Finally, this should re-pull the image from cache, which is not working in my case, rather pulling from docker hub instead. $ time docker pull ...

According to the docs, "The caching semantics of the underlying image provider make this policy efficient. The pull attempt is fast because all image layers are cached." But this doesn't seem to be the case at all. The image is stored on the remote GitLab Registry, and if I manually docker-pull a fresh build on my own PC, it takes ~60 seconds ...

Every build starts from zero which can be slow and wasteful.
