This test is very flaky, the retry loop runs for 550ms and some more, 750ms is
cleary not enough for everything to set and for the cli to return the tty resize

finish.

The code is similar to that used by the volume rm subcommand, however,
one difference I noticed was VolumeRemove takes the force flag/option
was a parameter. This isn't the case for NetworkRemove.
To get NetworkRemove to take a similar parameter, this would require
modifying the Docker daemon. For now this isn't a route I wish to take
when the code can be arrange to mimic the same behavior.

pkg/urlutil (despite its poorly chosen name) is not really intended as a
generic utility to handle URLs, and should only be used by the builder to
handle (remote) build contexts.
The `IsURL()` function only does a very rudimentary check for `http(s)://`
prefixes, without any other validation, but due to its name may give
incorrect expectations.
As we're deprecating this package for uses other than for build-contexts,
this patch replaces this instance of the utility for a local function.
While changing, also cleaned up some intermediate variables, and made
the logic slightly more descriptive.

This adds a new annotation to commands that are known to be frequently

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

The CLI currenly calls the `/info` endpoint to get the address
of the default registry to use.
This functionality was added as part of the initial Windows implementation
of the engine. For legal reasons, Microsoft Windows (and thus Docker images
based on Windows) were not allowed to be distributed through non-Microsoft
infrastructure. As a temporary solution, a dedicated "registry-win-tp3.docker.io"
registry was created to serve Windows images.
As a result, the default registry was no longer "fixed", so a helper function
(`ElectAuthServer`) was added to allow the CLI to get the correct registry
address from the daemon. (docker/docker PR's/issues 18019, 19891, 19973)
Using separate registries was not an ideal solution, and a more permanent
solution was created by introducing "foreign image layers" in the distribution
spec, after which the "registry-win-tp3.docker.io" ceased to exist, and
removed from the engine through docker/docker PR 21100.
However, the `ElectAuthServer` was left in place, quoting from that PR;
> make the client check which default registry the daemon uses is still
> more correct than leaving it up to the client, even if it won't technically
> matter after this PR. There may be some backward compatibility scenarios
> where `ElectAuthServer` [sic] is still helpful.
That comment was 5 years ago, and given that the engine and cli are
released in tandem, and the default registry is not configurable, we
can save the extra roundtrip to the daemon by using a fixed value.
This patch deprecates the `ElectAuthServer` function, and makes it
return the default registry without calling (potentially expensie)
`/info` API endpoint.

Once upon a time, there was a website named ["The Docker index"][2]; a complimentary
service for users of Docker, provided by dotCloud. The Docker Index was the place
to find and explore pre-made container images, and allowed you to [share your
images and download them][1]. The Docker Index evolved rapidly, and gained new
features, such as [Trusted Images][3], and "stars" to rank your favorite images.
The website also provided an API, which allowed you to search images, even from
the comfort of your `docker` CLI. Things moved fast in container-land, and while
there was an API to use, it was still a work in progress. While the Docker Index
allowed users to "star" images, the search API did not rank results accordingly.
As any engineer knows, there's no problem that can't be solved with some elbow-
grease and a piece of Duct tape, so while the Docker Index team worked on making
the search API better, the `docker` engine [fixed the problem on the client side][4]
Years went by, and the Docker Index API became the "registry V1" specification,
including search. The registry got a major "v2" rewrite and became the [OCI Distribution
Spec][5], and Docker Index became Docker Hub, which included V2 and V3 search APIs.
The V1 search API continued to be supported, as it was the only documented API
for registries, but improvements were made, including ranking of search results.
Duct tape is durable, and even though improvements were made, the Docker client
continued to sort the results as well. Unfortunately, this meant that search
results on the command-line were ranked different from their equivalent on the
registry (such as Docker Hub).
This patch removes the client-side sorting of results, using the order in which
the search API returned them to (finally) celebrate the work of the engineers
working on the search API, also when used from the command-line.

This feature allowed using an encrypted private key with a supplied password,
but did not provide additional security as the encryption is known to be broken,
and the key is sitting next to the password in the filesystem. Users are recommended

The DefaultStopSignal const has been deprecated, because the daemon already
handles a default value. The current code did not actually send the default
value unless the flag was set, which also made the flag description incorrect,

potentially be different as was specified here.

