Ian Campbell 7d0645c5fe Use command.Cli instead of command.DockerCli
The linter is complaining:

    cmd/docker/docker.go:72:23⚠️ dockerCli can be github.com/docker/cli/cli/command.Cli (interfacer)

Unclear precisely which change in the preceeding commits caused it to notice
this possibility.

Tibor Vass 1ed02c40fe cli-plugins: alias an existing allowed command (only builder for now)
With this patch it is possible to alias an existing allowed command.
At the moment only builder allows an alias.

This also properly puts the build command under builder, instead of image
where it was for historical reasons.

Ian Campbell 8c087b6a1e cmd/docker: only parse global arguments once.
Before calling `cmd.Execute` we need to reset the arguments to be used to not
include the global arguments which we have already parsed. This is precisely
the `args` which we have in our hand at this point.

This fixes `TestGlobalArgsOnlyParsedOnce/builtin` in the cli-plugins e2e tests.

`TestGlobalArgsOnlyParsedOnce/plugin` is still broken will be fixed next.

Ian Campbell d4ced2ef77 allow plugins to have argument which match a top-level flag.
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.

Basic framework for writing and running CLI plugins
2019-01-31 17:44:46 +01:00
Ian Campbell baabf6e8ad Ensure that plugins are only listed once in help outputs.
They were listed twice in `docker --help` (but not `docker help`), since the
stubs were added in both `tryRunPluginHelp` and the `setHelpFunc` closure.

Calling `AddPluginStubCommands` earlier in `setHelpFunc` before the call to
`tryRunPluginHelp` is sufficient. Also it is no longer necessary to add just
valid plugins (`tryRunPluginHelp` handles invalid plugins correctly) so remove
that logic (which was in any case broken for e.g. `docker --help`).

Update the e2e test to check for duplicate entries and also to test `docker
--help` which was previously missed.

Ian Campbell 935d47bbe9 Ignore unknown arguments on the top-level command.
This allows passing argument to plugins, otherwise they are caught by the parse
loop, since cobra does not know about each plugin at this stage (to avoid
having to always scan for all plugins) this means that e.g. `docker plugin
--foo` would accumulate `plugin` as an arg to the `docker` command, then choke
on the unknown `--foo`.

This allows unknown global args only, unknown arguments on subcommands (e.g.
`docker ps --foo`) are still correctly caught.

Add an e2e test covering this case.

Ian Campbell 158a766886 Fold `dockerPreRun` into `DockerCli.Initialize`
All of the current callers follow the pattern:

    dockerPreRun(opts)
    err := dockerCli.Initialize(opts) ...

So there is no semantic change into merging the content of `dockerPreRun` into the head of `Initialize`.

I'm about to add a new caller outside of the `cmd/docker` package and this
seems preferable exporting `DockerPreRun`.

Mark checkpoint feature as Linux-only, and homogenize error messages
This patch adds annotations to mark the checkpoint commands as Linux only, which
hides them if the daemon is running a non-matching operating-system type;

Before:

    docker

    Usage:	docker COMMAND

    A self-sufficient runtime for containers

    ...

    Management Commands:
      config      Manage Docker configs
      container   Manage containers
      image       Manage images

After:

    docker

    Usage:	docker COMMAND

    A self-sufficient runtime for containers

    ...

    Management Commands:
      checkpoint  Manage checkpoints
      config      Manage Docker configs
      container   Manage containers
      image       Manage images

This change also prints errors when attempting to use checkpoint commands or
flags if the feature is not supported by the Daemon's operating system;

    $ docker checkpoint --help
    docker checkpoint is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows

    $ docker checkpoint create --help
    docker checkpoint create is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows

    $ docker checkpoint ls --help
    docker checkpoint ls is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows

    $ docker checkpoint rm --help
    docker checkpoint rm is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows

    $ docker container start --checkpoint=foo mycontainer
    "--checkpoint" requires the Docker daemon to run on linux, but the Docker daemon is running on windows

    $ docker container start --checkpoint-dir=/foo/bar mycontainer
    "--checkpoint-dir" requires the Docker daemon to run on linux, but the Docker daemon is running on windows

After this change:

    docker run
    "docker run" requires at least 1 argument.
    See 'docker run --help'.

    Usage:  docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

    Run a command in a new container
