`strings.Trim()` strips any character listed in the `cutset` argument,

Commit 330a0035334871d92207b583c1c36d52a244753f added a `--detach=false` option
to various service-related commands, with the intent to make this the default in
a future version (17.09).
This patch changes the default to use "interactive" (non-detached), allowing
users to override this by setting the `--detach` option.
To prevent problems when connecting to older daemon versions (17.05 and below,
see commit db60f25561), the detach option is
ignored for those versions, and detach is always true.
Before this change, a warning was printed to announce the upcoming default:
$ docker service create nginx:alpine
saxiyn3pe559d753730zr0xer
Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
After this change, no warning is printed, but `--detach` is disabled;
$ docker service create nginx:alpine
y9jujwzozi0hwgj5yaadzliq6
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]
verify: Service converged
Setting the `--detach` flag makes the cli use the pre-17.06 behavior:
$ docker service create --detach nginx:alpine
280hjnzy0wzje5o56gr22a46n
Running against a 17.03 daemon, without specifying the `--detach` flag;

The --allow-nondistributable-artifacts daemon option specifies
registries to which foreign layers should be pushed. (By default,
foreign layers are not pushed to registries.)
Additionally, to make this option effective, foreign layers are now
pulled from the registry if possible, falling back to the URLs in the
image manifest otherwise.
This option is useful when pushing images containing foreign layers to a
registry on an air-gapped network so hosts on that network can pull the
images without connecting to another server.

Allows for a plugin type that can be used to scrape metrics.
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.

Starting with this commit, integration tests should no longer rely on
the docker cli, they should be API tests instead. 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 synonymous with `docker run --cidfile=FILE` and writes the digest of
the newly built image to the named file. This is intended to be used by build
systems which want to avoid tagging (perhaps because they are in CI or
otherwise want to avoid fixed names which can clash) by enabling e.g. Makefile
constructs like:
image.id: Dockerfile
docker build --iidfile=image.id .
do-some-more-stuff: image.id
do-stuff-with <image.id
Currently the only way to achieve this is to use `docker build -q` and capture
the stdout, but at the expense of losing the build output.
In non-silent mode (without `-q`) with API >= v1.29 the caller will now see a
`JSONMessage` with the `Aux` field containing a `types.BuildResult` in the
output stream for each image/layer produced during the build, with the final
one being the end product. Having all of the intermediate images might be
interesting in some cases.
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.

Instead of forcing users to manually configure a block device to use
with devmapper, this gives the user the option to let the devmapper
driver configure a device for them.
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.
Changes to these settings are not currently supported and will error
out.
Future work could support allowing changes to these values.

Logging plugins use the same HTTP interface as other plugins for basic
command operations meanwhile actual logging operations are handled (on
Unix) via a fifo.
The plugin interface looks like so:
```go
type loggingPlugin interface {
StartLogging(fifoPath string, loggingContext Context) error
StopLogging(fifoPath)
```
This means a plugin must implement `LoggingDriver.StartLogging` and
`LoggingDriver.StopLogging` endpoints and be able to consume the passed
in fifo.
Logs are sent via stream encoder to the fifo encoded with protobuf.

This persists the "propagated mount" for plugins outside the main
rootfs. This enables `docker plugin upgrade` to not remove potentially
important data during upgrade rather than forcing plugin authors to hard
code a host path to persist data to.
Also migrates old plugins that have a propagated mount which is in the
rootfs on daemon startup.

This allows a plugin to be upgraded without requiring to
uninstall/reinstall a plugin.
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.
Since an upgrade may change requested permissions, the user is required
to accept permissions just like `docker plugin install`.

Working directory processing was handled differently for Hyper-V and Windows-Server containers, as annotated in the builder documentation (updated in this PR). For Hyper-V containers, the working directory set by WORKDIR was not created. This PR makes Hyper-V containers work the same as Windows Server containers (and the same as Linux).

Commit ed13c3abfb242905ec012e8255dc6f26dcf122f6 added flags
for Docker Content Trust. 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.

