts which alleviates having to manage often complex configuration files. The network interfaces can also be managed manually by being pre-created and docker networking will never modify them, simply use them as parent interfaces. Example mappings from NetOps to Docker network commands are as follows: + +- VLAN: 10, Subnet: 172.16.80.0/24, Gateway: 172.16.80.1 + + - `--subnet=172.16.80.0/24 --gateway=172.16.80.1 -o parent=eth0.10` + +- VLAN: 20, IP subnet: 172.16.50.0/22, Gateway: 172.16.50.1 + + - `--subnet=172.16.50.0/22 --gateway=172.16.50.1 -o parent=eth0.20 ` + +- VLAN: 30, Subnet: 10.1.100.0/16, Gateway: 10.1.100.1 + + - `--subnet=10.1.100.0/16 --gateway=10.1.100.1 -o parent=eth0.30` + +### IPVlan L3 Mode Example + +IPVlan will require routes to be distributed to each endpoint. The driver only builds the Ipvlan L3 mode port and attaches the container to the interface. Route distribution throughout a cluster is beyond the initial implementation of this single host scoped driver. In L3 mode the Docker host is very similar to a router starting new networks in the container. They are on networks that the upstream network will not know about without route distribution. For those curious how Ipvlan L3 will fit into container networking see the following examples. + +- Ipvlan L3 mode drops all broadcast and multicast traffic. + +- L3 mode needs to be on a separate subnet as the default namespace since it requires a netlink route in the default namespace pointing to the Ipvlan parent interface. + +- The parent interface used in this example is `eth0` and it is on the subnet `192.168.1.0/24`. Notice the `docker network` is **not** on the same subnet as `eth0`. + +- Unlike macvlan bridge mode and ipvlan l2 modes, different subnets/networks can ping one another as long as they share the same parent interface `-o parent=`. + +``` +ip a show eth0 +3: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 + link/ether 00:50:56:39:45:2e brd ff:ff:ff:ff:ff:ff + inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0 +``` + +-A traditional gateway doesn't mean much to an L3 mode Ipvlan interface since there is no broadcast traffic allowed. Because of that, the container default gateway simply point the the containers `eth0` device. See below for CLI output of `ip route` or `ip -6 route` from inside an L3 container for details. + +The mode ` -o ipvlan_mode=l3` must be explicitly specified since the default ipvlan mode is `l2`. + +``` +# Create the Ipvlan L3 network +docker network create -d ipvlan \ + --subnet=192.168.214.0/24 \ + --subnet=10.1.214.0/24 \ + -o ipvlan_mode=l3 ipnet210 + +# Test 192.168.214.0/24 connectivity +docker run --net=ipnet210 --ip=192.168.214.10 -itd alpine /bin/sh +docker run --net=ipnet210 --ip=10.1.214.10 -itd alpine /bin/sh + +# Test L3 connectivity from 10.1.214.0/24 to 192.168.212.0/24 +docker run --net=ipnet210 --ip=192.168.214.9 -it --rm alpine ping -c 2 10.1.214.10 + +# Test L3 connectivity from 192.168.212.0/24 to 10.1.214.0/24 +docker run --net=ipnet210 --ip=10.1.214.9 -it --rm alpine ping -c 2 192.168.214.10 + +``` + +Notice there is no `--gateway=` option in the network create. The field is ignored if one is specified `l3` mode. Take a look at the container routing table from inside of the container: + +``` +# Inside an L3 mode container +$ ip route + default dev eth0 + 192.168.120.0/24 dev eth0 src 192.168.120.2 +``` + +In order to ping the containers from a remote Docker host or the container be able to ping a remote host, the remote host or the physical network in between need to have a route pointing to the host IP address of the container's Docker host eth interface.

Especially in case of xfs it is possible that xfs keeps on retrying IO infinitely (for certain kind of IO) and container hangs. One way to mitigate the problem is that once thin pool is about to get full, start failing some of the docker operations like pulling new images or creation of new containers. That way user will get warning ahead of time and can try to rectify it by creating more free space in thin pool. This can be done either by deleting existing images/containers or by adding more free space to thin pool. This patch adds a new option dm.min_free_space to devicemapper graph driver. Say one specifies dm.min_free_space=10%. This means atleast 10% of data and metadata blocks should be free in pool before new device creation is allowed, otherwise operation will fail. By default min_free_space is 10%. User can change it by specifying dm.min_free_space=X% on command line. A value of 0% will disable the check.

The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce seperation between networks and connectivity to the physical network. Macvlan and Ipvlan offer a number of unique features and plenty of room for further innovations with the various modes. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having less moving parts. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a very simple setup consisting of container interfaces, attached directly to the Docker host interface. This result is easy access for external facing services as there is no port mappings in these scenarios.

The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce separation between networks and connectivity to the physical network. Macvlan and Ipvlan offer a number of unique features and plenty of room for further innovations with the various modes. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having less moving parts. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a very simple setup consisting of container interfaces, attached directly to the Docker host interface. This result is easy access for external facing services as there is no port mappings in these scenarios. @@ -44,7 +44,7 @@ Macvlan Bridge mode has a unique MAC address per container used to track MAC to In the following example, `eth0` on the docker host has an IP on the `172.16.86.0/24` network and a default gateway of `172.16.86.1`.

In most scenarios, a multi-tier application is tiered into different subnets because the security profile of each process requires some form of isolation. For example, hosting your credit card processing on the same virtual network as the frontend webserver would be a regulatory compliance issue, along with circumventing the long standing best practice of layered defense in depth architectures.

This reason alone makes Ipvlan L3 mode a prime candidate for those looking for massive scale and predictable network integrations. It is predictable and in turn will lead to greater uptimes because there is no bridging involved. Bridging loops have been responsible for high profile outages that can be hard to pinpoint depending on the size of the failure domain. This is due to the cascading nature of BPDUs (Bridge Port Data Units) that are flooded throughout a broadcast domain (VLAN) to find and block topology loops. Eliminating bridging domains, or at the least, keeping them isolated to a pair of ToRs (top of rack switches) will reduce hard to troubleshoot bridging instabilities. Macvlan Bridge and Ipvlan L2 modes are well suited for isolated VLANs only trunked into a pair of ToRs that can provide a loop-free non-blocking fabric. The next step further is to route at the edge via Ipvlan L3 mode that reduces a failure domain to a local host only. - L3 mode needs to be on a separate subnet as the default namespace since it requires a netlink route in the default namespace pointing to the Ipvlan parent interface. @@ -387,6 +412,8 @@ ip a show eth0 The mode ` -o ipvlan_mode=l3` must be explicitly specified since the default ipvlan mode is `l2`. +The following example does not specify a parent interface.

To be consistent, `docker stats` needs to use BytesSize for all memory related outputs to conform to RAMInBytes in `docker run`. This fix addresses this issue. As BytesSize is used, the test cases needs to be adjusted to match `KiB/MiB/GiB` instead of `KB/MB/GB`. The documentation has also been updated. This fix fixes #21765.

It adds a `HEALTHCHECK` instruction to the Dockerfile syntax plus some corresponding "docker run" options. It can be used with a restart policy to automatically restart a container if the check fails. The `HEALTHCHECK` instruction has two forms: * `HEALTHCHECK [OPTIONS] CMD command` (check container health by running a command inside the container) * `HEALTHCHECK NONE` (disable any healthcheck inherited from the base image) The `HEALTHCHECK` instruction tells Docker how to test a container to check that it is still working. This can detect cases such as a web server that is stuck in an infinite loop and unable to handle new connections, even though the server process is still running. When a container has a healthcheck specified, it has a _health status_ in addition to its normal status. This status is initially `starting`. Whenever a health check passes, it becomes `healthy` (whatever state it was previously in). After a certain number of consecutive failures, it becomes `unhealthy`. The options that can appear before `CMD` are: * `--interval=DURATION` (default: `30s`) * `--timeout=DURATION` (default: `30s`) * `--retries=N` (default: `1`) The health check will first run **interval** seconds after the container is started, and then again **interval** seconds after each previous check completes. If a single run of the check takes longer than **timeout** seconds then the check is considered to have failed. It takes **retries** consecutive failures of the health check for the container to be considered `unhealthy`. There can only be one `HEALTHCHECK` instruction in a Dockerfile. If you list more than one then only the last `HEALTHCHECK` will take effect. The command after the `CMD` keyword can be either a shell command (e.g. `HEALTHCHECK CMD /bin/check-running`) or an _exec_ array (as with other Dockerfile commands; see e.g. `ENTRYPOINT` for details). The command's exit status indicates the health status of the container. The possible values are: - 0: success - the container is healthy and ready for use - 1: unhealthy - the container is not working correctly - 2: starting - the container is not ready for use yet, but is working correctly If the probe returns 2 ("starting") when the container has already moved out of the "starting" state then it is treated as "unhealthy" instead. For example, to check every five minutes or so that a web-server is able to serve the site's main page within three seconds: HEALTHCHECK --interval=5m --timeout=3s \ CMD curl -f http://localhost/ || exit 1 To help debug failing probes, any output text (UTF-8 encoded) that the command writes on stdout or stderr will be stored in the health status and can be queried with `docker inspect`. Such output should be kept short (only the first 4096 bytes are stored currently). When the health status of a container changes, a `health_status` event is generated with the new status. The health status is also displayed in the `docker ps` output.

From 57b18d547483b522b38610f3febbd805fde2a7c9 Mon Sep 17 00:00:00 2001 From: Yong Tang Date: Thu, 2 Jun 2016 19:54:35 -0700 Subject: [PATCH 1414/2538] Add missing links in deprecated.md doc. This fix tries to address several issues in deprecated.md: 1. For deprecated and removal versions, some include link reference to the release tag but some does not point to the release tag. This fix adds the missing links as long as the version is <= 1.12. 2. Technically, 1.12 is not released yet so the link to 1.12 does not exist yet. However, at the time 1.12 is released this deprecated.md doc should have been part of the release as well. There is a circular dependency. This fix adds 1.12 for now. 3. `HostConfig at API container start` has already been removed by #22570 so this fix changes `Target For Removal In Release: v1.12` to `Removed In Release: v1.12`. 4. `Docker search 'automated' and 'stars' options` has not been removed yet so this fix changes `Removed In Release: v1.14` to `Target For Removal In Release: v1.14` Signed-off-by: Yong Tang --- docs/deprecated.md | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-) diff --git a/docs/deprecated.md b/docs/deprecated.md index 9de65b28c2..2710a52b48 100644 --- a/docs/deprecated.md +++ b/docs/deprecated.md @@ -15,21 +15,21 @@ weight=80 The following list of features are deprecated in Engine. ### `-e` and `--email` flags on `docker login` -**Deprecated In Release: v1.11** +**Deprecated In Release: [v1.11.0](https://github.com/docker/docker/releases/tag/v1.11.0)** **Target For Removal In Release: v1.13** The docker login command is removing the ability to automatically register for an account with the target registry if the given username doesn't exist.

