This is less of a layering violation and removes some ugly hardcoded
`"kubernetes"` strings which were needed to avoid an import loop.
Signed-off-by: Ian Campbell <ijc@docker.com>
This removes the need for the core context code to import
`github.com/docker/cli/cli/context/kubernetes` which in turn reduces the
transitive import tree in this file to not pull in all of Kubernetes.
Note that this means that any calling code which is interested in the
kubernetes endpoint must import `github.com/docker/cli/cli/context/kubernetes`
itself somewhere in order to trigger the dynamic registration. In practice
anything which is interested in Kubernetes must import that package (e.g.
`./cli/command/context.list` does for the `EndpointFromContext` function) to do
anything useful, so this restriction is not too onerous.
As a special case a small amount of Kubernetes related logic remains in
`ResolveDefaultContext` to handle error handling when the stack orchestrator
includes Kubernetes. In order to avoid a circular import loop this hardcodes
the kube endpoint name.
Similarly to avoid an import loop the existing `TestDefaultContextInitializer`
cannot continue to unit test for the Kubernetes case, so that aspect of the
test is carved off into a very similar test in the kubernetes context package.
Lastly, note that the kubernetes endpoint is now modifiable via
`WithContextEndpointType`.

These are needed by any dynamically registered (via

test.
Signed-off-by: Ian Campbell <ijc@docker.com>
Previously an endpoint registered using `RegisterDefaultStoreEndpoints` would
not be taken into consideration by `resolveDefaultContext` and so could not
provide any details.
Resolve this by passing a `store.Config` to `resolveDefaultContext` and using
it to iterate over all registered endpoints. Any endpoint can ensure that their
type implements the new `EndpointDefaultResolver` in order to provide a default.
The Docker and Kubernetes endpoints are special cased, shortly the Kubernetes
one will be refactored to be dynamically registered.

The comment on `github.com/docker/cli/kubernetes.NewKubernetesConfig` said:
// Deprecated: Use github.com/docker/compose-on-kubernetes/api.NewKubernetesConfig instead
By making this switch in `github.com/docker/cli/context/kubernetes/load.go` we
break a vendoring chain:
`github.com/docker/cli/cli/command`
→ `vendor/github.com/docker/cli/cli/context/kubernetes/load.go`
→ `vendor/github.com/docker/cli/kubernetes`
→ `github.com/docker/compose-on-kubernetes/api/compose/...`
This means that projects which just want `github.com/docker/cli/cli/command`
(which is itself pulled in transitively by
`github.com/docker/cli/cli-plugins/plugin`) which do not themselves need the
compose-on-kubernetes API avoid a huge pile of transitive dependencies.

This refactors the way networking options are parsed, and makes the

daemon does not yet accept multiple networks when creating a container,
and will produce an error.
For backward-compatibility, the following global networking-related
options are associated with the first network (in case multiple
networks are set);
- `--ip`
- `--ip6`
- `--link`
- `--link-local-ip`
- `--network-alias`
Not all of these options are supported yet in the advanced notation,
but for options that are supported, setting both the per-network option
and the global option will produce a "conflicting options" error.

In the initial implementation I thought it would be good to not pass on the
deprecation to plugins (since they are new). However it turns out this causes
`docker helloworld -h` to print a spurious "pflag: help requested" line:
$ docker helloworld -h
pflag: help requested
See 'docker helloworld --help'.
Usage: docker helloworld [OPTIONS] COMMAND
A basic Hello World plugin for tests
...
Compared with:
$ docker ps -h
Flag shorthand -h has been deprecated, please use --help
Usage: docker ps [OPTIONS]
This is in essence because having the flag undefined hits a different path
within cobra, causing `c.execute()` to return early due to getting an error
(`flag.ErrHelp`) from `c.ParseFlags`, which launders the error through our
`FlagErrorFunc` which wraps it in a `StatusError` which in turn defeats an `if
err == flag.ErrHelp` check further up the call chain. If the flag is defined we
instead hit a path which returns a bare `flag.ErrHelp` without wrapping it.
I considered updating our `FlagErrorFunc` to not wrap `flag.ErrHelp` (and then
following the chain to the next thing) however while doing that I realised that
the code for `-h` (and `--help`) is deeply embedded into cobra (and its flags
library) such that actually using `-h` as a plugin argument meaning something
other than `help` is basically impossible/impractical. Therefore we may as well
have plugins behave identically to the monolithic CLI and support (deprecated)
the `-h` argument.
With this changed the help related blocks of `SetupRootCommand` and
`SetupPluginRootCommand` are now identical, so consolidate into
`setupCommonRootCommand`.
Tests are updated to check `-h` in a variety of scenarios, including the happy
case here.