This fix tries to address the issue raised in 29291 where
the output of `--replicas` in `service create/update`:
```
--replicas uint Number of tasks (default none)
```
is misleading. 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)

Legacy plugins expect host-relative paths (such as for Volume.Mount).
However, a containerized plugin cannot respond with a host-relative
path. Therefore, this commit modifies new volume plugins' paths in Mount
and List to prepend the container's rootfs path.
This introduces a new PropagatedMount field in the Plugin Config.
When it is set for volume plugins, RootfsPropagation is set to rshared
and the path specified by PropagatedMount is bind-mounted with rshared
prior to launching the container. This is so that the daemon code can
access the paths returned by the plugin from the host mount namespace.

as long as there is no ambiguity.

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`.

Add the following options to "swarm init" and "swarm update":
- --max-snapshots: Retain this many old Raft snapshots in addition
to the latest one
- --snapshot-interval: Number of log entries between Raft snapshots
These options already existed in SwarmKit and the Docker API but were
never exposed in the CLI. 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. I
decided not to expose it along with these others because I don't think
it's generally useful (and I'm not sure what I would call the CLI flag).
But if people want, I can expose it for the sake of completeness.

This fix tries to address the proposal raised in 27921 and add
`--cpus` flag for `docker run/create`.
Basically, `--cpus` will allow user to specify a number (possibly partial)
about how many CPUs the container will use. For example, on a 2-CPU system
`--cpus 1.5` means the container will take 75% (1.5/2) of the CPU share.
This fix adds a `NanoCPUs` field to `HostConfig` since swarmkit alreay
have a concept of NanoCPUs for tasks. The `--cpus` flag will translate
the number into reused `NanoCPUs` to be consistent.

Currently, there's no way to restart the tasks of a service without
making an actual change to the service. This leads to us giving awkward
workarounds as in
https://github.com/docker/docker.github.io/pull/178/files, where we tell
people to scale a service up and down to restore balance, or make
unnecessary changes to trigger a restart.
This change adds a --force option to "docker service update", which
forces the service to be updated even if no changes require that.
Since rolling update parameters are respected, the user can use
"docker service --force" to do a rolling restart. For example, the
following is supported:
docker service update --force --update-parallelism 2 \
--update-delay 5s myservice
Since the default value of --update-parallelism is 1, the default
behavior is to restart the service one task at a time.

This adds support for two enhancements to swarm service rolling updates:
- Failure thresholds: In Docker 1.12, a service update could be set up
to either pause or continue after a single failure occurs. 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.

When xfs filesystem is being used on top of thin pool, xfs can get ENOSPC
errors from thin pool when thin pool is full. 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.

this change improves the instructions for
swarm join-token and swarm init;
- only print the join-token command for workers
instead of for both managers and workers, to
prevent users from copying the wrong command.
An extra line is added to explain how to obtain
the manager token.
- print a message that a token was rotated
sucesfully if '--rotate' is used.
- add some extra white-space before / after
the join commands, to make copy/pasting
easier.
this change also does some refactoring of join-token;
- move flagname-constants together with other constants
- use variables for selected role ("worker" / "manager")
to prevent checking for them multiple times, and to
keep the "worker" / "manager" sting centralized
- add an extra blank line after "join-token" instructions
this makes it easier to copy, and cleans up the
code a tiny bit

Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.
This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.
The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:
```
$ docker service ps condescending_cori

e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 13 minutes ago Running 6c6d232a5d0e

running:

This changes the default behavior so that rolling updates will not
proceed once an updated task fails to start, or stops running during the
update. 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. This is a minimal
solution for 1.12.

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.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. 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. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

Kernel memory is not allowed to be updated if container is
running, it's not actually a precise kernel limitation.
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.
So update kernel memory of a running container with kernel memory
initialized is allowed, we should soften the limitation by docker.

The current behavior of `docker swarm init` is to set up a swarm that
has no secret for joining, and does not require manual acceptance for
workers. 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`.

This PR adds support for user-defined health-check probes for Docker
containers. 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.

Currently the default seccomp profile is fixed. This changes it
so that it varies depending on the Linux capabilities selected with
the --cap-add and --cap-drop options. Without this, if a user adds
privileges, eg to allow ptrace with --cap-add sys_ptrace then still
cannot actually use ptrace as it is still blocked by seccomp, so
they will probably disable seccomp or use --privileged. With this
change the syscalls that are needed for the capability are also
allowed by the seccomp profile based on the selected capabilities.
While this patch makes it easier to do things with for example
cap_sys_admin enabled, as it will now allow creating new namespaces
and use of mount, it still allows less than --cap-add cap_sys_admin
--security-opt seccomp:unconfined would have previously. It is not
recommended that users run containers with cap_sys_admin as this does
give full access to the host machine.
It also cleans up some architecture specific system calls to be
only selected when needed.

This fix tries to address issues raised in #20936 and #22443
where `docker pull` or `docker push` fails because of the
concurrent connection failing.
Currently, the number of maximum concurrent connections is
controlled by `maxDownloadConcurrency` and `maxUploadConcurrency`
which are hardcoded to 3 and 5 respectively. Therefore, in
situations where network connections don't support multiple
downloads/uploads, failures may encounter for `docker push`
or `docker pull`.
This fix tries changes `maxDownloadConcurrency` and
`maxUploadConcurrency` to adjustable by passing
`--max-concurrent-uploads` and `--max-concurrent-downloads` to
`docker daemon` command.
The documentation related to docker daemon has been updated.
Additional test case have been added to cover the changes in this fix.
This fix fixes#20936. This fix fixes#22443.

Since 1.9, driver specific log tag options
`syslog-tag`
`gelf-tag`
`fluentd-tag`
have been deprecated in favor of the generic tag
option which is standard across different logging
drivers.
This fix removed the deprecated driver specific
log tag options of `syslog-tag`, `gelf-tag`,
`fluentd-tag` for 1.12 and updated the docs.

The jsonlog logger currently allows specifying envs and labels that
should be propagated to the log message, however there has been no way
to read that back.
This adds a new API option to enable inserting these attrs back to the
log reader.
With timestamps, this looks like so:
```
92016-04-08T15:28:09.835913720Z foo=bar,hello=world hello
```
The extra attrs are comma separated before the log message but after
timestamps.
Without timestaps it looks like so:
```
foo=bar,hello=world hello
```

This patch did following:
1) Make filter check logic same as `docker ps ` filters
Right now docker container logic work as following:
when same filter used like below:
-f name=jack -f name=tom
it would get all containers name is jack or tom(it is or logic)
when different filter used like below:
-f name=jack -f id=7d1
it would get all containers name is jack and id contains 7d1(it is and logic)
It would make sense in many user cases, but it did lack of compliate filter cases,
like "I want to get containers name is jack or id=7d1", it could work around use
(get id=7d1 containers' name and get name=jack containers, and then construct the
final containers, they could be done in user side use shell or rest API)
2) Fix one network filter bug which could include duplicate result
when use -f name= -f id=, it would get duplicate results
3) Make id filter same as container id filter, which means match any string.
not use prefix match.
It is for consistent match logic

The documentation already says the cache miss happens only at `ARG`
variable usage, not declaration, but there is a very common implicit
usage: `RUN`, which this commit documents even more, improving on #21790.
Also, use `definition` instead of `declaration`: it's the same thing, and
`definition` is already used in this documentation, contrary to
`declaration`.
Also, distinguish between "instructions" and "variables defined by `ARG`
instructions".

This fix tries to fix the discrepancy between `docker stats` and
`docker run` where `docker run` uses RAMInBytes for all memory
related inputs but `docker stats` uses HumanSize for all memory
related outputs.
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.

Once thin pool gets full, bad things can happen. 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.

Following #19995 and #17409 this PR enables skipping userns re-mapping

The feature is enabled by specifying ```--userns:host```, which will not
