GitLab is the other large open source Rails project. We choose to package below the container level with Omnibus packages. These run without all the Docker dependencies and install in 2 minutes. We did this because many of our users could not run a recent/custom kernel with Docker. We're very happy with the choice and are able to run the Omnibus packages on top of our images https://gitlab.com/gitlab-org/gitlab-ce/tree/master/docker https://gitlab.com/gitlab-org/gitlab-ce/tree/master/docker That being said, it is still a bit silly how hard a Rails app is to install.
