When you use a tar ball, or a tar,gz file to an image with ADD, it uncompress and untars them, which is great. For a project I am doing right now, there is only a zip file available, and currenlty, Docker just copies the file and does noing with it. Now I know:
unzip thing.zip && tar cfz thing.tar.gz .
(or something like that) is your friend, but my question is: Can you add support for zips to Docker