Since workers may sometimes receive sensitive data such as pull credentials, it makes sense to harden the defaults. This change makes `docker swarm init` generate a random secret if none is provided, and print it to the terminal. This secret will be needed to join workers or managers to the swarm. In addition to improving access control to the cluster, this setup removes an avenue for denial-of-service attacks, since the secret is necessary to even create an entry in the node list. `docker swarm init --secret ""` will set up a swarm without a secret, matching the old behavior. `docker swarm update --secret ""` removes the automatically generated secret after `docker swarm init`.

Before kernel version 4.6, kernel memory will not be accounted until kernel memory limit is set, if a container created with kernel memory initialized, kernel memory is accounted as soon as process created in container, so kernel memory limit update is allowed afterward. If kernel memory is not initialized, kernel memory consumed by processes in container will not be accounted, so we can't update the limit because the account will be wrong.

The default value for processes is 0 with a min/max of -1000/1000. -500 is a good middle ground because it is less than the default for most processes and still not -1000 which basically means never kill this process in an OOM condition on the host machine. The only processes on my machine that have a score less than -500 are dbus at -900 and sshd and xfce( my window manager ) at -1000.

This may not be enough for production environment and there is a need to extend the deprecation cycle to 3 releases (see #24494). This fix updates the docs/deprecated.md and extend the deprecation cycle to 3 releases. This fix is related to #24494 and #24534. This fix fixes #24534.

From 18cd5ac352d6dbb5d538a7bcf0e96ef160618d3b Mon Sep 17 00:00:00 2001 From: Aaron Lehmann Date: Thu, 30 Jun 2016 18:07:35 -0700 Subject: [PATCH 1608/2538] Split advertised address from listen address There are currently problems with "swarm init" and "swarm join" when an explicit --listen-addr flag is not provided. swarmkit defaults to finding the IP address associated with the default route, and in cloud setups this is often the wrong choice. Introduce a notion of "advertised address", with the client flag --advertise-addr, and the daemon flag --swarm-default-advertise-addr to provide a default. The default listening address is now 0.0.0.0, but a valid advertised address must be detected or specified. If no explicit advertised address is specified, error out if there is more than one usable candidate IP address on the system. This requires a user to explicitly choose instead of letting swarmkit make the wrong choice. For the purposes of this autodetection, we ignore certain interfaces that are unlikely to be relevant (currently docker*). The user is also required to choose a listen address on swarm init if they specify an explicit advertise address that is a hostname or an IP address that's not local to the system. This is a requirement for overlay networking. Also support specifying interface names to --listen-addr, --advertise-addr, and the daemon flag --swarm-default-advertise-addr. This will fail if the interface has multiple IP addresses (unless it has a single IPv4 address and a single IPv6 address - then we resolve the tie in favor of IPv4). This change also exposes the node's externally-reachable address in docker info, as requested by #24017. Make corresponding API and CLI docs changes.

Users can use docker service inspect --pretty servicename to see the update status, and if it pauses due to a failure, it will explain that the update is paused, and show the task ID that caused it to pause. It also shows the time since the update started. A new --update-on-failure=(pause|continue) flag selects the behavior. Pause means the update stops once a task fails, continue means the old behavior of continuing the update anyway. In the future this will be extended with additional behaviors like automatic rollback, and flags controlling parameters like how many tasks need to fail for the update to stop proceeding.

As of now xfs retries the IO and keeps on retrying and does not give up. This can result in container application being stuck for a very long time. In fact I have seen instances of unkillable processes. So that means once thin pool is full and process gets stuck, container can't be stopped/killed either and only option left seems to be power recycle of the box. In another instance, writer did not block but failed after a while. But when I tried to exit/stop the container, unmounting xfs hanged and only thing I could do was power cycle the machine. Now upstream kernel has committed patches where it allows user space to customize user space behavior in case of errors. One of the knobs is max_retries, which specifies how many times an IO should be retried when ENOSPC is encountered. This patch sets provides a tunable knob (dm.xfs_nospace_max_retries) so that user can specify value for max_retries and tune xfs behavior. If one sets this value to 0, xfs will not retry IO when ENOSPC error is encountered. It will instead give up and shutdown filesystem. This knob can be useful if one is running into unkillable processes/containers issue on top of xfs.

+| **src** | `bind` only |
  • `type=volume`: Use `src` to specify the name of the volume (e.g., `src=my-volume`). If a volume with the given name does not exist, it is automatically created. If this option is omitted, an ephemeral volume with a random name is generated. Random names are guaranteed to be unique on the host, but may not be unique cluster-wide. Ephemeral volumes have the same lifecycle as the container it is attached to, and are destroyed when the *container* is destroyed (which is upon `service update`, or when scaling or re-balancing the service).
  • `type=bind`: Use `src` to specify host-path to bind mount (e.g., `src=/path/on/host/`). When using a bind-mount (`"type=bind"`), the `src` path must be specified as an absolute path, and *must* be a pre-existing path, or an error is produced.

Pass the `readonly` option to mount the bind or volume `read-only` in the container.

A value is optional:

VLANs work by tagging a Layer-2 isolation domain with a 12-bit identifier ranging from 1-4094 that is inserted into a packet header that enables a logical grouping of a single or multiple subnets of both IPv4 and IPv6. It is very common for network operators to separate traffic using VLANs based on a subnet(s) function or security profile such as `web`, `db` or any other isolation needs. - -It is very common to have a compute host requirement of running multiple virtual networks concurrently on a host. Linux networking has long supported VLAN tagging, also known by its standard 802.1q, for maintaining datapath isolation between networks.

To that end, when a network receives a sub-interface as the parent that does not exist, the drivers create the VLAN tagged interfaces while creating the network. - -In the case of a host reboot, instead of needing to modify often complex network configuration files the driver will recreate all network links when the Docker daemon restarts. The driver tracks if it created the VLAN tagged sub-interface originally with the network create and will **only** recreate the sub-interface after a restart or delete `docker network rm` the link if it created it in the first place with `docker network create`. - -If the user doesn't want Docker to modify the `-o parent` sub-interface, the user simply needs to pass an existing link that already exists as the parent interface.

The guide explains in -detail, with examples, how to contribute. If you are an experienced contributor -this quickstart should be enough to get you started. - -The following is the essential workflow for contributing to the documentation: - -1. Fork the `docker/docker` repository. - -2. Clone the repository to your local machine. - -3. Select an issue from `docker/docker` to work on or submit a proposal of your -own. - -4. Create a feature branch from `master` in which to work. - - By basing from `master` your work is automatically included in the next - release. It also allows docs maintainers to easily cherry-pick your changes - into the `docs` release branch. - -4. Modify existing or add new `.md` files to the `docs` directory. - -5. As you work, build the documentation site locally to see your changes. - - The `docker/docker` repository contains a `Dockerfile` and a `Makefile`. - Together, these create a development environment in which you can build and - run a container running the Docker documentation website. To build the - documentation site, enter `make docs` in the `docs` directory of your `docker/docker` fork: - - $ make docs - .... (lots of output) .... - docker run --rm -it -e AWS_S3_BUCKET -p 8000:8000 "docker-docs:master" mkdocs serve - Running at: http://0.0.0.0:8000/ - Live reload enabled. - Hold ctrl+c to quit. - - - The build creates an image containing all the required tools, adds the local - `docs/` directory and generates the HTML files. Then, it runs a Docker - container with this image. - - The container exposes port 8000 on the localhost so that you can connect and - see your changes. If you use Docker Machine, the `docker-machine ip - ` command gives you the address of your server. - -6. Check your writing for style and mechanical errors. - - Use our [documentation style - guide](https://docs.docker.com/opensource/doc-style/) to check style. There are - several [good grammar and spelling online - checkers](http://www.hemingwayapp.com/) that can check your writing - mechanics. - -7. Squash your commits on your branch. - -8. Make a pull request from your fork back to Docker's `master` branch. - -9. Work with the reviewers until your change is approved and merged. - -### Debugging and testing - -If you have any issues you need to debug, you can use `make docs-shell` and then -run `mkdocs serve`. You can use `make docs-test` to generate a report of missing -links that are referenced in the documentation—there should be none. - -## Style guide - -If you have questions about how to write for Docker's documentation, please see -the [style guide](https://docs.docker.com/opensource/doc-style/). The style guide provides -guidance about grammar, syntax, formatting, styling, language, or tone. If -something isn't clear in the guide, please submit an issue to let us know or -submit a pull request to help us improve it. - - -## Publishing documentation (for Docker maintainers) - -To publish Docker's documentation you need to have Docker up and running on your -machine. You'll also need a `docs/awsconfig` file containing the settings you -need to access the AWS bucket you'll be deploying to. - -The process for publishing is to build first to an AWS bucket, verify the build, -and then publish the final release. - -1. Have Docker installed and running on your machine. - -2. Ask the core maintainers for the `awsconfig` file. - -3. Copy the `awsconfig` file to the `docs/` directory. - - The `awsconfig` file contains the profiles of the S3 buckets for our - documentation sites. (If needed, the release script creates an S3 bucket and - pushes the files to it.) Each profile has this format: - - [profile dowideit-docs] - aws_access_key_id = IHOIUAHSIDH234rwf.... - aws_secret_access_key = OIUYSADJHLKUHQWIUHE...... - region = ap-southeast-2 - - The `profile` name must be the same as the name of the bucket you are - deploying to. - -4. Call the `make` from the `docker` directory. - - $ make AWS_S3_BUCKET=dowideit-docs docs-release - - This publishes _only_ to the `http://bucket-url/v1.2/` version of the - documentation. - -5. If you're publishing the current release's documentation, you need to also -update the root docs pages by running - - $ make AWS_S3_BUCKET=dowideit-docs BUILD_ROOT=yes docs-release - -### Errors publishing using a Docker Machine VM - -Sometimes, in a Windows or Mac environment, the publishing procedure returns this -error: - - Post http:///var/run/docker.sock/build?rm=1&t=docker-docs%3Apost-1.2.0-docs_update-2: - dial unix /var/run/docker.sock: no such file or directory. - -If this happens, set the Docker host. Run the following command to get the -variables in your shell: - - docker-machine env - -Then, set your environment accordingly. - -## Cherry-picking documentation changes to update an existing release. - -Whenever the core team makes a release, they publish the documentation based on -the `release` branch. At that time, the `release` branch is copied into the -`docs` branch. The documentation team makes updates between Docker releases by -cherry-picking changes from `master` into any of the documentation branches. -Typically, we cherry-pick into the `docs` branch. - -For example, to update the current release's docs, do the following: - -1. Go to your `docker/docker` fork and get the latest from master. - - $ git fetch upstream - -2. Checkout a new branch based on `upstream/docs`. - - You should give your new branch a descriptive name. - - $ git checkout -b post-1.2.0-docs-update-1 upstream/docs - -3. In a browser window, open [https://github.com/docker/docker/commits/master]. - -4. Locate the merges you want to publish. - - You should only cherry-pick individual commits; do not cherry-pick merge - commits. To minimize merge conflicts, start with the oldest commit and work - your way forward in time. - -5. Copy the commit SHA from GitHub. - -6. Cherry-pick the commit. - - $ git cherry-pick -x fe845c4 - -7. Repeat until you have cherry-picked everything you want to merge. - -8. Push your changes to your fork. - - $ git push origin post-1.2.0-docs-update-1 - -9. Make a pull request to merge into the `docs` branch. - - Do __NOT__ merge into `master`. - -10. Have maintainers review your pull request. - -11. Once the PR has the needed "LGTMs", merge it on GitHub. - -12. Return to your local fork and make sure you are still on the `docs` branch. - - $ git checkout docs - -13. Fetch your merged pull request from `docs`. - - $ git fetch upstream/docs - -14. Ensure your branch is clean and set to the latest. - - $ git reset --hard upstream/docs - -15. Copy the `awsconfig` file into the `docs` directory. - -16.

