My experience is quite different. I am experiencing a 500 error on every push to the container registry in my project, I contacted GitLab support over two weeks ago, and the person has clearly no idea how to debug this (and seems very unfamiliar with GitLab, for example couldn't find the web page for my container registry from my Docker image name, e.g. registry.gitlab.com/my/project -> gitlab.com/my/project/container_registry). Very disappointed.
