Via the documentation for the image and the Dockerfile used to create
it, which should be linked. For example ->
https://hub.docker.com/r/gitlab/gitlab-ce/

Users wanting to run gitlab in a container get it from here. It doesn't
advertise what the base is, but anyone curious can simply click the
'Dockerfile' tab on the page to see.
