Gitlab Docker "Error executing action `run` on resource 'execute[create gitlab postgresql user]'"

I think the containers are amd64 - see here: Docker so this is most likely why it doesn’t work for you as you are trying to run it on a unsupported processor. I haven’t clicked through all the pages, but even searching for arm or aarch doesn’t show anything.

Maybe this will help though: Docker but I don’t see an EE version for arm from that person, but this search does give some options: Docker

They are not official Gitlab images though, so cannot guarantee their status or validity or security.
