Commit 3991faf464 moved search into the registry
package, which also made the `dockerversion` package a dependency for registry,
which brings additional (indirect) dependencies, such as `pkg/parsers/kernel`,
and `golang.org/x/sys/windows/registry`.
Client code, such as used in docker/cli may depend on the `registry` package,
but should not depend on those additional dependencies.
This patch moves setting the userAgent to the API router, and instead of
passing it as a separate argument, includes it into the "headers".
As these headers now not only contain the `X-Meta-...` headers, the variables
were renamed accordingly.

Commit e7d75c8db7 fixed validation of "host"
mode values, but also introduced a regression for validating "container:"
mode PID-modes.
PID-mode implemented a stricter validation than the other options and, unlike
the other options, did not accept an empty container name/ID. This feature was
originally implemented in fb43ef649b, added some
some integration tests (but no coverage for this case), and the related changes
in the API types did not have unit-tests.
While a later change (d4aec5f0a6) added a test
for the `--pid=container:` (empty name) case, that test was later migrated to
the CLI repository, as it covered parsing the flag (and validating the result).

commit 1bd486666b refactored this code, but
it looks like I removed some changes in this part of the code when extracting
these changes from a branch I was working on, and the behavior did not match
the function's description (name to be empty if there is no "container:" prefix
Unfortunately, there was no test coverage for this in this repository, so we
didn't catch this.
This patch:
- fixes containerID() to not return a name/ID if no container: prefix is present
- adds test-coverage for TestCgroupSpec
- adds test-coverage for NetworkMode.ConnectedContainer
- updates some test-tables to remove duplicates, defaults, and use similar cases

Make if more explicit which test-cases should be valid, and make it the
first field, because the "valid" field is shared among all test-cases in
the test-table, and making it the first field makes it slightly easier
to distinguish valid from invalid cases.

Commit 3246db3755 added handling for removing
cluster volumes, but in some conditions, this resulted in errors not being
returned if the volume was in use;
docker swarm init
docker volume create foo
docker create -v foo:/foo busybox top
docker volume rm foo
This patch changes the logic for ignoring "local" volume errors if swarm
is enabled (and cluster volumes supported).
While working on this fix, I also discovered that Cluster.RemoveVolume()
did not handle the "force" option correctly; while swarm correctly handled
these, the cluster backend performs a lookup of the volume first (to obtain
its ID), which would fail if the volume didn't exist.

SearchRegistryForImages does not make sense as part of the image
service interface. The implementation just wraps the search API of the
registry service to filter the results client-side. It has nothing to do
with local image storage, and the implementation of search does not need
to change when changing which backend (graph driver vs. containerd
snapshotter) is used for local image storage.
Filtering of the search results is an implementation detail: the
consumer of the results does not care which actor does the filtering so
long as the results are filtered as requested. Move filtering into the
exported API of the registry service to hide the implementation details.
Only one thing---the registry service implementation---would need to
change in order to support server-side filtering of search results if
Docker Hub or other registry servers were to add support for it to their
APIs.
Use a fake registry server in the search unit tests to avoid having to
mock out the registry API client.

It's surprising that the method to begin serving requests is named Wait.
And it is unidiomatic: it is a synchronous call, but it sends its return
value to the channel passed in as an argument instead of just returning
the value. And ultimately it is just a trivial wrapper around serveAPI.
Export the ServeAPI method instead so callers can decide how to call and
synchronize around it.
Call ServeAPI synchronously on the main goroutine in cmd/dockerd. The
goroutine and channel which the Wait() API demanded are superfluous
after all. The notifyReady() call was always concurrent and asynchronous
with respect to serving the API (its implementation spawns a goroutine)
so it makes no difference whether it is called before ServeAPI() or
after `go ServeAPI()`.

The Server.cfg field is never referenced by any code in package
"./api/server". "./api/server".Config struct values are used by
DaemonCli code, but only to pass around configuration copied out of the
daemon config within the "./cmd/dockerd" package. Delete the
"./api/server".Config struct definition and refactor the "./cmd/dockerd"
package to pull configuration directly from cli.Config.

Kubernetes only permits RuntimeClass values which are valid lowercase
RFC 1123 labels, which disallows the period character. This prevents
cri-dockerd from being able to support configuring alternative shimv2
runtimes for a pod as shimv2 runtime names must contain at least one
period character. Add support for configuring named shimv2 runtimes in
daemon.json so that runtime names can be aliased to
Kubernetes-compatible names.
Allow options to be set on shimv2 runtimes in daemon.json.
The names of the new daemon runtime config fields have been selected to
correspond with the equivalent field names in cri-containerd's
configuration so that users can more easily follow documentation from
the runtime vendor written for cri-containerd and apply it to
daemon.json.

The errors are already returned to the client in the API response, so
logging them to the daemon log is redundant. Log the errors at level
Debug so as not to pollute the end-users' daemon logs with noise.
Refactor the logs to use structured fields. Add the request context to
the log entry so that logrus hooks could annotate the log entries with
contextual information about the API request in the hypothetical future.

This is a squashed version of various PRs (or related code-changes)
to implement image inspect with the containerd-integration;
- add support for image inspect
- introduce GetImageOpts to manage image inspect data in backend
- GetImage to return image tags with details
- list images matching digest to discover all tags
- Add ExposedPorts and Volumes to the image returned
- Refactor resolving/getting images
- Return the image ID on inspect
- consider digest and ignore tag when both are set
- docker run --platform

The IPCMode type was added in 497fc8876e, and from
that patch, the intent was to allow `host` (without `:`), `""` (empty, default)
or `container:<container ID>`, but the `Valid()` function seems to be too relaxed
and accepting both `:`, as well as `host:<anything>`. No unit-tests were added
in that patch, and integration-tests only tested for valid values.
Later on, `PidMode`, and `UTSMode` were added in 23feaaa240
and f2e5207fc9, both of which were implemented as
a straight copy of the `IPCMode` implementation, copying the same bug.
Finally, commit d4aec5f0a6 implemented unit-tests
for these types, but testing for the wrong behavior of the implementation.
This patch updates the validation to correctly invalidate `host[:<anything>]`
and empty (`:`) types.
