I am running docker and I want bash
command completion for docker
commands and parameters.
The auto completion of docker needed not only for mac, its also needed for ubuntu / bash terminals.
In Ubuntu
curl -ksSL https://raw.githubusercontent.com/docker/cli/master/contrib/completion/bash/docker |sudo tee /etc/bash_completion.d/docker
Completion will be available upon next login.
Since its top result in google I added answer here.