As pointed out in #1459, docker cli fails to detect that the input is a tarball,
in case it is generated by `git archive --format=tgz`.
This happens because `git archive` adds some metadata to the initial tar header,
and so it is more than 1 block (of 512 bytes) long, while we only provide 1 block
to archive/tar.Next() and it fails.
To fix, give it 2 blocks :)

This adds validation to `docker container run` / `docker container create`;
Validation of labels provided through flags was removed in 31dc5c0a9a,
after the validation was changed to fix labels without values, and to prevent
labels from being expanded with environment variables in 2b17f4c8a8
However, now empty label names from _files_ (`--label-file`) followed different
validation rules than labels passed through `--label`.
This patch adds back minimal validation for labels passed through the command-line
Before this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \
busybox
docker container inspect --format '{{json .Config.Labels}}' label
```
```json
{
"": "with-leading-equal-sign",
" ": " ",
"somelabel": "somevalue",
"with\"quotes\"in-key": "test",
"with-quotes-in-value": "{\"foo\"}",
"without-value": ""
}
```
After this patch:
```bash
docker container create \
--name label \
--label==with-leading-equal-sign \
--label=without-value \
--label=somelabel=somevalue \
--label " = " \
--label=with-quotes-in-value='{"foo"}' \
--label='with"quotes"in-key=test' \

