Maybe the nginx configuration of Andrioshe also work, but I did some change and mix up with other configurations while trying. I think a configuration file for normal docker-regsitry will also work... will try it in future.

But the more important thing is the gitlab omnibus configuration.

registry_external_url 'https://sub.domain.tld'
registry['registry_http_addr'] = ":"
registry_nginx['enable'] = false
registry['enable'] = true

It is important to set the 'regsitry_http_addr' to the gitlab docker registry ip and port instead of localhost.
