Hi, I added an initial version of a Dockerfile for the Sling Launchpad - you can find it under http://svn.apache.org/repos/asf/sling/trunk/launchpad/docker/ . In my limited tests it works as expected, but since I'm not a Docker expert I probably missed some things.
It would be great if anyone with more knowledge would take a look. I plan to use it to build an 'official' docker image for the Launchpad 8 release which would be pushed on Docker Hub. Thanks, Robert
