The image Cidan referred to was last pushed 5 hours ago when we released 8.15 and should always be up to date. For more information about our official docker images see https://docs.gitlab.com/omnibus/docker/README.html

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
