I have a machine with ssh running on it. Now, I wanted to run the gitlab inside the docker container. So, followed the instructions mentioned here https://docs.gitlab.com/omnibus/docker/. The instruction says bind the container ssh port 22 with host machine's ssh port(22). I was unable to do this because port was already binded with openssh server in the host machine. So I binded the container's ssh port to some other port say 222 or so. Doing so gitlab got set-up but when I try to clone the project using ssh way I am not able to do.
Is there a way to fix this issue? what could be reason, I suspect it's because of the port mapping. I want to have the ssh running on my host machine, run the gitlab inside the container and should be able to use ssh way for code commit,clone and push.
Docker port mapping is one thing but you also need to adapt the gitlab rails configuration in gitlab.rb to specify the custom ssh port :
gitlab_rails['gitlab_shell_ssh_port'] = 222
and restart the container
