This job still runs on gallium. It's also quite slow. Switching it to labs and running it on Trusty with HHVM will speed it up quite significantly as well.
We'll need a way to publish to integration.wikimedia.org in addition to the current doc.wikimedia.org publisher. I don't think we'd need a new publishing tunnel, we can amend the existing one with slightly larger path abstraction to allow hitting either doc.wikimedia.org/:project/:version or integration.wikimedia.org/cover/:project.
