I’m using com.spotify:docker-maven-plugin (https://github.com/spotify/docker-maven-plugin) in a project other than Hawkular, and I think it works quite well. Yes, it is easier to use if you build an assembly with the layout, and then simply ADD the archive via the Dockerfile. (Recall that ADD will extract the contents of a ZIP or TAR archive, whereas COPY just copies files.) The Maven plugin can easily build the image, register it locally, and optionally push to DockerHub.

The docker images are not created and deployed to a docker registry as
part of the build, it will just create a folder where you can run the
docker build from. None of the maven docker plugins I looked at seemed
to really work properly, so its still a manual process to do the build
(and push to a registry). Its something which needs to be improved.