Commit 73aef6edfe
modified archive.ReplaceFileTarWrapper to set the Name field in the tar header,
if the field was not set.
That change exposed an issue in how a Dockerfile from stdin was sent to the daemon.
When attempting to build using a build-context, and a Dockerfile from stdin, the
following happened:
```bash
mkdir build-stdin && cd build-stdin && echo hello > hello.txt
DOCKER_BUILDKIT=0 docker build --no-cache -t foo -f- . <<'EOF'
FROM alpine
COPY . .
EOF
Sending build context to Docker daemon 2.607kB
Error response from daemon: dockerfile parse error line 1: unknown instruction: .DOCKERIGNORE
```
Removing the `-t foo`, oddly lead to a different failure:
```bash
DOCKER_BUILDKIT=0 docker build --no-cache -f- . <<'EOF'
FROM alpine
COPY . .
EOF
Sending build context to Docker daemon 2.581kB
Error response from daemon: Cannot locate specified Dockerfile: .dockerfile.701d0d71fb1497d6a7ce
```
From the above, it looks like the tar headers got mangled, causing (in the first
case) the daemon to use the build-context tar as a plain-text file, and therefore
parsing it as Dockerfile, and in the second case, causing it to not being able to
find the Dockerfile in the context.
I noticed that both TarModifierFuncs were using the same `hdrTmpl` struct, which
looks to caused them to step on each other's toes. Changing them to each initialize
their own struct made the issue go away.
After this change:
```bash
DOCKER_BUILDKIT=0 docker build --no-cache -t foo -f- . <<'EOF'
FROM alpine
COPY . .
EOF

The docker info output contains both "local" and "remote" (daemon-side) information.
The API endpoint to collect daemon information (`/info`) is known to be "heavy",
and (depending on what information is needed) not needed.
This patch checks if the template (`--format`) used requires information from the
daemon, and if not, omits making an API request.
This will improve performance if (for example), the current "context" is requested
from `docker info` or if only plugin information is requested.

Commit 330a003533
introduced "synchronous" service update and rollback, using progress bars to show
current status for each task.
As part of that change, progress bars were "reversed" when doing a rollback, to
indicate that status was rolled back to a previous state.
Reversing direction is somewhat confusing, as progress bars now return to their
"initial" state to indicate it was "completed"; for an "automatic" rollback, this
may be somewhat clear (progress bars "move to the right", then "roll back" if the
update failed), but when doing a manual rollback, it feels counter-intuitive
(rolling back is the _expected_ outcome).
This patch removes the code to reverse the direction of progress-bars, and makes
progress-bars always move from left ("start") to right ("finished").
Before this patch
----------------------------------------
1. create a service with automatic rollback on failure
$ docker service create --update-failure-action=rollback --name foo --tty --replicas=5 nginx:alpine

2. update the service, making it fail after 3 seconds

2/5: running [==================================================>]
3/5: starting [============================================> ]
4/5: running [==================================================>]
5/5: running [==================================================>]
3. Once the service starts failing, automatic rollback is started; progress-bars now move in the reverse direction;

1/5: ready [===========> ]
2/5: ready [===========> ]
3/5: running [> ]
4/5: running [> ]

4. When the rollback is completed, the progressbars are at the "start" to indicate they completed;

After this patch
----------------------------------------
Progress bars always go from left to right; also in a rollback situation;
After updating to the "faulty" entrypoint, task are deployed:
$ docker service update --entrypoint="/bin/sh -c 'sleep 3; exit 1'" foo

Once tasks start failing, rollback is started, and presented the same as a regular
update; progress bars go from left to right;

We refactorted `ForwardAllSignals` so it blocks but did not update the
call in `start` to call it in a goroutine.
Signed-off-by: Brian Goff <cpuguy83@gmail.com>
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.
With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;
Unsupported signal: <nil>. Discarding.
To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;
```patch

We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":

On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.
However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.
Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

Prior to this change, progressbars would sometimes be hidden, and the function
would return early. In addition, the direction of the progressbars would sometimes
be "incrementing" (similar to "docker service update"), and sometimes be "decrementing"
(to indicate a "rollback" is being performed).
This fix makes sure that we always proceed with the "verifying" step, and now
prints a message _after_ the verifying stage was completed;

Commit f32731f902 fixed a potential panic

However, other code paths currently use the result of `GetDefaultAuthConfig()`
even in an error condition; this resulted in a panic, because a `nil` was

This hack was added in an attempt to continue supporting the experimental
(non-buildkit) `--platform` option, by dynamically updating the API version
required if buildkit isn't enabled.
This hack didn't work, however, because at the moment the override is
added, the command is not yet attached to the "root" (`docker`) command,
and because of that, the command itself is the `root` command;
`cmd.Root()` returned the `build` command.
As a result, validation steps defined as `PersistentPreRunE` on the root
command were not executed, causing invalid flags/options to not producing
an error.
Attempts to use an alternative approach (for example, cobra supports both
a `PersistentPreRun` and `PersistentPreRunE`) did not work either, because
`PersistentPreRunE` takes precedence over `PersistentPreRun`, and only one
will be executed.
Now that `--platform` should be supported for other cases than just for
experimental (LCOW), let's remove the 'experimental' check, and just assume
it's supported for API v1.32 and up.

