title: Gitlab with Docker won't update
body: <p>I'm currently using Gitlab using Docker. The container is using the latest image for Gitlab, but the admin area shows me a different version. How can I use the latest one ? I don't understand why Gitlab shows me a different version of what I'm using. I tried <code>gitlab-ctl upgrade</code> command, with no effect.</p>
  
  <p>Docker shows me the correct (latest) image </p>

  <p>Administration shows me 11.1.4 (so, I can't benefit 11.4.0 features)</p>

  <p>Am I doing thing wrong ? When updating, I just change the image version. Everything works well since months, but now...</p>