This patch fixes a bug where labels use the same behavior as `--env`, resulting
in a value to be copied from environment variables with the same name as the
label if no value is set (i.e. a simple key, no `=` sign, no value).
An earlier pull request addressed similar cases for `docker run`;
2b17f4c8a8, but this did not address the
same situation for (e.g.) `docker service create`.
Digging in history for this bug, I found that use of the `ValidateEnv`
function for labels was added in the original implementation of the labels feature in
abb5e9a077 (diff-ae476143d40e21ac0918630f7365ed3cR34)
However, the design never intended it to expand environment variables,
and use of this function was either due to either a "copy/paste" of the
equivalent `--env` flags, or a misunderstanding (the name `ValidateEnv` does
not communicate that it also expands environment variables), and the existing
`ValidateLabel` was designed for _engine_ labels (which required a value to
be set).
Following the initial implementation, other parts of the code followed
the same (incorrect) approach, therefore leading the bug to be introduced
in services as well.
This patch:
- updates the `ValidateLabel` to match the expected validation
rules (this function is no longer used since 31dc5c0a9a),
and the daemon has its own implementation)
- corrects various locations in the code where `ValidateEnv` was used instead of `ValidateLabel`.
Before this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker service inspect --format '{{json .Spec.Labels}}' test
{"SOME_ENV_VAR":"I_AM_SOME_ENV_VAR"}
```
After this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker container inspect --format '{{json .Config.Labels}}' test
{"SOME_ENV_VAR":""}

The issue with plugin options clashing with globals is that when cobra is
parsing the command line and it comes across an argument which doesn't start
with a `-` it (in the absence of plugins) distinguishes between "argument to
current command" and "new subcommand" based on the list of registered sub
commands.
Plugins breaks that model. When presented with `docker -D plugin -c foo` cobra
parses up to the `plugin`, sees it isn't a registered sub-command of the
top-level docker (because it isn't, it's a plugin) so it accumulates it as an
argument to the top-level `docker` command. Then it sees the `-c`, and thinks
it is the global `-c` (for AKA `--context`) option and tries to treat it as
that, which fails.
In the specific case of the top-level `docker` subcommand we know that it has
no arguments which aren't `--flags` (or `-f` short flags) and so anything which
doesn't start with a `-` must either be a (known) subcommand or an attempt to
execute a plugin.
We could simply scan for and register all installed plugins at start of day, so
that cobra can do the right thing, but we want to avoid that since it would
involve executing each plugin to fetch the metadata, even if the command wasn't
going to end up hitting a plugin.
Instead we can parse the initial set of global arguments separately before
hitting the main cobra `Execute` path, which works here exactly because we know
that the top-level has no non-flag arguments.
One slight wrinkle is that the top-level `PersistentPreRunE` is no longer
called on the plugins path (since it no longer goes via `Execute`), so we
arrange for the initialisation done there (which has to be done after global
flags are parsed to handle e.g. `--config`) to happen explictly after the
global flags are parsed. Rather than make `newDockerCommand` return the
complicated set of results needed to make this happen, instead return a closure
which achieves this.
The new functionality is introduced via a common `TopLevelCommand` abstraction
which lets us adjust the plugin entrypoint to use the same strategy for parsing
the global arguments. This isn't strictly required (in this case the stuff in
cobra's `Execute` works fine) but doing it this way avoids the possibility of
subtle differences in behaviour.
Fixes#1699, and also, as a side-effect, the first item in #1661.

This means that plugins can use whatever methods the monolithic CLI supports,
which is good for consistency.
This relies on `os.Args[0]` being something which can be executed again to
reach the same binary, since it is propagated (via an envvar) to the plugin for
this purpose. This essentially requires that the current working directory and
path are not modified by the monolithic CLI before it launches the plugin nor
by the plugin before it initializes the client. This should be the case.
Previously the fake apiclient used by `TestExperimentalCLI` was not being used,
since `cli.Initialize` was unconditionally overwriting it with a real one
(talking to a real daemon during unit testing, it seems). This wasn't expected
nor desirable and no longer happens with the new arrangements, exposing the
fact that no `pingFunc` is provided, leading to a panic. Add a `pingFunc` to
the fake client to avoid this.

A while ago, Docker split the "Domainname" field out from the "Hostname"
field for the container configuration. There was no real user-visible
change associated with this (and under the hood "Domainname" was mostly
left unused from the command-line point of view). We now add this flag
in order to match other proposed changes to allow for setting the NIS
domainname of a container.
This also includes a fix for the --hostname parsing tests (they would
not error out if only one of .Hostname and .Domainname were incorrectly
