Zsh Docker Plugin not Working
You might want to try and remove any .zcompdump-(...)
files you may have on your user's home directory - using something like rm ~/.zcompdump*
on a terminal, or some file browser - and then reload the .zschrc
file with the command source ~/.zshrc
or restart the terminal - whichever works best for you. See this
Then see if it works.
It seems oh-my-zsh is not loading plugins/docker/_docker
file. You must add it to ~/.zshrc
in an another way.
Add these lines to your ~/.zshrc
file:
fpath+=($ZSH/plugins/docker)
autoload -U compinit && compinit
