How to add bash command completion for Docker on Mac OS X?

Question

I am running docker and I want bash command completion for docker commands and parameters.

Answer 1

The completion scripts come with Docker Beta. I want them to stay up to date. So, on OS X...

• Install homebrew's bash-completion

• Symlink the files

  find /Applications/Docker.app \
  -type f -name "*.bash-completion" \
  -exec ln -s "{}" "$(brew --prefix)/etc/bash_completion.d/" \;
