What are the best practices (if any) for coupling a docker image registry with a SCM service (such as bitbucket)?

I know a docker registry can live in artifactory, but how can I assure that the two are as tightly coupled as possible?

For example I am worried that without due-diligence from developers the latest Docker image in the registry will not reflect the current state of the Dockerfile in SCM or vice-versa.

For example I am worried that without due-diligence from developers the latest Docker image in the registry will not reflect the current state of the Dockerfile in SCM or vice-versa. Also it is imperative that we can always trace back to the base Dockerfile (that we made) for any image in the registry.

Does anyone know of a locally hostable web front end to my docker registry that is as close as possible to hub.docker.com?

I am currently using konradkleine/docker-registry-frontend:v2 which is great, but we need something closer to hub.docker.com since we are all very used to hub.docker.com at my organization.
