Hi, There is no dockerfile for vgate3_vanilia because i did not find a way to solve it with dockerfile. The recipe is this: - fire up a virtualbox VM - attach the vgate.vdi from the opengatecollaboration - boot from a recovery cd, like R.I.P. or anything similar - mount the vgate (optional: - chroot to vgate, and clean the apt cache with: apt-get clean) - create a tar.gz from the vgate root -export the tar.gz from the VM (shared directory, scp, anyhow) - create a docker image from the tar.gz (see docker import) - tag the docker image and upload it After that you have a trustable base image, and you can modify it like i did. On long term OpengateCollaboration could publish official images, and that way you don't have to choose between trustable source and convenience. Another option to build Gate inside docker. This is definitely possible, and yields much smaller final image (e.g. you do not need the whole ubuntu desktop), but I did not do this because of two main reasons: - I was lazy - That way you have the exact same binaries like you would have in the virtualbox. (you can directly compare speed, bugs should be the same, more people test it, etc) (If you want to check the vanilia edition, you can compare the md5 hashes of the files.) Anyway, I am really happy that somebody tried it and it works. Now I am on holiday for a month, so I will not be able to do any sophisticated test or benchmark but it would be nice to see how it works in practice. So, if anybody has good or bad experience, then please share it.