Nor will `docker` generate an error if the `-f` flag is missing and the specified tag is already in use. - -### HostConfig at API container start -**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)** - -**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -Passing an `HostConfig` to `POST /containers/{name}/start` is deprecated in favor of -defining it at container creation (`POST /containers/create`). - -### Docker ps 'before' and 'since' options - -**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)** - -**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -The `docker ps --before` and `docker ps --since` options are deprecated. -Use `docker ps --filter=before=...` and `docker ps --filter=since=...` instead. - -### Docker search 'automated' and 'stars' options - -**Deprecated in Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -**Target For Removal In Release: v1.15** - -The `docker search --automated` and `docker search --stars` options are deprecated. -Use `docker search --filter=is-automated=...` and `docker search --filter=stars=...` instead. - -### Driver Specific Log Tags -**Deprecated In Release: [v1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0)** - -**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -Log tags are now generated in a standard way across different logging drivers. -Because of which, the driver specific log tag options `syslog-tag`, `gelf-tag` and -`fluentd-tag` have been deprecated in favor of the generic `tag` option. - - docker --log-driver=syslog --log-opt tag="{{.ImageName}}/{{.Name}}/{{.ID}}" - -### LXC built-in exec driver -**Deprecated In Release: [v1.8.0](https://github.com/docker/docker/releases/tag/v1.8.0)** - -**Removed In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)** - -The built-in LXC execution driver, the lxc-conf flag, and API fields have been removed. - -### Old Command Line Options -**Deprecated In Release: [v1.8.0](https://github.com/docker/docker/releases/tag/v1.8.0)** - -**Removed In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)** - -The flags `-d` and `--daemon` are deprecated in favor of the `daemon` subcommand: - - docker daemon -H ... - -The following single-dash (`-opt`) variant of certain command line options -are deprecated and replaced with double-dash options (`--opt`): - - docker attach -nostdin - docker attach -sig-proxy - docker build -no-cache - docker build -rm - docker commit -author - docker commit -run - docker events -since - docker history -notrunc - docker images -notrunc - docker inspect -format - docker ps -beforeId - docker ps -notrunc - docker ps -sinceId - docker rm -link - docker run -cidfile - docker run -dns - docker run -entrypoint - docker run -expose - docker run -link - docker run -lxc-conf - docker run -n - docker run -privileged - docker run -volumes-from - docker search -notrunc - docker search -stars - docker search -t - docker search -trusted - docker tag -force - -The following double-dash options are deprecated and have no replacement: - - docker run --cpuset - docker run --networking - docker ps --since-id - docker ps --before-id - docker search --trusted - -**Deprecated In Release: [v1.5.0](https://github.com/docker/docker/releases/tag/v1.5.0)** - -**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -The single-dash (`-help`) was removed, in favor of the double-dash `--help` - - docker -help - docker [COMMAND] -help - -### `--run` flag on docker commit - -**Deprecated In Release: [v0.10.0](https://github.com/docker/docker/releases/tag/v0.10.0)** - -**Removed In Release: [v1.13.0](https://github.com/docker/docker/releases/)** - -The flag `--run` of the docker commit (and its short version `-run`) were deprecated in favor -of the `--changes` flag that allows to pass `Dockerfile` commands. - - -### Interacting with V1 registries - -Version 1.9 adds a flag (`--disable-legacy-registry=false`) which prevents the docker daemon from `pull`, `push`, and `login` operations against v1 registries. Though disabled by default, this signals the intent to deprecate the v1 protocol. - -### Docker Content Trust ENV passphrase variables name change -**Deprecated In Release: [v1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0)** - -**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)** - -Since 1.9, Docker Content Trust Offline key has been renamed to Root key and the Tagging key has been renamed to Repository key. Due to this renaming, we're also changing the corresponding environment variables - -- DOCKER_CONTENT_TRUST_OFFLINE_PASSPHRASE is now named DOCKER_CONTENT_TRUST_ROOT_PASSPHRASE -- DOCKER_CONTENT_TRUST_TAGGING_PASSPHRASE is now named DOCKER_CONTENT_TRUST_REPOSITORY_PASSPHRASE - -### `MAINTAINER` in Dockerfile -**Deprecated In Release: v1.13.0** - -`MAINTAINER` was an early very limited form of `LABEL` which should be used instead. diff --git a/docs/extend/images/authz_additional_info.png b/docs/extend/images/authz_additional_info.png deleted file mode 100644 index

managed plugin system - -This document describes the plugin system available today in the **experimental -build** of Docker 1.12: - -* [How to operate an existing plugin](#how-to-operate-a-plugin) -* [How to develop a plugin](#how-to-develop-a-plugin) - -Unlike the legacy plugin system, you now manage plugins using Docker Engine: - -* install plugins -* start plugins -* stop plugins -* remove plugins - -The current Docker Engine plugin system only supports volume drivers. We are -adding more plugin driver types in the future releases. - -For information on Docker Engine plugins generally available in Docker Engine -1.12 and earlier, refer to [Understand legacy Docker Engine plugins](legacy_plugins.md). - -## How to operate a plugin - -Plugins are distributed as Docker images, so develpers can host them on Docker -Hub or on a private registry. - -You install the plugin using a single command: `docker plugin install `. -The `plugin install` command pulls the plugin from the Docker Hub or private -registry. If necessary the CLI prompts you to accept any privilige requriements. -For example the plugin may require access to a device on the host system. -Finally it enables the plugin. - -Run `docker plugin ls` to check the status of installed plugins. The Engine -markes plugins that are started without issues as `ENABLED`. - -After you install a plugin, the plugin behavior is the same as legacy plugins. -The following example demonstrates how to install the `sshfs` plugin and use it -to create a volume. - -1. Install the `sshfs` plugin. - - ```bash - $ docker plugin install vieux/sshfs - - Plugin "vieux/sshfs" is requesting the following privileges: - - network: [host] - - capabilities: [CAP_SYS_ADMIN] - Do you grant the above permissions? [y/N] y - - vieux/sshfs - ``` - - The plugin requests 2 privileges, the `CAP_SYS_ADMIN` capability to be able - to do mount inside the plugin and `host networking`. - -2. Check for a value of `true` the `ENABLED` column to verify the plugin -started without error. - - ```bash - $ docker plugin ls - - NAME TAG ENABLED - vieux/sshfs latest true - ``` - -3. Create a volume using the plugin. - - ```bash - $ docker volume create \ - -d vieux/sshfs \ - --name sshvolume \ - -o sshcmd=user@1.2.3.4:/remote - - sshvolume - ``` - -4. Use the volume `sshvolume`. - - ```bash - $ docker run -v sshvolume:/data busybox ls /data - - - ``` - -5. Verify the plugin successfully created the volume. - - ```bash - $ docker volume ls - - DRIVER NAME - vieux/sshfs sshvolume - ``` - - You can stop a plugin with the `docker plugin disable` - command or remove a plugin with `docker plugin remove`. - -See the [command line reference](../reference/commandline/index.md) for more -information. - -## How to develop a plugin - -Plugin creation is currently a manual process. We plan to add automation in a -future release with a command such as `docker plugin build`. - -This section describes the format of an existing enabled plugin. You have to -create and format the plugin files by hand. - -Plugins are stored in `/var/lib/docker/plugins`. For instance: - -```bash -# ls -la /var/lib/docker/plugins -total 20 -drwx------ 4 root root 4096 Aug 8 18:03 . -drwx--x--x 12 root root 4096 Aug 8 17:53 .. -drwxr-xr-x 3 root root 4096 Aug 8 17:56 cd851ce43a403 --rw------- 1 root root 2107 Aug 8 18:03 plugins.json -``` - -`plugins.json` is an inventory of all installed plugins. For example: - -```bash -# cat plugins.json -{ - "cd851ce43a403": { - "plugin": { - "Manifest": { - "Args": { - "Value": null, - "Settable": null, - "Description": "", - "Name": "" - }, - "Env": null, - "Devices": null, - "Mounts": null, - "Capabilities": [ - "CAP_SYS_ADMIN" - ], - "ManifestVersion": "v0", - "Description": "sshFS plugin for Docker", - "Documentation": "https://docs.docker.com/engine/extend/plugins/", - "Interface": { - "Socket": "sshfs.sock", - "Types": [ - "docker.volumedriver/1.0" - ] - }, - "Entrypoint": [ - "/go/bin/docker-volume-sshfs" - ], - "Workdir": "", - "User": {}, - "Network": { - "Type": "host" - } - }, - "Config": { - "Devices": null, - "Args": null, - "Env": [], - "Mounts": [] - }, - "Active": true, - "Tag": "latest", - "Name": "vieux/sshfs", - "Id": "cd851ce43a403" - } - } -} -``` - -Each folder represents a plugin. For example: - -```bash -# ls -la /var/lib/docker/plugins/cd851ce43a403 -total 12 -drwx------ 19 root root 4096 Aug 8 17:56 rootfs --rw-r--r-- 1 root root 50 Aug 8 17:56 plugin-config.json --rw------- 1 root root 347 Aug 8 17:56 manifest.json -``` - -`rootfs` represents the root filesystem of the plugin. In this example, it was -created from a Dockerfile as follows: - ->**Note:** `/run/docker/plugins` is mandatory for docker to communicate with -the plugin._ - -```bash -$ git clone https://github.com/vieux/docker-volume-sshfs -$ cd docker-volume-sshfs -$ docker build -t rootfs . -$ id=$(docker create rootfs true) # id was cd851ce43a403 when the image was created -$ mkdir -p /var/lib/docker/plugins/$id/rootfs -$ docker export "$id" | tar -x -C /var/lib/docker/plugins/$id/rootfs -$ docker rm -vf "$id" -$ docker rmi rootfs -``` - -`manifest.json` describes the plugin and `plugin-config.json` contains some -runtime parameters. [See the Plugins Manifest reference](manifest.md). For example: - -```bash -# cat manifest.json -{ - "manifestVersion": "v0", - "description": "sshFS plugin for Docker", - "documentation": "https://docs.docker.com/engine/extend/plugins/", - "entrypoint": ["/go/bin/docker-volume-sshfs"], - "network": { - "type": "host" - }, - "interface" : { - "types": ["docker.volumedriver/1.0"], - "socket": "sshfs.sock" - }, - "capabilities": ["CAP_SYS_ADMIN"] -} -``` - -In this example, you can see the plugin is a volume driver, requires the -`CAP_SYS_ADMIN` capability, `host networking`, `/go/bin/docker-volume-sshfs` as -entrypoint and is going to use `/run/docker/plugins/sshfs.sock` to communicate -with the Docker Engine. - -```bash -# cat plugin-config.json -{ - "Devices": null, - "Args": null, - "Env": [], - "Mounts": [] -} -``` - -This plugin doesn't require runtime parameters. - -Both `manifest.json` and `plugin-config.json` are part of the `plugins.json`. -`manifest.json` is read-only and `plugin-config.json` is read-write. - -To summarize, follow the steps below to create a plugin: - -0. Choose a name for the plugin. Plugin name uses the same format as images, -for example: `/`. -1. Create a rootfs in `/var/lib/docker/plugins/$id/rootfs`. -2. Create manifest.json file in `/var/lib/docker/plugins/$id/`. -3. Create a `plugin-config.json` if needed. -4. Create or add a section to `/var/lib/docker/plugins/plugins.json`. Use - `/` as “Name” and `$id` as “Id”. -5. Restart the Docker Engine. -6. Run `docker plugin ls`. - * If your plugin is listed as `ENABLED=true`, you can push it to the - registry. - * If the plugin is not listed or if `ENABLED=false`, something went wrong. - Check the daemon logs for errors. -7. If you are not already logged in, use `docker login` to authenticate against - a registry. -8. Run `docker plugin push /` to push the plugin. diff --git a/docs/extend/legacy_plugins.md b/docs/extend/legacy_plugins.md deleted file mode 100644 index aa4fa4a9b3..0000000000 --- a/docs/extend/legacy_plugins.md +++ /dev/null @@ -1,93 +0,0 @@ - - -# Use Docker Engine plugins - -This document describes the Docker Engine plugins generally available in Docker -Engine.

