Please upload working Docker image to Dockerhub

[tripleee]

It would be convenient and robust as well as good for reducing resource consumption if a working generated Docker image could be uploaded to https://dockerhub.com/ so that we could simply docker pull visualphoenix/jdsl rather than have to build the image ourselves (and besides, it would shield many of us from build failures).

(I'm guessing https://hub.docker.com/u/visualphoenix is you?)
