Small tweak to the known fix to the vendor completion docker zsh wsl2 issue
Raw
wsl-zsh-docker-compinit.md

The bug

As described in this github discussion the issue arises when you mix several things together

  • windows setup
  • runs wsl / wsl2
  • uses zsh as a shell on wsl
  • installed docker desktop

In these situations you will the 'vendor completion' /usr/share/zsh/vendor-completions/_docker because (supposedly) the docker desktop install replaces it with a phony simlink

The solution

The solution described in this github discussion works, aka running

sudo rm -rf /usr/share/zsh/vendor-completions/_docker

and then

sudo cp /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker /usr/share/zsh/vendor-completions/

does work but only after one extra step

The extra step

Installing Docker Desktop isn't enough to generate the true backend files at the location /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker, you need to enable docker backend first as explained here Only after this step will you be able to run the cp command !

Don't forget

To make them non-writeable as mentionned in the OP :)