set -- which is not correct).

- make it possible to extract the formatter implementation from the

- extract some formatter into their own packages
This is essentially moving the "formatter" implementation of each type
in their respective packages. The *main* reason to do that, is to be
able to depend on `cli/command/formatter` without depending of the
implementation detail of the formatter. As of now, depending on
`cli/command/formatter` means we depend on `docker/docker/api/types`,
`docker/licensing`, … — that should not be the case. `formatter`
should hold the common code (or helpers) to easily create formatter,

Unlike `docker build --secret`, `docker build --ssh` allows the build container to
use SSH keys with passphrases.
$ eval $(ssh-agent)
$ ssh-add ~/.ssh/id_rsa
(Input your passphrase here)
$ docker build --ssh default=$SSH_AUTH_SOCK ...
This feature requires the daemon with `CapExecMountSSH` build capability (moby/moby#37973) .
Currently, the official Dockerfile frontend does not provide the syntax for using the SSH forwarder.
However, the experimental `RUN --mount=type=ssh` syntax can be enabled by using
the Dockerfile frontend image built with the `BUILDTAGS="dfrunmount dfssh"`, via the `# syntax =` "shebang".
The Dockerfile for the Dockerfile frontend is available at github.com/moby/buildkit/frontend/dockerfile/cmd/dockerfile-frontend)
The pre-built image is also available as `tonistiigi/dockerfile:ssh20181002` .
An example Dockerfile with `RUN --mount=type=ssh`:
# syntax = tonistiigi/dockerfile:ssh20181002
FROM alpine
RUN apk add --no-cache openssh-client
RUN mkdir -p -m 0700 ~/.ssh && ssh-keyscan gitlab.com >> ~/.ssh/known_hosts
RUN --mount=type=ssh ssh git@gitlab.com | tee /hello
# "Welcome to GitLab, @GITLAB_USERNAME_ASSOCIATED_WITH_SSHKEY" should be printed here

2. If a --ca-cert flag is provided, require a --ca-key or --external-ca flag be
provided as well, otherwise either the server will say that the request is
invalid, or if there was previously an external CA corresponding to the cert, it
will succeed. While that works, it's better to require the user to explicitly

Removing a host by `<host>:<ip>` should only remove occurences of the host with
a matching IP-address, instead of removing all entries for that host.
In addition, combining `--host-rm` and `--host-add` for the same host should
result in the new host being added.
This patch fixes the way the diff is calculated to allow combining
removing/adding, and to support entries having both a canonical, and aliases.
Aliases cannot be added by the CLI, but are supported in the Service spec, thus
should be taken into account:
Entries can be removed by either a specific `<host-name>:<ip-address>`
mapping, or by `<host>` alone:
- If both IP-address and host-name is provided, only remove the hostname
from entries that match the given IP-address.
- If only a host-name is provided, remove the hostname from any entry it
is part of (either as _canonical_ host-name, or as _alias_).
- If, after removing the host-name from an entry, no host-names remain in
the entry, the entry itself should be removed.
For example, the list of host-entries before processing could look like this:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host1 host4",
"127.0.0.3 host1",
"127.0.0.1 host1",
}
Removing `host1` removes every occurrence:
hosts = &[]string{
"127.0.0.2 host3 host2 host4",
"127.0.0.1 host4",
}
Whereas removing `host1:127.0.0.1` only remove the host if the IP-address matches:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host4",
"127.0.0.3 host1",
}
Before this patch:
$ docker service create --name my-service --host foo:127.0.0.1 --host foo:127.0.0.2 --host foo:127.0.0.3 nginx:alpine
$ docker service update --host-rm foo:127.0.0.1 --host-add foo:127.0.0.4 my-service
$ docker service inspect --format '{{.Spec.TaskTemplate.ContainerSpec.Hosts}}' my-service
[]

Historically, the Dockerfile had to be insde the build-context, because it was
sent as part of the build-context.
3f6dc81e10
added support for passing the Dockerfile through stdin, in which case the
contents of the Dockerfile is injected into the build-context.
This patch uses the same mechanism for situations where the location of the
Dockerfile is passed, and its path is outside of the build-context.
Before this change:
$ mkdir -p myproject/context myproject/dockerfiles && cd myproject
$ echo "hello" > context/hello
$ echo -e "FROM busybox\nCOPY /hello /\nRUN cat /hello" > dockerfiles/Dockerfile
$ docker build --no-cache -f $PWD/dockerfiles/Dockerfile $PWD/context
unable to prepare context: the Dockerfile (/Users/sebastiaan/projects/test/dockerfile-outside/myproject/dockerfiles/Dockerfile) must be within the build context
After this change:
$ mkdir -p myproject/context myproject/dockerfiles && cd myproject

When adding a network using `docker service update --network-add`,
the new network was added by _name_.
Existing entries in a service spec are listed by network ID, which
resulted in the CLI not detecting duplicate entries for the same
network.
This patch changes the behavior to always use the network-ID,
so that duplicate entries are correctly caught.
Before this change;
$ docker network create -d overlay foo
$ docker service create --name=test --network=foo nginx:alpine

$ docker service inspect --format '{{ json .Spec.TaskTemplate.Networks}}' test

Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).
