docker: gitlab + traefik & port 22

Viewed 5803

I need to set up Gitlb behind Traefik.

Everything works except authentication to the app via command line - I don't know how to expose port 22 via traefik.

Any idea how to set it up? How to expose port 22 of a docker container (via traefik)?

I changed the default port from 22 to 10022.

I'm getting via netstat -tulpn

I don't understand why 10022 is connected to docker-proxy.

When I try:

git push --set-upstream origin master
ssh: connect to host git.myserver.com port 10022: Connection refused
fatal: Could not read from remote repository.

Thank you very much