The CLI disabled experimental features by default, requiring users
to set a configuration option to enable them.
Disabling experimental features was a request from Enterprise users
that did not want experimental features to be accessible.
We are changing this policy, and now enable experimental features
by default. Experimental features may still change and/or removed,
and will be highlighted in the documentation and "usage" output.
For example, the `docker manifest inspect --help` output now shows:
EXPERIMENTAL:
docker manifest inspect is an experimental feature.
Experimental features provide early access to product functionality. These features
may change between releases without warning or can be removed entirely from a future
release. Learn more about experimental features: https://docs.docker.com/go/experimental/

Adding/removing capabilities when updating a service is considered a tri-state;
- if the capability was previously "dropped", then remove it from "CapabilityDrop",
but do NOT add it to "CapabilityAdd". However, if the capability was not yet in
the service's "CapabilityDrop", then simply add it to the service's "CapabilityAdd"
- likewise, if the capability was previously "added", then remove it from
"CapabilityAdd", but do NOT add it to "CapabilityDrop". If the capability was
not yet in the service's "CapabilityAdd", then simply add it to the service's
"CapabilityDrop".
In other words, given a service with the following:
| CapDrop | CapAdd |
| -------------- | ------------- |
| CAP_SOME_CAP | |
When updating the service, and applying `--cap-add CAP_SOME_CAP`, the previously
dropped capability is removed:
| CapDrop | CapAdd |
| -------------- | ------------- |

When updating the service a second time, applying `--cap-add CAP_SOME_CAP`,
capability is now added:
| CapDrop | CapAdd |
| -------------- | ------------- |
| | CAP_SOME_CAP |

When creating and updating services, we need to avoid unneeded service churn.
The interaction of separate lists to "add" and "drop" capabilities, a special
("ALL") capability, as well as a "relaxed" format for accepted capabilities
(case-insensitive, `CAP_` prefix optional) make this rather involved.
This patch updates how we handle `--cap-add` / `--cap-drop` when _creating_ as
well as _updating_, with the following rules/assumptions applied:
- both existing (service spec) and new (values passed through flags or in
the compose-file) are normalized and de-duplicated before use.
- the special "ALL" capability is equivalent to "all capabilities" and taken
into account when normalizing capabilities. Combining "ALL" capabilities
and other capabilities is therefore equivalent to just specifying "ALL".
- adding capabilities takes precedence over dropping, which means that if
a capability is both set to be "dropped" and to be "added", it is removed
from the list to "drop".
- the final lists should be sorted and normalized to reduce service churn
- no validation of capabilities is handled by the client. Validation is
delegated to the daemon/server.
When deploying a service using a docker-compose file, the docker-compose file
is *mostly* handled as being "declarative". However, many of the issues outlined
above also apply to compose-files, so similar handling is applied to compose
files as well to prevent service churn.

When using `docker rm` / `docker container rm` with the `-f` / `--force` option, attempts to remove non-existing containers should print a warning, but should return a zero exit code ("successful").
Currently, a non-zero exit code is returned, marking the removal as "failed";
$ docker rm -fv 798c9471b695
Error: No such container: 798c9471b695
$ echo $?
1
The command should match the behavior of `rm` / `rm -f`, with the exception that
a warning is printed (instead of silently ignored):
Running `rm` with `-f` silences output and returns a zero exit code:
touch some-file && rm -f no-such-file some-file; echo exit code: $?; ls -la
# exit code: 0
# total 0
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..
mkdir some-directory && rm -rf no-such-directory some-directory; echo exit code: $?; ls -la
# exit code: 0
# total 0
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..
Note that other reasons for a delete to fail should still result in a non-zero
exit code, matching the behavior of `rm`. For instance, in the example below,
the `rm` failed because directories can only be removed if the `-r` option is used;
touch some-file && mkdir some-directory && rm -f some-directory no-such-file some-file; echo exit code: $?; ls -la
# rm: some-directory: is a directory
# exit code: 1
# total 0
# drwxr-xr-x 3 sebastiaan staff 96 Aug 14 14:15 .
# drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 ..

