Subject: [PATCH v13a 9/9] ci: Move to per-job naming for containers

From: Andres Freund <[email-masked]>
Date: Fri, 12 Jun 2026 12:57:36 -0400

Previously we only had two types of containers, "ci" for everything but the
CompilerWarnings job and ci_docs that had the tools necessary to build the
docs as part of CompilerWarnings. But that was unnecessarily heavy for several
of the jobs.  As the pull time is a noticeable performance factor, that's not
great.

Instead use containers that are named by their job. Today some of those are
the same, but after this change we can optimize the containers for their jobs
without a problem.

It probably would make sense to allow over-riding CONTAINER_REPO on a
per-repo/org basis, but that seems better done as a separate change.
