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)
...
With this patch:
docker images --help
Usage: docker images [OPTIONS] [REPOSITORY[:TAG]]
List images
Aliases:
docker image ls, docker image list, docker images
Options:
-a, --all Show all images (default hides intermediate images)

- Prevent completion on "create" subcommands to prevent them
from completing with local filenames
- Add completion for "docker image save"
- Add completion for "docker image tag"
- Disable completion for "docker login"
- Exclude "paused" containers for "docker container attach" and
"docker container exec"

This adds a new annotation to commands that are known to be frequently
used, and allows setting a custom weight/order for these commands to
influence in what order they appear in the --help output.
I'm not entirely happy with the implementation (we could at least use
some helpers for this, and/or make it more generic to group commands
in output), but it could be a start.
For now, limiting this to only be used for the top-level --help, but
we can expand this to subcommands as well if we think it makes sense
to highlight "common" / "commonly used" commands.

Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.
The changes were performed by the following script:
for f in $(git ls-files \*.go | grep -v ^vendor/); do
sed -i 's|golang.org/x/net/context|context|' $f
goimports -w $f
for i in 1 2; do
awk '/^$/ {e=1; next;}
/\t"context"$/ {e=0;}
{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
mv $f.new $f
goimports -w $f
done
done
[v2: do awk/goimports fixup twice]

It has been refactored to a hijackedIOStreamer type which has several
methods which are used to prepare input and handle streaming the input
and output separately.

The docker/client package was updated to support the updated Container
Wait API functionality. The run and start commands have been updated to
use the new wait features.

This is necessary in order to avoid execId leaks in the case where a
`docker exec -it` is run without a terminal available for the client.
You can reproduce this issue by running the following command many
times.
% nohup docker exec -it some_container true
The container `some_container` will have execIDs that will never
normally be cleaned up (because the client died before they were
started).
In addition, this patch adds a docker-inspect step to ensure that we
give "container does not exist" errors consistently.

Whitelist some existing offenders, and use a high limit for now.
This limit should decrese over time.