Currently running them outside -containers is recommended. - -## Plugin discovery - -Docker discovers plugins by looking for them in the plugin directory whenever a -user or container tries to use one by name. - -There are three types of files which can be put in the plugin directory. - -* `.sock` files are UNIX domain sockets. -* `.spec` files are text files containing a URL, such as `unix:///other.sock` or `tcp://localhost:8080`. -* `.json` files are text files containing a full json specification for the plugin. - -Plugins with UNIX domain socket files must run on the same docker host, whereas -plugins with spec or json files can run on a different host if a remote URL is specified. - -UNIX domain socket files must be located under `/run/docker/plugins`, whereas -spec files can be located either under `/etc/docker/plugins` or `/usr/lib/docker/plugins`. - -The name of the file (excluding the extension) determines the plugin name. - -For example, the `flocker` plugin might create a UNIX socket at -`/run/docker/plugins/flocker.sock`. - -You can define each plugin into a separated subdirectory if you want to isolate definitions from each other. -For example, you can create the `flocker` socket under `/run/docker/plugins/flocker/flocker.sock` and only -mount `/run/docker/plugins/flocker` inside the `flocker` container. - -Docker always searches for unix sockets in `/run/docker/plugins` first. It checks for spec or json files under -`/etc/docker/plugins` and `/usr/lib/docker/plugins` if the socket doesn't exist. The directory scan stops as -soon as it finds the first plugin definition with the given name. - -### JSON specification - -This is the JSON format for a plugin: - -```json -{ - "Name": "plugin-example", - "Addr": "https://example.com/docker/plugin", - "TLSConfig": { - "InsecureSkipVerify": false, - "CAFile": "/usr/shared/docker/certs/example-ca.pem", - "CertFile": "/usr/shared/docker/certs/example-cert.pem", - "KeyFile": "/usr/shared/docker/certs/example-key.pem", - } -} -``` - -The `TLSConfig` field is optional and TLS will only be verified if this configuration is present. - -## Plugin lifecycle - -Plugins should be started before Docker, and stopped after Docker. For -example, when packaging a plugin for a platform which supports `systemd`, you -might use [`systemd` dependencies]( -http://www.freedesktop.org/software/systemd/man/systemd.unit.html#Before=) to -manage startup and shutdown order. - -When upgrading a plugin, you should first stop the Docker daemon, upgrade the -plugin, then start Docker again. - -## Plugin activation - -When a plugin is first referred to -- either by a user referring to it by name -(e.g. `docker run --volume-driver=foo`) or a container already configured to -use a plugin being started -- Docker looks for the named plugin in the plugin -directory and activates it with a handshake. See Handshake API below. - -Plugins are *not* activated automatically at Docker daemon startup. Rather, -they are activated only lazily, or on-demand, when they are needed. - -## Systemd socket activation - -Plugins may also be socket activated by `systemd`. The official [Plugins helpers](https://github.com/docker/go-plugins-helpers) -natively supports socket activation. In order for a plugin to be socket activated it needs -a `service` file and a `socket` file. - -The `service` file (for example `/lib/systemd/system/your-plugin.service`): - -``` -[Unit] -Description=Your plugin -Before=docker.service -After=network.target your-plugin.socket -Requires=your-plugin.socket docker.service - -[Service] -ExecStart=/usr/lib/docker/your-plugin - -[Install] -WantedBy=multi-user.target -``` -The `socket` file (for example `/lib/systemd/system/your-plugin.socket`): -``` -[Unit] -Description=Your plugin - -[Socket] -ListenStream=/run/docker/plugins/your-plugin.sock - -[Install] -WantedBy=sockets.target -``` - -This will allow plugins to be actually started when the Docker daemon connects to -the sockets they're listening on (for instance the first time the daemon uses them -or if one of the plugin goes down accidentally). - -## API design - -The Plugin API is RPC-style JSON over HTTP, much like webhooks. - -Requests flow *from* the Docker daemon *to* the plugin. So the plugin needs to -implement an HTTP server and bind this to the UNIX socket mentioned in the -"plugin discovery" section. - -All requests are HTTP `POST` requests. - -The API is versioned via an Accept header, which currently is always set to -`application/vnd.docker.plugins.v1+json`. - -## Handshake API - -Plugins are activated via the following "handshake" API call. - -### /Plugin.Activate - -**Request:** empty body - -**Response:** -``` -{ - "Implements": ["VolumeDriver"] -} -``` - -Responds with a list of Docker subsystems which this plugin implements. -After activation, the plugin will then be sent events from this subsystem. - -Possible values are: - -* [`authz`](plugins_authorization.md) -* [`NetworkDriver`](plugins_network.md) -* [`VolumeDriver`](plugins_volume.md) - - -## Plugin retries - -Attempts to call a method on a plugin are retried with an exponential backoff -for up to 30 seconds. This may help when packaging plugins as containers, since -it gives plugin containers a chance to start up before failing any user -containers which depend on them. - -## Plugins helpers - -To ease plugins development, we're providing an `sdk` for each kind of plugins -currently supported by Docker at [docker/go-plugins-helpers](https://github.com/docker/go-plugins-helpers). diff --git a/docs/extend/plugins_authorization.md b/docs/extend/plugins_authorization.md deleted file mode 100644 index 2c3d79e25d..0000000000 --- a/docs/extend/plugins_authorization.md +++ /dev/null @@ -1,256 +0,0 @@ - - - -# Create an authorization plugin - -This document describes the Docker Engine plugins generally available in Docker -Engine. To view information on plugins managed by Docker Engine currently in -experimental status, refer to [Docker Engine plugin system](index.md). - -Docker's out-of-the-box authorization model is all or nothing. Any user with -permission to access the Docker daemon can run any Docker client command. The -same is true for callers using Docker's remote API to contact the daemon. If you -require greater access control, you can create authorization plugins and add -them to your Docker daemon configuration.

These -skills, at their most basic, are knowledge of Docker, understanding of REST, and -sound programming knowledge. This document describes the architecture, state, -and methods information available to an authorization plugin developer. - -## Basic principles - -Docker's [plugin infrastructure](plugin_api.md) enables -extending Docker by loading, removing and communicating with -third-party components using a generic API. The access authorization subsystem -was built using this mechanism. - -Using this subsystem, you don't need to rebuild the Docker daemon to add an -authorization plugin. You can add a plugin to an installed Docker daemon. You do -need to restart the Docker daemon to add a new plugin. - -An authorization plugin approves or denies requests to the Docker daemon based -on both the current authentication context and the command context. The -authentication context contains all user details and the authentication method. -The command context contains all the relevant request data. - -Authorization plugins must follow the rules described in [Docker Plugin API](plugin_api.md). -Each plugin must reside within directories described under the -[Plugin discovery](plugin_api.md#plugin-discovery) section. - -**Note**: the abbreviations `AuthZ` and `AuthN` mean authorization and authentication -respectively. - -## Default user authorization mechanism - -If TLS is enabled in the [Docker daemon](../security/https.md), the default user authorization flow extracts the user details from the certificate subject name. -That is, the `User` field is set to the client certificate subject common name, and the `AuthenticationMethod` field is set to `TLS`. - -## Basic architecture - -You are responsible for registering your plugin as part of the Docker daemon -startup. You can install multiple plugins and chain them together. This chain -can be ordered. Each request to the daemon passes in order through the chain. -Only when all the plugins grant access to the resource, is the access granted. - -When an HTTP request is made to the Docker daemon through the CLI or via the -remote API, the authentication subsystem passes the request to the installed -authentication plugin(s). The request contains the user (caller) and command -context. The plugin is responsible for deciding whether to allow or deny the -request. - -The sequence diagrams below depict an allow and deny authorization flow: - -![Authorization Allow flow](images/authz_allow.png) - -![Authorization Deny flow](images/authz_deny.png) - -Each request sent to the plugin includes the authenticated user, the HTTP -headers, and the request/response body. Only the user name and the -authentication method used are passed to the plugin. Most importantly, no user -credentials or tokens are passed. Finally, not all request/response bodies -are sent to the authorization plugin. Only those request/response bodies where -the `Content-Type` is either `text/*` or `application/json` are sent. - -For commands that can potentially hijack the HTTP connection (`HTTP -Upgrade`), such as `exec`, the authorization plugin is only called for the -initial HTTP requests. Once the plugin approves the command, authorization is -not applied to the rest of the flow. Specifically, the streaming data is not -passed to the authorization plugins. For commands that return chunked HTTP -response, such as `logs` and `events`, only the HTTP request is sent to the -authorization plugins. - -During request/response processing, some authorization flows might -need to do additional queries to the Docker daemon. To complete such flows, -plugins can call the daemon API similar to a regular user. To enable these -additional queries, the plugin must provide the means for an administrator to -configure proper authentication and security policies. - -## Docker client flows - -To enable and configure the authorization plugin, the plugin developer must -support the Docker client interactions detailed in this section. - -### Setting up Docker daemon - -Enable the authorization plugin with a dedicated command line flag in the -`--authorization-plugin=PLUGIN_ID` format.

