I was under the impression that everyone used the fully featured official docker image (https://hub.docker.com/r/gitlab/gitlab-ee/). We've been using this for over a year without issues now. Is there a reason you need the unofficial version? Does it do something different?
I've added a section to say that these images are officially supported with https://gitlab.com/gitlab-org/omnibus-gitlab/commit/26501d91...
If you experience problems with them please feel free to file an issue under https://gitlab.com/gitlab-org/omnibus-gitlab/issues (more than 1500 have been closed there already).
I suspect that many of the upgrade problems you experienced can be solved by using an official image.
I agree that the demo video we show is limited to a specific Kubernetes installation (OpenShift self hosted). In 2017 we plan to make sure everyone can use it, for details see https://gitlab.com/gitlab-org/gitlab-ce/issues/25986
OK. I definitely remember running in to something that looked official but wasn't up to date (remotely) a few weeks ago. Perhaps it was this image, perhaps not. IIRC at the time I was judging only from the 'updated [time periods] ago' data in the docker hub webpages.
Anyway, if there is an urgent problem with those consider tweeting to @gitlabstatus to get our attention. I think it won't be needed since many people use them so we should be on top of them. The only package that is sometimes late is the non-docker package for the Raspberry Pi since it takes hours to build.
