unable to git through ssh using docker gitlab

I looked the different posts concerning gitlab, docker, and ssh issues without any help. So, I ask my question here.

I have the following setting:

• linux box with ubuntu server 14.04 and IP 192.168.1.104

• DNS: git.mydomain.com = 192.168.1.104

• A gitlab docker that I start, according to the official doc, this way:

   sudo docker run --detach --name gitlab_app --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data gitlab_image

  or

   sudo docker run --detach --name gitlab_app --publish 8080:80 --publish 2222:22 -e "GITLAB_SHELL_SSH_PORT=2222" --volumes-from gitlab_data gitlab_image

• the linux box runs an nginx which redirects (proxy_pass) git.mydomain.com to 192.168.1.104:8080

• I access git.mydomain.com without any issue, everything works.

• I generated an ssh key that I have added to my profile on gitlab and added the following lines to my ~/.ssh/config

   Host git.mydomain.com
   User git
   Port 2222
   IdentityFile /home/user/.ssh/id_rsa

• If I try

   ssh -p 2222 git@git.mydomain.com

  the connection is closed. I assume it is because only a git-shell is permitted.

• But, if I try

   mkdir test
   cd test
   git init
   touch README.md
   git add README.md
   git commit -m "first commit"
   git remote add origin git@git.domain.com:user/test.git
   git push -u origin master

  it stucks with

   Connection closed by 192.168.1.104
   fatal: Could not read from remote repository.
  
   Please make sure you have the correct access rights
   and the repository exists.

I also tried with

    git remote add origin git@git.domain.com:2222/user/

and the result was the same. Note that the logs of gitlab docker include

   [2015-03-06T11:04:43+00:00] INFO: group[git] created
   [2015-03-06T11:04:43+00:00] INFO: user[git] created
   [2015-03-06T11:04:44+00:00] INFO: group[gitlab-www] created
   [2015-03-06T11:04:44+00:00] INFO: user[gitlab-www] created

Any idea how I can fix this issue?

Also, it seems that the "GITLAB_SHELL_SSH_PORT=2222" option used when starting gitlab docker should result in the port appearing in the git urls displayed but gitlab but it's not the case.

Thanks in advance for your help

Can you check the content, permissions, and owner of /var/opt/gitlab/.ssh/authorized_keys? You will have to attach to container (e.g. sudo docker exec -it gitlab_app bash). I'm wondering if it's a permission issue where root owns this file but user git is unable to read/write to it.

Thanks for your answer. I fixed the issue by replacing the docker I have installed with apt-get by the one suggested in docker's documentation, which is more recent.

Yes, I've found that Docker v1.5.0 works far better than v1.1, which is available by apt-get, although I don't know why it would solve this particular issue. Looks like we can close this issue now?

Status changed to closed

Yes, you're right, we can close it. Thanks for the help.