managed plugin system + +This document describes the plugin system available today in the **experimental +build** of Docker 1.12: + +* [How to operate an existing plugin](#how-to-operate-a-plugin) +* [How to develop a plugin](#how-to-develop-a-plugin) + +Unlike the legacy plugin system, you now manage plugins using Docker Engine: + +* install plugins +* start plugins +* stop plugins +* remove plugins + +The current Docker Engine plugin system only supports volume drivers. We are +adding more plugin driver types in the future releases. + +For information on Docker Engine plugins generally available in Docker Engine +1.12 and earlier, refer to [Understand legacy Docker Engine plugins](legacy_plugins.md). + +## How to operate a plugin + +Plugins are distributed as Docker images, so develpers can host them on Docker +Hub or on a private registry. + +You install the plugin using a single command: `docker plugin install `. +The `plugin install` command pulls the plugin from the Docker Hub or private +registry. If necessary the CLI prompts you to accept any privilige requriements. +For example the plugin may require access to a device on the host system. +Finally it enables the plugin. + +Run `docker plugin ls` to check the status of installed plugins. The Engine +markes plugins that are started without issues as `ENABLED`. + +After you install a plugin, the plugin behavior is the same as legacy plugins. +The following example demonstrates how to install the `sshfs` plugin and use it +to create a volume. + +1. Install the `sshfs` plugin. + + ```bash + $ docker plugin install vieux/sshfs + + Plugin "vieux/sshfs" is requesting the following privileges: + - network: [host] + - capabilities: [CAP_SYS_ADMIN] + Do you grant the above permissions? [y/N] y + + vieux/sshfs + ``` + + The plugin requests 2 privileges, the `CAP_SYS_ADMIN` capability to be able + to do mount inside the plugin and `host networking`. + +2. Check for a value of `true` the `ENABLED` column to verify the plugin +started without error. + + ```bash + $ docker plugin ls + + NAME TAG ENABLED + vieux/sshfs latest true + ``` + +3. Create a volume using the plugin. + + ```bash + $ docker volume create \ + -d vieux/sshfs \ + --name sshvolume \ + -o sshcmd=user@1.2.3.4:/remote + + sshvolume + ``` + +4. Use the volume `sshvolume`. + + ```bash + $ docker run -v sshvolume:/data busybox ls /data + + + ``` + +5. Verify the plugin successfully created the volume. + + ```bash + $ docker volume ls + + DRIVER NAME + vieux/sshfs sshvolume + ``` + + You can stop a plugin with the `docker plugin disable` + command or remove a plugin with `docker plugin remove`. + +See the [command line reference](../reference/commandline/index.md) for more +information. + +## How to develop a plugin + +Plugin creation is currently a manual process. We plan to add automation in a +future release with a command such as `docker plugin build`. + +This section describes the format of an existing enabled plugin. You have to +create and format the plugin files by hand. + +Plugins are stored in `/var/lib/docker/plugins`. For instance: + +```bash +# ls -la /var/lib/docker/plugins +total 20 +drwx------ 4 root root 4096 Aug 8 18:03 . +drwx--x--x 12 root root 4096 Aug 8 17:53 .. +drwxr-xr-x 3 root root 4096 Aug 8 17:56 cd851ce43a403 +-rw------- 1 root root 2107 Aug 8 18:03 plugins.json +``` + +`plugins.json` is an inventory of all installed plugins. For example: + +```bash +# cat plugins.json +{ + "cd851ce43a403": { + "plugin": { + "Manifest": { + "Args": { + "Value": null, + "Settable": null, + "Description": "", + "Name": "" + }, + "Env": null, + "Devices": null, + "Mounts": null, + "Capabilities": [ + "CAP_SYS_ADMIN" + ], + "ManifestVersion": "v0", + "Description": "sshFS plugin for Docker", + "Documentation": "https://docs.docker.com/engine/extend/plugins/", + "Interface": { + "Socket": "sshfs.sock", + "Types": [ + "docker.volumedriver/1.0" + ] + }, + "Entrypoint": [ + "/go/bin/docker-volume-sshfs" + ], + "Workdir": "", + "User": {}, + "Network": { + "Type": "host" + } + }, + "Config": { + "Devices": null, + "Args": null, + "Env": [], + "Mounts": [] + }, + "Active": true, + "Tag": "latest", + "Name": "vieux/sshfs", + "Id": "cd851ce43a403" + } + } +} +``` + +Each folder represents a plugin. For example: + +```bash +# ls -la /var/lib/docker/plugins/cd851ce43a403 +total 12 +drwx------ 19 root root 4096 Aug 8 17:56 rootfs +-rw-r--r-- 1 root root 50 Aug 8 17:56 plugin-config.json +-rw------- 1 root root 347 Aug 8 17:56 manifest.json +``` + +`rootfs` represents the root filesystem of the plugin. In this example, it was +created from a Dockerfile as follows: + +>**Note:** `/run/docker/plugins` is mandatory for docker to communicate with +the plugin._ + +```bash +$ git clone https://github.com/vieux/docker-volume-sshfs +$ cd docker-volume-sshfs +$ docker build -t rootfs . +$ id=$(docker create rootfs true) # id was cd851ce43a403 when the image was created +$ mkdir -p /var/lib/docker/plugins/$id/rootfs +$ docker export "$id" | tar -x -C /var/lib/docker/plugins/$id/rootfs +$ docker rm -vf "$id" +$ docker rmi rootfs +``` + +`manifest.json` describes the plugin and `plugin-config.json` contains some +runtime parameters. [See the Plugins Manifest reference](manifest.md). For example: + +```bash +# cat manifest.json +{ + "manifestVersion": "v0", + "description": "sshFS plugin for Docker", + "documentation": "https://docs.docker.com/engine/extend/plugins/", + "entrypoint": ["/go/bin/docker-volume-sshfs"], + "network": { + "type": "host" + }, + "interface" : { + "types": ["docker.volumedriver/1.0"], + "socket": "sshfs.sock" + }, + "capabilities": ["CAP_SYS_ADMIN"] +} +``` + +In this example, you can see the plugin is a volume driver, requires the +`CAP_SYS_ADMIN` capability, `host networking`, `/go/bin/docker-volume-sshfs` as +entrypoint and is going to use `/run/docker/plugins/sshfs.sock` to communicate +with the Docker Engine. + +```bash +# cat plugin-config.json +{ + "Devices": null, + "Args": null, + "Env": [], + "Mounts": [] +} +``` + +This plugin doesn't require runtime parameters. + +Both `manifest.json` and `plugin-config.json` are part of the `plugins.json`. +`manifest.json` is read-only and `plugin-config.json` is read-write. + +To summarize, follow the steps below to create a plugin: + +0. Choose a name for the plugin. Plugin name uses the same format as images, +for example: `/`. +1. Create a rootfs in `/var/lib/docker/plugins/$id/rootfs`. +2. Create manifest.json file in `/var/lib/docker/plugins/$id/`. +3. Create a `plugin-config.json` if needed. +4. Create or add a section to `/var/lib/docker/plugins/plugins.json`. Use + `/` as “Name” and `$id` as “Id”. +5. Restart the Docker Engine. +6. Run `docker plugin ls`. + * If your plugin is listed as `ENABLED=true`, you can push it to the + registry. + * If the plugin is not listed or if `ENABLED=false`, something went wrong. + Check the daemon logs for errors. +7. If you are not already logged in, use `docker login` to authenticate against + a registry. +8. Run `docker plugin push /` to push the plugin. diff --git a/docs/extend/legacy_plugins.md b/docs/extend/legacy_plugins.md new file mode 100644 index 0000000000..aa4fa4a9b3 --- /dev/null +++ b/docs/extend/legacy_plugins.md @@ -0,0 +1,93 @@ + + +# Use Docker Engine plugins + +This document describes the Docker Engine plugins generally available in Docker +Engine.

To view information on +plugins managed by Docker Engine currently in experimental status, refer to +[Docker Engine plugin system](index.md). + +This page is intended for people who want to develop their own Docker plugin. +If you just want to learn about or use Docker plugins, look +[here](legacy_plugins.md). + +## What plugins are + +A plugin is a process running on the same or a different host as the docker daemon, +which registers itself by placing a file on the same docker host in one of the plugin +directories described in [Plugin discovery](#plugin-discovery). + +Plugins have human-readable names, which are short, lowercase strings. For +example, `flocker` or `weave`. + +Plugins can run inside or outside containers. Currently running them outside +containers is recommended. + +## Plugin discovery + +Docker discovers plugins by looking for them in the plugin directory whenever a +user or container tries to use one by name. + +There are three types of files which can be put in the plugin directory. + +* `.sock` files are UNIX domain sockets. +* `.spec` files are text files containing a URL, such as `unix:///other.sock` or `tcp://localhost:8080`. +* `.json` files are text files containing a full json specification for the plugin. + +Plugins with UNIX domain socket files must run on the same docker host, whereas +plugins with spec or json files can run on a different host if a remote URL is specified. + +UNIX domain socket files must be located under `/run/docker/plugins`, whereas +spec files can be located either under `/etc/docker/plugins` or `/usr/lib/docker/plugins`. + +The name of the file (excluding the extension) determines the plugin name. + +For example, the `flocker` plugin might create a UNIX socket at +`/run/docker/plugins/flocker.sock`. + +You can define each plugin into a separated subdirectory if you want to isolate definitions from each other. +For example, you can create the `flocker` socket under `/run/docker/plugins/flocker/flocker.sock` and only +mount `/run/docker/plugins/flocker` inside the `flocker` container. + +Docker always searches for unix sockets in `/run/docker/plugins` first. It checks for spec or json files under +`/etc/docker/plugins` and `/usr/lib/docker/plugins` if the socket doesn't exist. The directory scan stops as +soon as it finds the first plugin definition with the given name. + +### JSON specification + +This is the JSON format for a plugin: + +```json +{ + "Name": "plugin-example", + "Addr": "https://example.com/docker/plugin", + "TLSConfig": { + "InsecureSkipVerify": false, + "CAFile": "/usr/shared/docker/certs/example-ca.pem", + "CertFile": "/usr/shared/docker/certs/example-cert.pem", + "KeyFile": "/usr/shared/docker/certs/example-key.pem", + } +} +``` + +The `TLSConfig` field is optional and TLS will only be verified if this configuration is present. + +## Plugin lifecycle + +Plugins should be started before Docker, and stopped after Docker. For +example, when packaging a plugin for a platform which supports `systemd`, you +might use [`systemd` dependencies]( +http://www.freedesktop.org/software/systemd/man/systemd.unit.html#Before=) to +manage startup and shutdown order. + +When upgrading a plugin, you should first stop the Docker daemon, upgrade the +plugin, then start Docker again. + +## Plugin activation + +When a plugin is first referred to -- either by a user referring to it by name +(e.g. `docker run --volume-driver=foo`) or a container already configured to +use a plugin being started -- Docker looks for the named plugin in the plugin +directory and activates it with a handshake. See Handshake API below. + +Plugins are *not* activated automatically at Docker daemon startup. Rather, +they are activated only lazily, or on-demand, when they are needed. + +## Systemd socket activation + +Plugins may also be socket activated by `systemd`. The official [Plugins helpers](https://github.com/docker/go-plugins-helpers) +natively supports socket activation. In order for a plugin to be socket activated it needs +a `service` file and a `socket` file. + +The `service` file (for example `/lib/systemd/system/your-plugin.service`): + +``` +[Unit] +Description=Your plugin +Before=docker.service +After=network.target your-plugin.socket +Requires=your-plugin.socket docker.service + +[Service] +ExecStart=/usr/lib/docker/your-plugin + +[Install] +WantedBy=multi-user.target +``` +The `socket` file (for example `/lib/systemd/system/your-plugin.socket`): +``` +[Unit] +Description=Your plugin + +[Socket] +ListenStream=/run/docker/plugins/your-plugin.sock + +[Install] +WantedBy=sockets.target +``` + +This will allow plugins to be actually started when the Docker daemon connects to +the sockets they're listening on (for instance the first time the daemon uses them +or if one of the plugin goes down accidentally). + +## API design + +The Plugin API is RPC-style JSON over HTTP, much like webhooks. + +Requests flow *from* the Docker daemon *to* the plugin. So the plugin needs to +implement an HTTP server and bind this to the UNIX socket mentioned in the +"plugin discovery" section. + +All requests are HTTP `POST` requests. + +The API is versioned via an Accept header, which currently is always set to +`application/vnd.docker.plugins.v1+json`. + +## Handshake API + +Plugins are activated via the following "handshake" API call. + +### /Plugin.Activate + +**Request:** empty body + +**Response:** +``` +{ + "Implements": ["VolumeDriver"] +} +``` + +Responds with a list of Docker subsystems which this plugin implements. +After activation, the plugin will then be sent events from this subsystem. + +Possible values are: + +* [`authz`](plugins_authorization.md) +* [`NetworkDriver`](plugins_network.md) +* [`VolumeDriver`](plugins_volume.md) + + +## Plugin retries + +Attempts to call a method on a plugin are retried with an exponential backoff +for up to 30 seconds.

