首先安装以下公式：

brew install bash-completion
brew cask install docker

接下来通过GUI启动器，找到Docker图标并启动它，然后按照提示。
然后重新启动Bash终端。
现在运行以下命令以创建一些符号链接：

ln -s /Applications/Docker.app/Contents/Resources/etc/docker.bash-completion /usr/local/etc/bash_completion.d/docker
ln -s /Applications/Docker.app/Contents/Resources/etc/docker-machine.bash-completion /usr/local/etc/bash_completion.d/docker-machine
ln -s /Applications/Docker.app/Contents/Resources/etc/docker-compose.bash-completion /usr/local/etc/bash_completion.d/docker-compose

然后重新启动BASH终端。
因此，运行上述LN命令导致正在创建以下文件：

$ pwd
/usr/local/etc/bash_completion.d
$ cd /usr/local/etc/bash_completion.d/
$ ll | grep docker
