GitLab docker registry reject push with error 500

  • 772

Summary

I have self-hosted gitlab, installed with apt. I don't have git_data_dir in default location (see config). I can't push docker image into docker registry, directory <shared_path>/registry does not exists. No migrations, no backup/restore procedure, last version.

Problem to solve

GitLab reject Docker image push from remote location with error 500. I'm not able to push image into my private docker registry. Have anyone idea why and how to solve it?

Biggest problem (if I understand it right) is:

filesystem: open /mnt/data/git-data/gitlab-rails/shared/registry/docker/registry/v2/repositories/testing/registry/_layers/sha256/c9b1b535fdd91a9855fb7f82348177e5f019329a58c53c47272962dd60f71fc9/link: permission denied

  1. Who is the owner of your registry directory?

    Try changing the owner to "registry". I had a similar problem and changed the owner of "/var/opt/gitlab/gitlab-rails/shared/registry/docker/registry/" from "git" to "registry"