Combining `-add` and `-rm` flags on `docker service update` should
be usable to explicitly replace existing options. The current order
of processing did not allow this, causing the `-rm` flag to remove
properties that were specified in `-add`. This behavior was inconsistent
with (for example) `--host-add` and `--host-rm`.
This patch updates the behavior to first remove properties, then
add new properties.
Note that there's still some improvements to make, to make the removal
more granulas (e.g. to make `--label-rm label=some-value` only remove
the label if value matches `some-value`); these changes are left for
a follow-up.

Previously, if a registry AuthInfo was not present in the CLI config file, docker logout could not be used
to ask the credential helper to forget about it. It causes problem for people working with
multiple alternative config files, and it causes problems for cases like Docker Desktop w/ WSL 2, as
it uses the same win32 credential helper as the Windows CLI, but a different config file, leading to
bugs where I cannot logout from a registry from wsl2 if I logged in from Windows and vice-versa.

This adds the currently selected "docker context" to the output
of "docker version", which allows users to see which context
is selected to produce the version output, and can be used (for
example), to set the prompt to the currently selected context:
(in `~/.bashrc`):
```bash
function docker_context_prompt() {
PS1="context: $(docker version --format='{{.Client.Context}}')> "
}
PROMPT_COMMAND=docker_context_prompt
```
After reloading the `~/.bashrc`, the prompt now shows the currently selected
`docker context`:
```bash
$ source ~/.bashrc
context: default> docker context create --docker host=unix:///var/run/docker.sock my-context
my-context
Successfully created context "my-context"

* Added two new modes accepted by the `--mode` flag
* `replicated-job` creates a replicated job
* `global-job` creates a global job.
* When using `replicated-job` mode, the `replicas` flag sets the
`TotalCompletions` parameter of the job. This is the total number of
tasks that will run
* Added a new flag, `max-concurrent`, for use with `replicated-job`
mode. This flag sets the `MaxConcurrent` parameter of the job, which
is the maximum number of replicas the job will run simultaneously.
* When using `replicated-job` or `global-job` mode, using any of the
update parameter flags will result in an error, as jobs cannot be
updated in the traditional sense.
* Updated the `docker service ls` UI to include the completion status
(completed vs total tasks) if the service is a job.
* Updated the progress bars UI for service creation and update to
support jobs. For jobs, there is displayed a bar covering the overall
progress of the job (the number of tasks completed over the total
number of tasks to complete).
* Added documentation explaining the use of the new flags, and of jobs
in general.

- Perform feature detection when actually needed, instead of during
initializing
- Version negotiation is performed either when making an API request,
or when (e.g.) running `docker help` (to hide unsupported features)
- Use a 2 second timeout when 'pinging' the daemon; this should be
sufficient for most cases, and when feature detection failed, the
daemon will still perform validation (and produce an error if needed)
- context.WithTimeout doesn't currently work with ssh connections (connhelper),
so we're only applying this timeout for tcp:// connections, otherwise
keep the old behavior.

When printing services' tasks with `docker service ps` command, tasks are grouped only by task slot.
This leads to interleaving tasks from different services when `docker service ps` is called with multiple services.
Besides this, global services do not have slots at all and printing tasks for them doesn't group and
doesn't properly indent tasks with \_.
With this patch all tasks are grouped by service ID, slot and node ID (relevant only for global services) and it fixes issue 533.

The `docker push` command up until [v0.9.1](https://github.com/moby/moby/blob/v0.9.1/api/client.go#L998)
always pushed all tags of a given image, so `docker push foo/bar` would push (e.g.)
all of `foo/bar:latest`, `foo:/bar:v1`, `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see https://github.com/moby/moby/issues/3411 and the pull request that implemented
this: https://github.com/moby/moby/pull/4948).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image"
For example, in the following situation;
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
```
Running `docker push thajeztah/myimage` seemingly does the expected behavior (it
pushes `thajeztah/myimage:latest` to Docker Hub), however, it does not so for the
reason expected (`:latest` being the default tag), but because `:latest` happens
to be the only tag present for the `thajeztah/myimage` image.
If another tag exists for the image:
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
thajeztah/myimage v1.0.0 b534869c81f0 41 hours ago 1.22MB
```
Running the same command (`docker push thajeztah/myimage`) will push _both_ images
to Docker Hub.
> Note that the behavior described above is currently not (clearly) documented;
> the `docker push` reference documentation (https://docs.docker.com/engine/reference/commandline/push/)
does not mention that omitting the tag will push all tags
This patch changes the default behavior, and if no tag is specified, `:latest` is
assumed. To push _all_ tags, a new flag (`-a` / `--all-tags`) is added, similar
to the flag that's present on `docker pull`.
With this change:
- `docker push myname/myimage` will be the equivalent of `docker push myname/myimage:latest`
- to push all images, the user needs to set a flag (`--all-tags`), so `docker push --all-tags myname/myimage:latest`

Before this patch, using a template that used templating functions (such as
`lower` or `json`) caused the command to fail in the pre-processor step (in
`buildContainerListOptions`):
docker ps --format='{{upper .Names}}'
template: :1:8: executing "" at <.Names>: invalid value; expected string
This problem was due to the pre-processing using a different "context" type than
was used in the actual template, and custom functions to not be defined when
instantiating the Go template.
With this patch, using functions in templates works correctly:
docker ps --format='{{upper .Names}}'

The top-level `docker deploy` command (using the "Docker Application Bundle"
(`.dab`) file format was introduced as an experimental feature in Docker 1.13 /
17.03, but superseded by support for Docker Compose files.
With no development being done on this feature, and no active use of the file
format, support for the DAB file format and the top-level `docker deploy` command
(hidden by default in 19.03), is removed in this patch, in favour of `docker stack deploy`
using compose files.

Possible approach for client info
- split ClientInfo() into ClientInfo() and loadClientInfo()
- split ConfigFile() into ConfigFile() and loadConfigFile()
- ConfigFile() and ClientInfo() call their corresponding loadXX function
if it has not yet been loaded; this allows them to be used before
Initialize() was called.
- Initialize() *always* (re-)loads the configuration; this makes sure
that the correct configuration is used when actually calling commands.

Running `docker stack services <STACK> --orchestrator swarm would yield
the message "Noting found in stack: asdf" with an exit code 0. The same
command with kubernetes orchestrator would yield "nothing found in
stack: adsf" (note the lower-case "nothing") and a non-zero exit code.
This change makes the `stack services` command uniform for both
orchestrators. The logic of getting and printing services is split to
reuse the same formatting code.

API v1.41 adds a new option to get the number of desired
and running tasks when listing services. This patch enables
this functionality, and provides a fallback mechanism when
the ServiceStatus is not available, which would be when
using an older API version.
Now that the swarm.Service struct captures this information,
the `ListInfo` type is no longer needed, so it is removed,
and the related list- and formatting functions have been
modified accordingly.
To reduce repetition, sorting the services has been moved
to the formatter. This is a slight change in behavior, but
all calls to the formatter performed this sort first, so
the change will not lead to user-facing changes.

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`.

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.

// 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:

→ `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.

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

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' \
busybox
invalid argument "=with-leading-equal-sign" for "-l, --label" flag: invalid label format: "=with-leading-equal-sign"
```

