Docker Command-line Auto-completion 命令自动补全

Make sure you have installed oh-my-zsh on your computer.

WITH OH-MY-ZSH SHELL

Add docker and docker-compose to the plugins list in ~/.zshrc to run autocompletion within the oh-my-zsh shell. In the following example, ... represent other Zsh plugins you may have installed.

plugins=(
  ... 
  docker 
  docker-compose
)

WITHOUT OH-MY-ZSH SHELL

Place the completion script in your
 /path/to/zsh/completion (typically ~/.zsh/completion/):

mkdir -p ~/.zsh/completion 

curl -L https://raw.githubusercontent.com/docker/compose/1.25.0/contrib/completion/zsh/_docker-compose > ~/.zsh/completion/_docker-compose 

curl -L https://raw.githubusercontent.com/docker/docker/master/contrib/completion/zsh/_docker > ~/.zsh/completion/_docker

Include the directory in your $fpath by adding in ~/.zshrc:

fpath=(~/.zsh/completion $fpath) 

Make sure compinit is loaded or do it by adding in ~/.zshrc:

 autoload -Uz compinit && compinit -i

Then reload your shell:

exec $SHELL -l

Issues

I add docker in .zshrc. plugins=(git docker) and restart my Terminal, but [TAB][TAB] is not working.
