[GitLab CE Docker image] [Documentation] Setting ssh port to a custom port in docker run/compose needs some slight changes

Reference Links:

• https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/docker/README.md#expose-gitlab-on-different-ports
• https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/docker/README.md#install-gitlab-using-docker-compose

Docker compose file I use while starting the image via docker-compose up -d

web:
  image: 'gitlab/gitlab-ce:latest'
  restart: always
  hostname: 'myhostname.com'
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'https://myhostname.com:30443'
      gitlab_rails['gitlab_shell_ssh_port'] = 30022
  ports:
    - '30443:30443'
    - '30022:30022'
  volumes:
    - '/Users/pandel/personal/local_gitlab_data/config:/etc/gitlab'
    - '/Users/pandel/personal/local_gitlab_data/logs:/var/log/gitlab'
    - '/Users/pandel/personal/local_gitlab_data/data:/var/opt/gitlab'

The documentation says that if we want gitlab to be exposed via ports which are not standard, then the above docker compose file should be used. But internally the sshd server still listens to port 22 which is not exposed to the host network.

$:git clone ssh://git@myhostname.com:30022/pandel/testing.git
Cloning into 'testing'...
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
$:nc myhostname.com 30022
$:

Inside container

root@gitlab:/# lsof -i -n
COMMAND PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sshd     25 root    3u  IPv4  49977      0t0  TCP *:22 (LISTEN)
sshd     25 root    4u  IPv6  49978      0t0  TCP *:22 (LISTEN)
nginx   458 root    7u  IPv4  63552      0t0  TCP *:30443 (LISTEN)
nginx   458 root    8u  IPv4  63553      0t0  TCP *:8060 (LISTEN)

I had to solve this by changing the docker compose file port configuration to

...
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'https://myhostname.com:30443'
      gitlab_rails['gitlab_shell_ssh_port'] = 30022
  ports:
    - '30443:30443'
    - '30022:22'
...

This ensured that the website still mentions the git clone link as ssh://git@myhostname.com:30022/pandel/testing.gitand the git clone too starts working normally.

My question is, am I doing something wrong here or does the documentation needs fixing ?
