You just have to find the complete command and duplicate the line having the alias name instead.

I have alias d-m="docker-machine". In words, d-m shall be the alias for docker-machine.

So on Mac (via brew), the completion files are in cd `brew --prefix`/etc/bash_completion.d/.
For my case I edited the file called docker-machine.
All the way at the bottom there was:

complete -F _docker_machine docker-machine

So I just added another line, with my alias:

complete -F _docker_machine docker-machine
complete -F _docker_machine d-m