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 warning, printed before running `docker system prune` was printing the
filters in JSON format.
This patch attempts to make the output human readable;
- updating the code, and template to print filters individually
- reducing the indentation (which was quite deep)
Before this patch was applied;
```

The warning, printed before runing docker system prune was missing any filter
that was set in the configuration file. In addition, the warning prefixes the
filters with `label=`, which is no longer accurate, now that the prune command
also supports "until" as a filter.
Before this change, only the filters set on the command-line were shown,
and any filter set in the configuration file was missing;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:

With this patch applied, both options from the commandline and options set
in the configuration file are shown;
```

This happens on Windows when dialing a named pipe (a path which is used by CLI
plugins), in that case some debugging shows:
DEBU[0000] conn is a *winio.win32MessageBytePipe
DEBU[0000] conn is a halfReadCloser: false
DEBU[0000] conn is a halfWriteCloser: true
the raw stream connection does not implement halfCloser
In such cases we can simply wrap with a nop function since closing for read
isn't too critical.
Signed-off-by: Ian Campbell <ijc@docker.com>
The `conn` here is `*winio.win32MessageBytePipe` which does not have a
`CloseRead` method (it does have `CloseWrite`) resulting in:

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.

Fairly straight forward. It became necessary to wrap `Plugin.Err` with a type
which implements `encoding.MarshalText` in order to have that field rendered
properly in the `docker info -f '{{json}}'` output.
Since I changed the type somewhat I also added a unit test for `formatInfo`.

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
"common" code, that way, the formatter package stays small
- 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,
not all formatter implementations.

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
