Removal: Support for external container registries in GitLab
Removal Summary
GitLab supports, using an external container registry with GitLab as an auth endpoint.
We've been able to support that because, until recently, GitLab's fork of Docker Distribution was compatible with the upstream version. However, that is no longer the case.
In recent months, GitLab has updated the GitLab Container Registry with scalability, performance, and UX improvements that are no longer compatible with the upstream Docker Distribution.
So, we are announcing the deprecation of this feature and will plan the associate removal, #376217 (closed), for GitLab 16.0.
Required changes
Update the docs to make it very clear that we no longer provide support for third-party registry compatibility. Use an external container registry with GitLab as an auth endpoint is the most prominent section.
