Fixes#4648
Make it easier to specify IPv6 addresses in the '--add-host' option by
permitting 'host=ip' in addition to 'host:ip', and allowing square
brackets around the address.
For example:
--add-host=my-hostname:127.0.0.1
--add-host=my-hostname:::1
--add-host=my-hostname=::1
--add-host=my-hostname:[::1]
To avoid compatibility problems, the CLI will replace an '=' separator
with ':', and strip brackets, before sending the request to the API.

This attempts to make it clearer that the --cgroup-parent option is only used
for the containers used during build. Instead of mentioning "build container",
I opted for using "RUN instructions" (to match the --network description),
although this may not be ideal (as it assumes the "Dockerfile" front-end, which
of course may not be the case).

Keep frontmatter for docker, dockerd and index markdown files.
Also needs to move cli.md > docker.md before generation and
then move it back because cli.md is needed for yaml generation on docs

Cobra allows for aliases to be defined for a command, but only allows these
to be defined at the same level (for example, `docker image ls` as alias for
`docker image list`). Our CLI has some commands that are available both as a
top-level shorthand as well as `docker <object> <verb>` subcommands. For example,
`docker ps` is a shorthand for `docker container ps` / `docker container ls`.
This patch introduces a custom "aliases" annotation that can be used to print
all available aliases for a command. While this requires these aliases to be
defined manually, in practice the list of aliases rarely changes, so maintenance
should be minimal.
As a convention, we could consider the first command in this list to be the
canonical command, so that we can use this information to add redirects in
our documentation in future.
Before this patch:
docker images --help
Usage: docker images [OPTIONS] [REPOSITORY[:TAG]]
List images
Options:
-a, --all Show all images (default hides intermediate images)
...

Looks like the YAML conversion doesn't like lines starting with `[`, and
causing it to use the "compact" formatting in the generated YAML.
This patch un-wraps these lines to prevent this.

The `ENV key value` form can be ambiguous, for example, the following defines
a single env-variable (`ONE`) with value `"TWO= THREE=world"`:
ENV ONE TWO= THREE=world
While we cannot deprecate/remove that syntax (as it would break existing
Dockerfiles), we should reduce exposure of the format in our examples.

Unlike GitHub's web-UI, the "rouge" hightlighter used in our
online documentation is case-sensitive. As a result, code-blocks
having the Dockerfile (uppercase) code-hint were not highlighted.
This changes those to use lowercase, which is supported by both.

If the markdown contains trailing spaces, or has tabs included,
the YAML generator uses a compact format for the text (using `\n`
and `\t`, instead of plain newlines).
The compact format makes it difficult to review changes in the
yaml docs when vendoring in the documentation repository.
This patch:
- removes trailing whitespace
- replaces tabs for spaces
- fixes some minor formatting and markdown issues

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
