The docker plugin worked great when either building local images or images which are intended to be pushed to a user-specified registry (like registry.haufe.io). If you wanted to push to the official docker registry though, this did not work, as it expects you to build images without specifying a registry, and logging in to https://index.docker.io/v1/ instead of e.g. docker.io or (which would make sense) hub.docker.com. The plugin now detects docker.io and hub.docker.com and "does the right thing", i.e.
