GitLab container registry
The GitLab Runner is be able to build a container image
It will also soon be able to upload build artifacts.
If it uploads a container image we should make that available via the docker image interface so that you can use GitLab as a private container registry, an alternative to Docker Trusted Registry.
Instead of using the upload build artifacts function it might be easier to use native Docker upload functionality docker push my-registry:5000/my-image.
