CIs can frequently pull many times a day from dockerhub and exhaust the rate limit for unautehnticated users. Especially CI jobs that require images inside their job fall victim to this as the pulled images are discarded after the pipeline completes. I intend to set-up a pull-through cache for the purpose of centrally caching images and reduce unnecessary bandwidth usage towards public registries. A possible alternative solution might be GitLab's dependency proxy. Todo: research about this first
