Description of issue

When installing the docker cask, cli-plugins are symlink'd into ~/.docker/cli-plugins. While this is supposed to be the intended location for plugins to be installed, an installation like this is left broken and semi-functional (that is, plugins like buildx, compose, etc. don't work).

Per this issue docker/for-mac#6928 (comment), I was able to get Docker (installed via brew) working and usable, by linking /usr/local/lib/docker/cli-plugins -> /Applications/Docker.app/Contents/Resources/cli-plugins.

I'm opening this here because I'm not certain if this is widespread and if it should be a patch made by brew until upstream resolves it.

For clarity, Docker does not fail to install, rather it fails to install with full functionality of Docker Desktop.

Having this issue as well, maybe .docker folder needs to exist beforehand? On a different Mac I don't recall having this issue

I think my issue, actually, was that I set $DOCKER_CONFIG to ~/.config/docker, but Homebrew didn't install the cli-plugins there, instead it installed to ~/.docker. I ended up switching to colima though since Docker Desktop was turning out to be more hassle than I wanted to deal with. 😅
