A SSH request is made against the host (usually port 22) using the `git` user, e.g. `git clone git@domain:user/repo.git`. 2. In `/home/git/.ssh/authorized_keys` , the command executes the `/app/gitea/gitea` script. 3. `/app/gitea/gitea` forwards the SSH request to port 2222 which is mapped to the SSH port (22) of the container. 4. Due to the existence of the public key of the `git` user in `/home/git/.ssh/authorized_keys` the authentication host → container succeeds and the SSH request get forwarded to Gitea running in the docker container. |
