I see containers as one ingredient in a more automated and tested pipeline from development through CI to production. mediawiki-containers could expand to cover the development use case, but I think we can and should move from there into CI, and finally production.
Right now, Yuvi is evaluating the Kubernetes cluster manager in labs. Its features include scheduling of "pods" (groups of containers) to hardware nodes, networking, rolling deploys and more. While all these features provide a very high degree of automation, they also mean that failures in Kubernetes can have grave consequences. I think operations are wise to wait for Kubernetes to mature a bit further before considering it for critical production use cases. Rather than waiting until one-stop cluster managers are mature, we could also start with a more traditional config / deploy system. I have played with this approach using Ansible [1] a while ago, and the ergonomics are pretty much the same as git-based deploys. There is also some support to run docker images in systemd, which could be an alternative if we want to avoid the dependency on the docker runtime in production. This older task lists some options: https://phabricator.wikimedia.org/T93439 Lets get together and figure out a plan.
