On Docker CLI versions before v28.0.0, using an unknown flag would print
the usage output, showing all available top-level flags and commands;
docker --badopt
unknown flag: --badopt
See 'docker --help'.
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/root/.docker")
...
This output did not include plugin-commands, making the usage output
incomplete. That issue was fixed in [cli@40a6cf7], which loaded all
available cli-plugins, so that a stub was created for printing the
plugin commands in the usage output. Similarly, [cli@79a75da] added
code to hide experimental commands and commands not supported by the
daemon.
However, since 28.0.0 (commit [cli@f28fc7f]), the usage output was
removed for this error, so loading plugins is no longer needed;
docker --badopt
unknown flag: --badopt
Usage: docker [OPTIONS] COMMAND [ARG...]
Run 'docker --help' for more information
This patch removes the code added in [cli@40a6cf7] and [cli@79a75da].
With this patch, the output is still the same;
docker --unknown-flag buildx ls --no-such
unknown flag: --unknown-flag
Usage: docker [OPTIONS] COMMAND [ARG...]
Run 'docker --help' for more information
This function only handles flags defined by the CLI itself; invalid
flags for plugins are handled by the plugin itself, so are not
impacted;
docker buildx ls --no-such
unknown flag: --no-such
Usage: docker buildx ls
Run 'docker buildx ls --help' for more information
