No ssh access to gitlab container, because port 22 is not exposed

Hello,

gitlab provides two ways to access git repositories: http(s) and ssh.
For the "local" gitlab container none of the requiered ports (80, 22) of the container is reachable.
For port 80, this is fixed in pull request #3 .
But I found no way to get ssh working.

Greetings
