Installing Command Completion——实现docker命令的自动补全
Docker for Mac comes with scripts to enable completion for the docker, docker-machine, and docker-compose commands. The completion scripts may be found inside Docker.app, in the Contents/Resources/etc/ directory and can be installed both in Bash and Zsh.
Mac的Docker附带了一些脚本，用于支持docker、docker-machine和docker-compose命令的完成。completion脚本可以在Docker.app中找到，在Contents/Resources/etc/目录，可以安装在Bash和Zsh
1）Bash
Bash has built-in support for completion To activate completion for Docker commands, these files need to be copied or symlinked to your bash_completion.d/directory. For example, if you installed bash via Homebrew:
Bash内置了对completion的支持，可以激活Docker命令的完成，需要复制这些文件或将这些文件链接到bash_completion.d/目录。例如，如果你通过Homebrew安装bash:
etc=/Applications/Docker.app/Contents/Resources/etc
ln -s $etc/docker.bash-completion $(brew --prefix)/etc/bash_completion.d/docker
ln -s $etc/docker-machine.bash-completion $(brew --prefix)/etc/bash_completion.d/docker-machine
ln -s $etc/docker-compose.bash-completion $(brew --prefix)/etc/bash_completion.d/docker-compose
