      WIP: Do better at cleaning up Docker images · 3e60e9b3
      Daniel Stone authored
      This script is a WIP attempt to create something smarter than docker-gc.
      Currently, docker-gc runs on a cron, and deletes every Docker volume it
      sees (not an issue for ccache as it is mounted into the host
      filesystem), every stopped container it sees, and every image older than
      12-24h (depending on runner disk size and usage).
      This is too blunt a hammer, because it means we have to constantly keep
      downloading common images after they get deleted. It means that we have
      to manually clean up disks when jobs fail, because big jobs can fill up
      the disk - but we also still delete images when we don't need to because
      there's plenty of space.
      The script in this commit takes a smarter approach, by:
        - monitoring the free disk space every five minutes
        - if the free space falls below an acceptable threshold, pruning
          the least-recently-used images until the space comes back above
          the threshold, ignoring Mesa/GStreamer base images as they will
          very likely be immediately re-pulled
        - only as an emergency measure, deleting the Mesa/GStreamer base
          images if required, still on an LRU basis
      However, this script is also completely useless.
      Every gitlab-runner container starts the gitlab-runner-helper image,
      which pulls the Git repository, parses the CI YAML definitions, sets the
      container up to run in the defined context, then executes the actual
      work. The images defined in the CI job are pulled locally, but as they
      are not referred to by any containers, they are all equal on the LRU
      front with a usage time of zero.
      Examining the gitlab-runner code, I tried monitoring the containerd
      events to see when it started each job and get details of the image,
      however it was silent on this - and gRPC + containerd API are really
      painful to use.
      It would probably work to go forward with this script (or something like
      docuum), but taking the image-pull time as the LRU timestamp, and
      continuing to whitelist the base images. In order to get actual-LRU, we
      would have to get sideband information from gitlab-runner about which
      images it was using at which times, or from the GitLab daemon itself.
