As it's just an alias for filepath.IsAbs. Also added a normalize step in
TrimBuildFilesFromExcludes, so that callers are not _required_ to first
normalize the path.
We are considering deprecating and/or removing this function in the archive

`NewDockerCli` was configuring the standard streams using local code; this patch
instead uses the available `WithStandardStreams()` option to do the same.
There is slight difference in the order of events;
Previously, user-provided options would be applied first, after which NewDockerCli
would check if any of "in", "out", or "err" were nil, and if so set them to the
default stream (or writer) for that output.
The new code unconditionally sets the defaults _before_ applying user-provided
options. In practive, howver, this makes no difference; the fields set are not
exported, and the only functions updating them are `WithStandardStreams`,
`WithInputStream`, and `WithCombinedStream`, neither of which checks the old
value (so always overrides).

Avoid updating the config-file if nothing changed. This also prevents creating
the file and config-directory if the default is used and no config-file existed
yet.
`config.Save()` performs various steps (creating the directory, updating

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.

The default output for Cobra aliases only shows the subcommand as alias, which
is not very intuitive. This patch changes the output to print the full command
as it would be called by the user.
Note that there's still some improvements to be made; due to how aliases must be
set-up in Cobra, aliases at different "levels" are still not shown. So for example,
`docker ps --help` will not show `docker container ps` as alias, and vice-versa.
This will require additional changes, and can possibly be resolved using custom
metadata/annotations.

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

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

The `~/.dockercfg` file was replaced by `~/.docker/config.json` in 2015
(github.com/docker/docker/commit/18c9b6c6455f116ae59cde8544413b3d7d294a5e),
but the CLI still falls back to checking if this file exists if no current
(`~/.docker/config.json`) file was found.
Given that no version of the CLI since Docker v1.7.0 has created this file,
and if such a file exists, it means someone hasn't re-authenticated for
5 years, it's probably safe to remove this fallback.

Remove "Docker" from registry, as the registry specification is no
longer docker-specific, but part of the OCI distribution spec.
Also removed "Register" from one of the docs pages, as the login
command hasn't supported creating a new acccount on Docker Hub for
a long time.
I'm wondering if we should be more explicit about what log in / out
does (effectively; authenticate, and on success store the credentials
or token, and on log out; remove credentials/token).

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.

Previously, `version: "3"` was equivalent to `version: "3.0"`, which
caused confusion for many users, as they expected it to be "3.x".
docker-compose and docker compose (v2) have adopted the compose-spec
(https://compose-spec.io), which no longer has a version field in
the compose file, and always picks the "latest" supported version.
This changes how `docker stack` interprets "major" version numbers
specified in compose-files:
When only the major version ("3") is specified, it is now equivalent
to "3.x" (latest supported v3 schema).
Compose-files that specify both major and minor version (e.g. "3.0"
or "3.1") continue to use the existing behavior; validation is down-
graded to the specified version and will produce an error if options
are used that are not supported in that schema version. This allows
users to locally verify that a composse-file does not use options
that are not supported in the intended deployment environment (for
example if the deploy environment only supports older versions of
the schema).

The compose spec (https://compose-spec.io) defines the version to be optional,
and implementations of the spec to check for supported attributes instead.
While this change does not switch the `docker stack` implementation to use the
compose-spec, it makes it function more similar. Previously, omitting a version
number would either produce an error (as the field was required), or switched
the handling to assume it was version 1.0 (which is deprecated).
With this change, compose files without a version number will be handled as
the latest version supported by `docker stack` (currently 3.10). This allows
users that work with docker-compose or docker compose (v2) to deploy their
compose file, without having to re-add a version number. Fields that are
not supported by stackes (schema 3.10) will still produce an error.

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 [==================================================>]

3. Once the service starts failing, automatic rollback is started; progress-bars now move in the reverse direction;

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

----------------------------------------
Progress bars always go from left to right; also in a rollback situation;
After updating to the "faulty" entrypoint, task are deployed:

Relates to the deprecation, added in 3c0a167ed5
The docker CLI up until v1.7.0 used the `~/.dockercfg` file to store credentials
after authenticating to a registry (`docker login`). Docker v1.7.0 replaced this
file with a new CLI configuration file, located in `~/.docker/config.json`. When
implementing the new configuration file, the old file (and file-format) was kept
as a fall-back, to assist existing users with migrating to the new file.
Given that the old file format encourages insecure storage of credentials
(credentials are stored unencrypted), and that no version of the CLI since
Docker v1.7.0 has created this file, the file is marked deprecated, and support
for this file will be removed in a future release.
This patch adds a deprecation warning, which is printed if the CLI falls back
to using the deprecated ~/.dockercfg file.

We refactorted `ForwardAllSignals` so it blocks but did not update the

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;

_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 c2626a8270 replaced the use of
github.com/docker/docker/pkg/homedir with Golang's os.UserHomeDir().
This change was partially reverted in 7a279af43d
to account for situations where `$HOME` is not set.
In situations where no configuration file is present in `~/.config/`, the CLI
falls back to looking for the (deprecated) `~/.dockercfg` configuration file,
which was still using `os.UserHomeDir()`, which produces an error/warning if
`$HOME` is not set.
This patch introduces a helper function and a global variable to get the user's
home-directory. The global variable is used to prevent repeatedly looking up
the user's information (which, depending on the setup can be a costly operation).

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.

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 |

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 ..
# drwxr-xr-x 2 sebastiaan staff 64 Aug 14 14:15 some-directory
This patch updates the `docker rm` / `docker container rm` command to not produce
an error when attempting to remove a missing containers, and instead only print
the error, but return a zero (0) exit code.
With this patch applied:
docker create --name mycontainer busybox \
&& docker rm nosuchcontainer mycontainer; \
echo exit code: $?; \
docker ps -a --filter name=mycontainer
# df23cc8573f00e97d6e948b48d9ea7d75ce3b4faaab4fe1d3458d3bfa451f39d

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.
Before this change:
-----------------------------
Create a service with two env-vars
```bash
docker service create --env FOO=bar --env BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"FOO=bar",
"BAR=baz"
]
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --env-rm FOO --env-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Env }}' test | jq .
[
"BAR=baz"
]
```
Create a service with two labels
```bash
docker service create --label FOO=bar --label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --label-rm FOO --label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.Labels }}' test | jq .
{
"BAR": "baz"
}
```
Create a service with two container labels
```bash
docker service create --container-label FOO=bar --container-label BAR=baz --name=test nginx:alpine
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
"FOO": "bar"
}
```
Update the service, with the intent to replace the value of `FOO` for a new value
```bash
docker service update --container-label-rm FOO --container-label-add FOO=updated-foo test
docker service inspect --format '{{json .Spec.TaskTemplate.ContainerSpec.Labels }}' test | jq .
{
"BAR": "baz",
}
```

When doing `docker service inspect --pretty` on services without
`TaskTemplate.Resources` or `TaskTemplate.Resources.Limits`, the command
fails. This is due to a missing check on ResourceLimitPids().
This bug has been introduced by 395a6d560d
and produces following error message:
```
Template parsing error: template: :139:10: executing "" at <.ResourceLimitPids>: error calling ResourceLimitPids: runtime error: invalid memory address or nil pointer dereference

Both libaries provide similar functionality. We're currently using
Google Shlex in more places, so prefering that one for now, but we
could decide to switch to mattn/go-shellwords in future if that
library is considered better (it looks to be more actively maintained,
but that may be related to it providing "more features").
