Zsh

1. Place the completion script in your /path/to/zsh/completion (typically ~/.zsh/completion/):
   
   下载自动完成文件

mkdir -p ~/.zsh/completion

curl -L https://raw.githubusercontent.com/docker/compose/1.21.0/contrib/completion/zsh/_docker-compose > ~/.zsh/completion/_docker-compose

1. Include the directory in your $fpath by adding in ~/.zshrc:
   
   在~/.zshrc中加入

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

1. Make sure compinit is loaded or do it by adding in ~/.zshrc:
   
   确保已经加载compinit，或加入到~/.zshrc

autoload -Uz compinit && compinit -i

1. Then reload your shell:
   
   重新载入Shell

exec $SHELL -l

Available completions

Depending on what you typed on the command line so far, it completes:

• available docker-compose commands
• options that are available for a particular command
• service names that make sense in a given context, such as services with running or - stopped instances or services based on images vs. services based on Dockerfiles. For docker-compose scale, completed service names automatically have “=” appended.
• arguments for selected options. For example, docker-compose kill -s completes some signals like SIGHUP and SIGUSR1.
