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
to decrypt the private key, and store it un-encrypted to continue using it.

The DefaultStopSignal const has been deprecated, because the daemon already

Docker Engine v20.10 and up includes optimizations to verify if images in the
local image cache need updating before pulling, preventing the Docker Engine
from making unnecessary API requests. These optimizations require the container
image registry to conform to the Open Container Initiative Distribution Specification
(https://github.com/opencontainers/distribution-spec).
While most registries conform to the specification, we encountered some registries
to be non-compliant, resulting in `docker pull` to fail.
As a temporary solution, Docker Engine v20.10 includes a fallback mechanism to
allow `docker pull` to be functional when using a non-compliant registry. A
warning message is printed in this situation:
WARNING Failed to pull manifest by the resolved digest. This registry does not
appear to conform to the distribution registry specification; falling back to
pull by tag. This fallback is DEPRECATED, and will be removed in a future
release.
The fallback is added to allow users to either migrate their images to a compliant
registry, or for these registries to become compliant.
Note that this fallback only addresses failures on `docker pull`. Other commands,
such as `docker stack deploy`, or pulling images with `containerd` will continue
to fail.
Given that other functionality is still broken with these registries, we consider
this fallback a _temporary_ solution, and will remove the fallback in an upcoming
major release.

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.

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.

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

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`

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.

The `aufs` storage driver is deprecated in favor of `overlay2`, and will
be removed in a future release. Users of the `aufs` storage driver are
recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver.
The `aufs` storage driver facilitates running Docker on distros that have no
support for OverlayFS, such as Ubuntu 14.04 LTS, which originally shipped with
a 3.14 kernel.
Now that Ubuntu 14.04 is no longer a supported distro for Docker, and `overlay2`
is available to all supported distros (as they are either on kernel 4.x, or have
support for multiple lowerdirs backported), there is no reason to continue
maintenance of the `aufs` storage driver.

This is a bit manual (as the unit test attests) so we may find we want to add

preserve the information through round-trips.

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.

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).

log-opts are passed to logging-drivers as-is, so the daemon is not
aware what value-type each option takes.
For this reason, all options must be provided as a string, even if
they are used as numeric values by the logging driver.
For example, to pass the "max-file" option to the default (json-file)
logging driver, this value has to be passed as a string;
```json
{
"log-driver": "json-file",
"log-opts": {
"max-size": "10m",
"max-file": "3"
}
}
```
When passed as a _number_ (`"max-file": 3`), the daemon will invalidate
the configuration file, and fail to start;
unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal number into Go value of type string
This patch adds an example to the daemon.json to show these values
have to be passed as strings.

The `overlay` storage driver is deprecated in favor of the `overlay2` storage
driver, which has all the benefits of `overlay`, without its limitations (excessive
inode consumption). The legacy `overlay` storage driver will be removed in a future
release. Users of the `overlay` storage driver should migrate to the `overlay2`
storage driver.
The legacy `overlay` storage driver allowed using overlayFS-backed filesystems
on pre 4.x kernels. Now that all supported distributions are able to run `overlay2`
(as they are either on kernel 4.x, or have support for multiple lowerdirs
backported), there is no reason to keep maintaining the `overlay` storage driver.

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
