Hi, I think it's good to have official docker image of karaf. There are some images in hub.docker.com, but mostly without documentation. I prepared proposal how official image should looks like. It runs as non-root user karaf and add way how to use it in development phase (map host maven repository to container). Let me know what you think about it.