To view information on plugins managed by Docker Engine currently in +experimental status, refer to [Docker Engine plugin system](index.md). + +Docker's out-of-the-box authorization model is all or nothing. Any user with +permission to access the Docker daemon can run any Docker client command. The +same is true for callers using Docker's remote API to contact the daemon. If you +require greater access control, you can create authorization plugins and add +them to your Docker daemon configuration. Using an authorization plugin, a +Docker administrator can configure granular access policies for managing access +to Docker daemon. + +Anyone with the appropriate skills can develop an authorization plugin. These +skills, at their most basic, are knowledge of Docker, understanding of REST, and +sound programming knowledge. This document describes the architecture, state, +and methods information available to an authorization plugin developer. + +## Basic principles + +Docker's [plugin infrastructure](plugin_api.md) enables +extending Docker by loading, removing and communicating with +third-party components using a generic API. The access authorization subsystem +was built using this mechanism. + +Using this subsystem, you don't need to rebuild the Docker daemon to add an +authorization plugin. You can add a plugin to an installed Docker daemon. You do +need to restart the Docker daemon to add a new plugin. + +An authorization plugin approves or denies requests to the Docker daemon based +on both the current authentication context and the command context. The +authentication context contains all user details and the authentication method. +The command context contains all the relevant request data. + +Authorization plugins must follow the rules described in [Docker Plugin API](plugin_api.md). +Each plugin must reside within directories described under the +[Plugin discovery](plugin_api.md#plugin-discovery) section. + +**Note**: the abbreviations `AuthZ` and `AuthN` mean authorization and authentication +respectively. + +## Default user authorization mechanism + +If TLS is enabled in the [Docker daemon](../security/https.md), the default user authorization flow extracts the user details from the certificate subject name. +That is, the `User` field is set to the client certificate subject common name, and the `AuthenticationMethod` field is set to `TLS`. + +## Basic architecture + +You are responsible for registering your plugin as part of the Docker daemon +startup. You can install multiple plugins and chain them together. This chain +can be ordered. Each request to the daemon passes in order through the chain. +Only when all the plugins grant access to the resource, is the access granted. + +When an HTTP request is made to the Docker daemon through the CLI or via the +remote API, the authentication subsystem passes the request to the installed +authentication plugin(s). The request contains the user (caller) and command +context. The plugin is responsible for deciding whether to allow or deny the +request. + +The sequence diagrams below depict an allow and deny authorization flow: + +![Authorization Allow flow](images/authz_allow.png) + +![Authorization Deny flow](images/authz_deny.png) + +Each request sent to the plugin includes the authenticated user, the HTTP +headers, and the request/response body. Only the user name and the +authentication method used are passed to the plugin. Most importantly, no user +credentials or tokens are passed. Finally, not all request/response bodies +are sent to the authorization plugin. Only those request/response bodies where +the `Content-Type` is either `text/*` or `application/json` are sent. + +For commands that can potentially hijack the HTTP connection (`HTTP +Upgrade`), such as `exec`, the authorization plugin is only called for the +initial HTTP requests. Once the plugin approves the command, authorization is +not applied to the rest of the flow. Specifically, the streaming data is not +passed to the authorization plugins. For commands that return chunked HTTP +response, such as `logs` and `events`, only the HTTP request is sent to the +authorization plugins. + +During request/response processing, some authorization flows might +need to do additional queries to the Docker daemon. To complete such flows, +plugins can call the daemon API similar to a regular user. To enable these +additional queries, the plugin must provide the means for an administrator to +configure proper authentication and security policies. + +## Docker client flows + +To enable and configure the authorization plugin, the plugin developer must +support the Docker client interactions detailed in this section. + +### Setting up Docker daemon + +Enable the authorization plugin with a dedicated command line flag in the +`--authorization-plugin=PLUGIN_ID` format. The flag supplies a `PLUGIN_ID` +value. This value can be the plugin’s socket or a path to a specification file. +Authorization plugins can be loaded without restarting the daemon. Refer +to the [`dockerd` documentation](../reference/commandline/dockerd.md#configuration-reloading) for more information. + +```bash +$ dockerd --authorization-plugin=plugin1 --authorization-plugin=plugin2,... +``` + +Docker's authorization subsystem supports multiple `--authorization-plugin` parameters. + +### Calling authorized command (allow) + +```bash +$ docker pull centos +... +f1b10cd84249: Pull complete +... +``` + +### Calling unauthorized command (deny) + +```bash +$ docker pull centos +... +docker: Error response from daemon: authorization denied by plugin PLUGIN_NAME: volumes are not allowed. +``` + +### Error from plugins + +```bash +$ docker pull centos +... +docker: Error response from daemon: plugin PLUGIN_NAME failed with error: AuthZPlugin.AuthZReq: Cannot connect to the Docker daemon.

This adds an --update-max-failure-ratio flag that controls how many tasks need to fail to update for the update as a whole to be considered a failure. A counterpart flag, --update-monitor, controls how long to monitor each task for a failure after starting it during the update. - Rollback flag: service update --rollback reverts the service to its previous version. If a service update encounters task failures, or fails to function properly for some other reason, the user can roll back the update. SwarmKit also has the ability to roll back updates automatically after hitting the failure thresholds, but we've decided not to expose this in the Docker API/CLI for now, favoring a workflow where the decision to roll back is always made by an admin. Depending on user feedback, we may add a "rollback" option to --update-failure-action in the future.

The default value is 15s. The `--shutdown-timeout` parameter is added to daemon options and config file. It will also be updated during daemon reload. Additional test cases have been added to cover the change. This fix fixes #22471.

The subsequent use of indexes will then affect the string. This leads to `docker rmi ` to complete on the header line instead of nothing. Therefore, for each use of `(f)`, we ensure that we have an extra new line to be sure we get an array. Credit to @povesteam for the original report and fix in #27373.

This fix updates the help output for consistency. This fix also updates the related docs in `service_update.md`. The help output in `service_update.md` has been quite out-of-sync with the actual output so this fix replaces the output with the most up-to-date output. This fix is related to #27567.

I'm adding them here to fix this oversight. --max-snapshots may be useful for debugging purposes and more conservative users who want to store rolling backups of old versions of the Raft state. --snapshot-interval is most useful for performance tuning. The default value of 10000 may not be ideal for some setups. There is also a LogEntriesForSlowFollowers option that is not exposed.

From ac4b6e35056b8a99993919411421e5a5fb2f30e9 Mon Sep 17 00:00:00 2001 From: Yong Tang Date: Tue, 8 Nov 2016 07:06:07 -0800 Subject: [PATCH 2013/2538] Remove `-ptr` from the help output of `service create` This fix is based on the comment: https://github.com/docker/docker/pull/28147#discussion_r86996347 Previously the output string of the `DurationOpt` is `duration-ptr` and `Uint64Opt` is `uint64-ptr`. While it is clear to developers, for a normal user `-ptr` might not be very informative. On the other hand, the default value of `DurationOpt` and `Uint64Opt` has already been quite informative: `none`. That means if no flag provided, the value will be treated as none. (like a ptr with nil as the default) For that reason this fix removes the `-ptr`. Also, the output in the docs of `service create` has been quite out-of-sync with the true output. So this fix updates the docs to have the most up-to-date help output of `service create --help`. This fix is related to #28147.

User might incorrectly assume the number of replicas would be `0` (`none`) by default, while the actual default is `1`. The issue comes from the fact that some of the default values are from daemon and it is not possible for client to find out the default value. In this case, it might be better to just simply not displaying `(default none)`. This fix returns "" for `Uint64Opt` so that `(default none)` is hidden. In addition to `--replicas`, this fix also changes `--restart-delay`, `--restart-max-attempts`, `--stop-grace-period`, `--health-interval`, `--health-timeout`, and `--restart-window` in a similiar fashion. New Output: ``` --health-interval duration Time between running the check (ns|us|ms|s|m|h) --health-timeout duration Maximum time to allow one check to run (ns|us|ms|s|m|h) ... --replicas uint Number of tasks ... --restart-delay duration Delay between restart attempts (ns|us|ms|s|m|h) --restart-max-attempts uint Maximum number of restarts before giving up --restart-window duration Window used to evaluate the restart policy (ns|us|ms|s|m|h) ... --stop-grace-period duration Time to wait before force killing a container (ns|us|ms|s|m|h) ``` The docs has been updated. Note the docs for help output of `service create/update` is out of sync with the current master. This fix replace with the update-to-date help output. This fix fixes 29291.

The output of `docker stack ps` reused the same output as `docker service/node ps`. However, the `-a` was still there. It might make sense to remove `docker stack ps -a` as well to bring consistency with `docker service/node ps`. This fix is related to #28507, #28885, and #25983.

