This comment was added in 7929888214
when this code was still in the Moby repository. That comment doesn't appear
to apply to the CLI's usage of this struct though, as nothing in the CLI
sets this field (or uses it), so this should be safe to remove.

I think the cli code block misses a backslash to brevent line break when copy/pasting it to a terminal.
I doubt that this is intentional, if it is, feel free to reject the pr.

Libtrust was only used for pushing schema 2, v1 images, which is no longer
supported; this TODO was likely left from when the CLI and daemon were
in the same repository.

Before this change, the error would suggest installing buildx:
echo "FROM scratch" | DOCKER_BUILDKIT=0 docker build -
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
Install the buildx component to build images with BuildKit:
https://docs.docker.com/go/buildx/
...
However, this error would also be shown if buildx is actually installed,
but disabled through "DOCKER_BUILDKIT=0";
docker buildx version
github.com/docker/buildx v0.9.1 ed00243
With this patch, it reports that it's disabled, and how to fix:
echo "FROM scratch" | DOCKER_BUILDKIT=0 docker build -
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
BuildKit is currently disabled; enabled it by removing the DOCKER_BUILDKIT=0
environment-variable.

Allows us to remove the replace rule, although we probably need to
add it back if we want to update to a newer version from the release
branch (as go mod doesn't support release branches :(( ).

Includes security fixes for net/http (CVE-2022-41717, CVE-2022-41720),
and os (CVE-2022-41720).
These minor releases include 2 security fixes following the security policy:
- os, net/http: avoid escapes from os.DirFS and http.Dir on Windows
The os.DirFS function and http.Dir type provide access to a tree of files
rooted at a given directory. These functions permitted access to Windows
device files under that root. For example, os.DirFS("C:/tmp").Open("COM1")
would open the COM1 device.
Both os.DirFS and http.Dir only provide read-only filesystem access.
In addition, on Windows, an os.DirFS for the directory \(the root of the
current drive) can permit a maliciously crafted path to escape from the
drive and access any path on the system.
The behavior of os.DirFS("") has changed. Previously, an empty root was
treated equivalently to "/", so os.DirFS("").Open("tmp") would open the
path "/tmp". This now returns an error.
This is CVE-2022-41720 and Go issue https://go.dev/issue/56694.
- net/http: limit canonical header cache by bytes, not entries
An attacker can cause excessive memory growth in a Go server accepting
HTTP/2 requests.
HTTP/2 server connections contain a cache of HTTP header keys sent by
the client. While the total number of entries in this cache is capped,
an attacker sending very large keys can cause the server to allocate
approximately 64 MiB per open connection.
This issue is also fixed in golang.org/x/net/http2 vX.Y.Z, for users
manually configuring HTTP/2.
Thanks to Josselin Costanzi for reporting this issue.
This is CVE-2022-41717 and Go issue https://go.dev/issue/56350.

Commit 20ba591b7f fixed incorrect feature
detection in the CLI, but introduced a regression; previously the "ping"
would only be executed if needed (see b39739123b),
but by not inlining the call to `ServerInfo()` would now always be called.
This patch inlines the code again to only execute the "ping" conditionally,
which allows it to be executed lazily (and omitted for commands that don't
require a daemon connection).

When server is unreachable and docker checkpoint (or any command that
needs to check the server type) is run, incorrect error was returned.
When checking if the daemon had the right OS, we compared the OSType
from the clients ServerInfo(). In situations where the client cannot
connect to the daemon, a "stub" Info is used for this, in which we
assume the daemon has experimental enabled, and is running the latest
API version.
However, we cannot fill in the correct OSType, so this field is empty
in this situation.
This patch only compares the OSType if the field is non-empty, otherwise
assumes the platform matches.
before this:
docker -H unix:///no/such/socket.sock checkpoint create test test
docker checkpoint create is only supported on a Docker daemon running on linux, but the Docker daemon is running on
with this patch:
docker -H unix:///no/such/socket.sock checkpoint create test test
Cannot connect to the Docker daemon at unix:///no/such/socket.sock. Is the docker daemon running?

These tests were using the default client, which would try to make a connection
with the daemon (which isn't running). Some of these test subsequently had
tests that depended on the result of that connection (i.e., "ping" result).
This patch updates the test to use a dummy client, so that the ping result is
predictable.

This allows the cli to be initialized with a (custom) API client.
Currently to be used for unit tests, but could be used for other
scenarios.

Use /bin/sh in the examples, as it's more likely to be present in a
container than bash (some users got confused by this, so using plain
"sh" in the examples could lead to less confusion).
Also added some extra wording around defaults, and how they're inherited
by the exec'd process.
It's definitely not "perfect" yet (lots to do in this document to improve
it), but it's a start :)

Update the example output to not use deprecated storage drivers or
Windows versions.
Also removes the section about `--debug`, because the `docker info` output
depends on the _daemon_ (not the client) to have debug mode enabled.

Some touch-ups in the attach reference and man-page;
- remove uses of old images (ubuntu 14.04)
- adds some more wording about `-i` and `-t` to use the detach sequence.
- use `--filter` instead of `grep` to list the container, to make the
example more portable.
