Restore Gitlab-Data (Docker installation)

Hi all, I am running Gitlab with the original docker image in a Kubernetes Cluster. All was fine, but my Cluster is gone by failure. I do have access to 3 persistent images (all of them built with “tar cvf”):

  • /etc/gitlab
  • /var/opt/gitlab
  • /var/log/gitlab
    I can access all files and therefore “could” copy them onto new hardware in a new gitlab container. Unfortunately after copying and restarting the container it fails to start. So I cannot access the log-files to gain more information.

For copying I used the tar archives. I might be able to build a block device, but no clue this would help in any way.
Any help appreciated: how can I get gitlab running again with my 3 disk-images?

Thanks Wolfram