If you specify, ` -v /HOST-DIR:/CONTAINER-DIR`, Docker - bind mounts `/HOST-DIR` in the host to `/CONTAINER-DIR` in the Docker - container. If 'HOST-DIR' is omitted, Docker automatically creates the new - volume on the host. The `OPTIONS` are a comma delimited list and can be: - - * [rw|ro] - * [z|Z] - * [`[r]shared`|`[r]slave`|`[r]private`] - -The `CONTAINER-DIR` must be an absolute path such as `/src/docs`. The `HOST-DIR` -can be an absolute path or a `name` value. A `name` value must start with an -alphanumeric character, followed by `a-z0-9`, `_` (underscore), `.` (period) or -`-` (hyphen). An absolute path starts with a `/` (forward slash). - -If you supply a `HOST-DIR` that is an absolute path, Docker bind-mounts to the -path you specify. If you supply a `name`, Docker creates a named volume by that -`name`. For example, you can specify either `/foo` or `foo` for a `HOST-DIR` -value. If you supply the `/foo` value, Docker creates a bind-mount. If you -supply the `foo` specification, Docker creates a named volume. - -You can specify multiple **-v** options to mount one or more mounts to a -container. To use these same mounts in other containers, specify the -**--volumes-from** option also. - -You can add `:ro` or `:rw` suffix to a volume to mount it read-only or -read-write mode, respectively. By default, the volumes are mounted read-write. -See examples. - -Labeling systems like SELinux require that proper labels are placed on volume -content mounted into a container. Without a label, the security system might -prevent the processes running inside the container from using the content. By -default, Docker does not change the labels set by the OS. - -To change a label in the container context, you can add either of two suffixes -`:z` or `:Z` to the volume mount. These suffixes tell Docker to relabel file -objects on the shared volumes. The `z` option tells Docker that two containers -share the volume content. As a result, Docker labels the content with a shared -content label. Shared volume labels allow all containers to read/write content. -The `Z` option tells Docker to label the content with a private unshared label. -Only the current container can use a private volume. - -By default bind mounted volumes are `private`. That means any mounts done -inside container will not be visible on host and vice-a-versa. One can change -this behavior by specifying a volume mount propagation property. Making a -volume `shared` mounts done under that volume inside container will be -visible on host and vice-a-versa. Making a volume `slave` enables only one -way mount propagation and that is mounts done on host under that volume -will be visible inside container but not the other way around. - -To control mount propagation property of volume one can use `:[r]shared`, -`:[r]slave` or `:[r]private` propagation flag. Propagation property can -be specified only for bind mounted volumes and not for internal volumes or -named volumes. For mount propagation to work source mount point (mount point -where source dir is mounted on) has to have right propagation properties. For -shared volumes, source mount point has to be shared. And for slave volumes, -source mount has to be either shared or slave. - -Use `df ` to figure out the source mount and then use -`findmnt -o TARGET,PROPAGATION ` to figure out propagation -properties of source mount. If `findmnt` utility is not available, then one -can look at mount entry for source mount point in `/proc/self/mountinfo`. Look -at `optional fields` and see if any propagaion properties are specified. -`shared:X` means mount is `shared`, `master:X` means mount is `slave` and if -nothing is there that means mount is `private`. - -To change propagation properties of a mount point use `mount` command. For -example, if one wants to bind mount source directory `/foo` one can do -`mount --bind /foo /foo` and `mount --make-private --make-shared /foo`. This -will convert /foo into a `shared` mount point. Alternatively one can directly -change propagation properties of source mount. Say `/` is source mount for -`/foo`, then use `mount --make-shared /` to convert `/` into a `shared` mount. - -> **Note**: -> When using systemd to manage the Docker daemon's start and stop, in the systemd -> unit file there is an option to control mount propagation for the Docker daemon -> itself, called `MountFlags`. The value of this setting may cause Docker to not -> see mount propagation changes made on the mount point. For example, if this value -> is `slave`, you may not be able to use the `shared` or `rshared` propagation on -> a volume. - - -To disable automatic copying of data from the container path to the volume, use -the `nocopy` flag. The `nocopy` flag can be set on bind mounts and named volumes. - -**--volume-driver**="" - Container's volume driver. This driver creates volumes specified either from - a Dockerfile's `VOLUME` instruction or from the `docker run -v` flag. - See **docker-volume-create(1)** for full details. - -**--volumes-from**=[] - Mount volumes from the specified container(s) - -**-w**, **--workdir**="" - Working directory inside the container - -# EXAMPLES - -## Specify isolation technology for container (--isolation) - -This option is useful in situations where you are running Docker containers on -Windows. The `--isolation=` option sets a container's isolation -technology. On Linux, the only supported is the `default` option which uses -Linux namespaces. On Microsoft Windows, you can specify these values: - -* `default`: Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value. -* `process`: Namespace isolation only. -* `hyperv`: Hyper-V hypervisor partition-based isolation. - -Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`. - -# HISTORY -August 2014, updated by Sven Dowideit -September 2014, updated by Sven Dowideit -November 2014, updated by Sven Dowideit diff --git a/man/docker-exec.1.md b/man/docker-exec.1.md deleted file mode 100644 index fe9c279e7e..0000000000 --- a/man/docker-exec.1.md +++ /dev/null @@ -1,71 +0,0 @@ -% DOCKER(1) Docker User Manuals -% Docker Community -% JUNE 2014 -# NAME -docker-exec - Run a command in a running container - -# SYNOPSIS -**docker exec** -[**-d**|**--detach**] -[**--detach-keys**[=*[]*]] -[**-e**|**--env**[=*[]*]] -[**--help**] -[**-i**|**--interactive**] -[**--privileged**] -[**-t**|**--tty**] -[**-u**|**--user**[=*USER*]] -CONTAINER COMMAND [ARG...] - -# DESCRIPTION - -Run a process in a running container. - -The command started using `docker exec` will only run while the container's primary -process (`PID 1`) is running, and will not be restarted if the container is restarted. - -If the container is paused, then the `docker exec` command will wait until the -container is unpaused, and then run - -# OPTIONS -**-d**, **--detach**=*true*|*false* - Detached mode: run command in the background.

Add `pluginsFormat` for config.json. Related docs has been updated. Several unit tests have been added to cover the changes. This fix is related to 28708 and 28735.

Depending on the `verify` boolean, the message is "Skip image verification", or "Skip image signing". "Signing" is intended for `docker push` / `docker plugin push`. During the migration to Cobra, this boolean got flipped for `docker push` (9640e3a4514f96a890310757a09fd77a3c70e931), causing `docker push` to show the incorrect flag description. This patch changes the flags to use the correct description for `docker push`, and `docker plugin push`. To prevent this confusion in future, the boolean argument is removed, and a `AddTrustSigningFlags()` function is added.

We are able to find the timestamp through `docker network inspect` though. However, as we allows networks to be pruned based on the timestamp (see 29226), showing the timestamp in `docker network ls --format` would be much useful now.

Since plugin resources (e.g. volumes) are tied to a plugin ID, this is important to ensure resources aren't lost. The plugin must be disabled while upgrading (errors out if enabled). This does not add any convenience flags for automatically disabling/re-enabling the plugin during before/after upgrade.

One example of where this can be useful is to balance tasks over a set +of datacenters or availability zones. The example below illustrates this: + +```bash +$ docker service create \ + --replicas 9 \ + --name redis_2 \ + --placement-pref 'spread=node.labels.datacenter' \ + redis:3.0.6 +``` + +This uses `--placement-pref` with a `spread` strategy (currently the only +supported strategy) to spread tasks evenly over the values of the `datacenter` +node label. In this example, we assume that every node has a `datacenter` node +label attached to it. If there are three different values of this label among +nodes in the swarm, one third of the tasks will be placed on the nodes +associated with each value. This is true even if there are more nodes with one +value than another. For example, consider the following set of nodes: + +- Three nodes with `node.labels.datacenter=east` +- Two nodes with `node.labels.datacenter=south` +- One node with `node.labels.datacenter=west` + +Since we are spreading over the values of the `datacenter` label and the +service has 9 replicas, 3 replicas will end up in each datacenter. There are +three nodes associated with the value `east`, so each one will get one of the +three replicas reserved for this value. There are two nodes with the value +`south`, and the three replicas for this value will be divided between them, +with one receiving two replicas and another receiving just one. Finally, `west` +has a single node that will get all three replicas reserved for `west`. + +If the nodes in one category (for example, those with +`node.labels.datacenter=south`) can't handle their fair share of tasks due to +constraints or resource limitations, the extra tasks will be assigned to other +nodes instead, if possible. + +Both engine labels and node labels are supported by placement preferences. The +example above uses a node label, because the label is referenced with +`node.labels.datacenter`. To spread over the values of an engine label, use +`--placement-pref spread=engine.labels.`. + +It is possible to add multiple placement preferences to a service. This +establishes a hierarchy of preferences, so that tasks are first divided over +one category, and then further divided over additional categories. One example +of where this may be useful is dividing tasks fairly between datacenters, and +then splitting the tasks within each datacenter over a choice of racks. To add +multiple placement preferences, specify the `--placement-pref` flag multiple +times.

As `docker service ls` has a `MODE` column by default, it is natural to support `--filter mode=global|replicated` for `docker service ls`. There are multiple ways to address the issue. One way is to pass the filter of mode to SwarmKit, another way is to process the filter of mode in the daemon. This fix process the filter in the daemon. Related docs has been updated. An integration test has been added. This fix fixes 31325.

2426/2538] Add `--filter scope=swarm|local` for `docker network ls` This fix tries to address the request in 31324 by adding `--filter scope=swarm|local` for `docker network ls`. As `docker network ls` has a `SCOPE` column by default, it is natural to add the support of `--filter scope=swarm|local`. This fix adds the `scope=swarm|local` support for `docker network ls --filter`. Related docs has been updated. Additional unit test cases have been added. This fix fixes 31324.

Logging plugins are not currently supported on Windows. + +**Request**: +```json +{ + "File": "/path/to/file/stream", + "Info": { + "ContainerID": "123456" + } +} +``` + +`File` is the path to the log stream that needs to be consumed. Each call to +`StartLogging` should provide a different file path, even if it's a container +that the plugin has already received logs for prior. The file is created by +docker with a randomly generated name. + +`Info` is details about the container that's being logged. This is fairly +free-form, but is defined by the following struct definition: + +```go +type Info struct { + Config map[string]string + ContainerID string + ContainerName string + ContainerEntrypoint string + ContainerArgs []string + ContainerImageID string + ContainerImageName string + ContainerCreated time.Time + ContainerEnv []string + ContainerLabels map[string]string + LogPath string + DaemonName string +} +``` + + +`ContainerID` will always be supplied with this struct, but other fields may be +empty or missing. + +**Response** +```json +{ + "Err": "" +} +``` + +If an error occurred during this request, add an error message to the `Err` field +in the response. If no error then you can either send an empty response (`{}`) +or an empty value for the `Err` field. + +The driver should at this point be consuming log messages from the passed in file. +If messages are unconsumed, it may cause the contaier to block while trying to +write to its stdio streams. + +Log stream messages are encoded as protocol buffers. The protobuf definitions are +in the +[docker repository](https://github.com/docker/docker/blob/master/api/types/plugins/logdriver/entry.proto). + +Since protocol buffers are not self-delimited you must decode them from the stream +using the following stream format: + +``` +[size][message] +``` + +Where `size` is a 4-byte big endian binary encoded uint32. `size` in this case +defines the size of the next message. `message` is the actual log entry. + +A reference golang implementation of a stream encoder/decoder can be found +[here](https://github.com/docker/docker/blob/master/api/types/plugins/logdriver/io.go) + +### `/LogDriver.StopLogging` + +Signals to the plugin to stop collecting logs from the defined file. +Once a response is received, the file will be removed by Docker.

Adds several new options to the devmapper storage-opts: - dm.directlvm_device="" - path to the block device to configure for direct-lvm - dm.thinp_percent=95 - sets the percentage of space to use for storage from the passed in block device - dm.thinp_metapercent=1 - sets the percentage of space to for metadata storage from the passed in block device - dm.thinp_autoextend_threshold=80 - sets the threshold for when `lvm` should automatically extend the thin pool as a percentage of the total storage space - dm.thinp_autoextend_percent=20 - sets the percentage to increase the thin pool by when an autoextend is triggered. Defaults are taken from [here](https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/configure-direct-lvm-mode-for-production) The only option that is required is `dm.directlvm_device` for docker to set everything up.

In silent mode (with `-q`) there is no change, on success the only output will be the resulting image digest as it was previosuly. There was no wrapper to just output an Aux section without enclosing it in a Progress, so add one here. Added some tests to integration cli tests.

For the existing tests the scripts will use a frozen version of the docker cli with a DOCKER_API_VERSION frozen to 1.30, which should ensure that the CI remains green at all times. To help contributors develop and test manually with a modified docker cli, this commit also adds a DOCKER_CLI_PATH environment variable to the Makefile. This allows to set the path of a custom cli that will be available inside the development container and used to run the integration tests.

This is useful because metrics are not neccessarily at a standard location... `--metrics-addr` must be set, and must currently be a TCP socket. Even if metrics are done via a unix socket, there's no guarentee where the socket may be located on the system, making bind-mounting such a socket into a container difficult (and racey, failure-prone on daemon restart). Metrics plugins side-step this issue by always listening on a unix socket and then bind-mounting that into a known path in the plugin container. Note there has been similar work in the past (and ultimately punted at the time) for consistent access to the Docker API from within a container. Why not add metrics to the Docker API and just provide a plugin with access to the Docker API? Certainly this can be useful, but gives a lot of control/access to a plugin that may only need the metrics. We can look at supporting API plugins separately for this reason.

This patch also adds some more CLI integration tests for waiting for a created container and waiting with the new --until-removed flag.

This patch bumps the version checks to use 1.30 instead. This patch also makes a minor update to a testfile which was added to the builder/dockerfile package.

It +is paranoid about its input (so you can safely feed it user-supplied +data), it is fast, it supports common extensions (tables, smart +punctuation substitutions, etc.), and it is safe for all utf-8 +(unicode) input. + +HTML output is currently supported, along with Smartypants +extensions. An experimental LaTeX output engine is also included. + +It started as a translation from C of [Sundown][3]. + + +Installation +------------ + +Blackfriday is compatible with Go 1. If you are using an older +release of Go, consider using v1.1 of blackfriday, which was based +on the last stable release of Go prior to Go 1. You can find it as a +tagged commit on github. + +With Go 1 and git installed: + + go get github.com/russross/blackfriday + +will download, compile, and install the package into your `$GOPATH` +directory hierarchy. Alternatively, you can achieve the same if you +import it into a project: + + import "github.com/russross/blackfriday" + +and `go get` without parameters. + +Usage +----- + +For basic usage, it is as simple as getting your input into a byte +slice and calling: + + output := blackfriday.MarkdownBasic(input) + +This renders it with no extensions enabled. To get a more useful +feature set, use this instead: + + output := blackfriday.MarkdownCommon(input) + +### Sanitize untrusted content + +Blackfriday itself does nothing to protect against malicious content. If you are +dealing with user-supplied markdown, we recommend running blackfriday's output +through HTML sanitizer such as +[Bluemonday](https://github.com/microcosm-cc/bluemonday). + +Here's an example of simple usage of blackfriday together with bluemonday: + +``` go +import ( + "github.com/microcosm-cc/bluemonday" + "github.com/russross/blackfriday" +) + +// ... +unsafe := blackfriday.MarkdownCommon(input) +html := bluemonday.UGCPolicy().SanitizeBytes(unsafe) +``` + +### Custom options + +If you want to customize the set of options, first get a renderer +(currently either the HTML or LaTeX output engines), then use it to +call the more general `Markdown` function. For examples, see the +implementations of `MarkdownBasic` and `MarkdownCommon` in +`markdown.go`. + +You can also check out `blackfriday-tool` for a more complete example +of how to use it. Download and install it using: + + go get github.com/russross/blackfriday-tool + +This is a simple command-line tool that allows you to process a +markdown file using a standalone program. You can also browse the +source directly on github if you are just looking for some example +code: + +* + +Note that if you have not already done so, installing +`blackfriday-tool` will be sufficient to download and install +blackfriday in addition to the tool itself. The tool binary will be +installed in `$GOPATH/bin`. This is a statically-linked binary that +can be copied to wherever you need it without worrying about +dependencies and library versions. + + +Features +-------- + +All features of Sundown are supported, including: + +* **Compatibility**. The Markdown v1.0.3 test suite passes with + the `--tidy` option. Without `--tidy`, the differences are + mostly in whitespace and entity escaping, where blackfriday is + more consistent and cleaner. + +* **Common extensions**, including table support, fenced code + blocks, autolinks, strikethroughs, non-strict emphasis, etc. + +* **Safety**. Blackfriday is paranoid when parsing, making it safe + to feed untrusted user input without fear of bad things + happening. The test suite stress tests this and there are no + known inputs that make it crash. If you find one, please let me + know and send me the input that does it. + + NOTE: "safety" in this context means *runtime safety only*. In order to + protect yourself against JavaScript injection in untrusted content, see + [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content). + +* **Fast processing**. It is fast enough to render on-demand in + most web applications without having to cache the output. + +* **Thread safety**. You can run multiple parsers in different + goroutines without ill effect. There is no dependence on global + shared state. + +* **Minimal dependencies**. Blackfriday only depends on standard + library packages in Go. The source code is pretty + self-contained, so it is easy to add to any project, including + Google App Engine projects. + +* **Standards compliant**. Output successfully validates using the + W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional. + + +Extensions +---------- + +In addition to the standard markdown syntax, this package +implements the following extensions: + +* **Intra-word emphasis supression**. The `_` character is + commonly used inside words when discussing code, so having + markdown interpret it as an emphasis command is usually the + wrong thing. Blackfriday lets you treat all emphasis markers as + normal characters when they occur inside a word. + +* **Tables**. Tables can be created by drawing them in the input + using a simple syntax: + + ``` + Name | Age + --------|------ + Bob | 27 + Alice | 23 + ``` + +* **Fenced code blocks**. In addition to the normal 4-space + indentation to mark code blocks, you can explicitly mark them + and supply a language (to make syntax highlighting simple). Just + mark it like this: + + ``` go + func getTrue() bool { + return true + } + ``` + + You can use 3 or more backticks to mark the beginning of the + block, and the same number to mark the end of the block. + +* **Definition lists**. A simple definition list is made of a single-line + term followed by a colon and the definition for that term. + + Cat + : Fluffy animal everyone likes + + Internet + : Vector of transmission for pictures of cats + + Terms must be separated from the previous definition by a blank line. + +* **Footnotes**. A marker in the text that will become a superscript number; + a footnote definition that will be placed in a list of footnotes at the + end of the document. A footnote looks like this: + + This is a footnote.[^1] + + [^1]: the footnote text. + +* **Autolinking**. Blackfriday can find URLs that have not been + explicitly marked as links and turn them into links. + +* **Strikethrough**. Use two tildes (`~~`) to mark text that + should be crossed out. + +* **Hard line breaks**. With this extension enabled (it is off by + default in the `MarkdownBasic` and `MarkdownCommon` convenience + functions), newlines in the input translate into line breaks in + the output. + +* **Smart quotes**. Smartypants-style punctuation substitution is + supported, turning normal double- and single-quote marks into + curly quotes, etc. + +* **LaTeX-style dash parsing** is an additional option, where `--` + is translated into `–`, and `---` is translated into + `—`. This differs from most smartypants processors, which + turn a single hyphen into an ndash and a double hyphen into an + mdash. + +* **Smart fractions**, where anything that looks like a fraction + is translated into suitable HTML (instead of just a few special + cases like most smartypant processors). For example, `4/5` + becomes `4⁄5`, which renders as + 4⁄5. + + +Other renderers +--------------- + +Blackfriday is structured to allow alternative rendering engines. Here +are a few of note: + +* [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown): + provides a GitHub Flavored Markdown renderer with fenced code block + highlighting, clickable header anchor links. + + It's not customizable, and its goal is to produce HTML output + equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode), + except the rendering is performed locally. + +* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt, + but for markdown. + +* LaTeX output: renders output as LaTeX. This is currently part of the + main Blackfriday repository, but may be split into its own project + in the future. If you are interested in owning and maintaining the + LaTeX output component, please be in touch. + + It renders some basic documents, but is only experimental at this + point. In particular, it does not do any inline escaping, so input + that happens to look like LaTeX code will be passed through without + modification. + +* [Md2Vim](https://github.com/FooSoft/md2vim): transforms markdown files into vimdoc format. + + +Todo +---- + +* More unit testing +* Improve unicode support. It does not understand all unicode + rules (about what constitutes a letter, a punctuation symbol, + etc.), so it may fail to detect word boundaries correctly in + some instances. It is safe on all utf-8 input. + + +License +------- + +[Blackfriday is distributed under the Simplified BSD License](LICENSE.txt) + + + [1]: http://daringfireball.net/projects/markdown/ "Markdown" + [2]: http://golang.org/ "Go Language" + [3]: https://github.com/vmg/sundown "Sundown" diff --git a/vendor/github.com/russross/blackfriday/block.go b/vendor/github.com/russross/blackfriday/block.go new file mode 100644 index 0000000000..3f4af787e3 --- /dev/null +++ b/vendor/github.com/russross/blackfriday/block.go @@ -0,0 +1,1420 @@ +// +// Blackfriday Markdown Processor +// Available at http://github.com/russross/blackfriday +// +// Copyright © 2011 Russ Ross . +// Distributed under the Simplified BSD License. +// See README.md for details. +// + +// +// Functions to parse block-level elements. +// + +package blackfriday + +import ( + "bytes" + + "github.com/shurcooL/sanitized_anchor_name" +) + +// Parse block-level data. +// Note: this function and many that it calls assume that +// the input buffer ends with a newline. +func (p *parser) block(out *bytes.Buffer, data []byte) { + if len(data) == 0 || data[len(data)-1] != '\n' { + panic("block input is missing terminating newline") + } + + // this is called recursively: enforce a maximum depth + if p.nesting >= p.maxNesting { + return + } + p.nesting++ + + // parse out one block-level construct at a time + for len(data) > 0 { + // prefixed header: + // + // # Header 1 + // ## Header 2 + // ... + // ###### Header 6 + if p.isPrefixHeader(data) { + data = data[p.prefixHeader(out, data):] + continue + } + + // block of preformatted HTML: + // + //
