New container images are built on deploy1002 for every scap sync-world. The images have been accumulating and today deploy1002 currently has 111.5GB of images.
Run docker-gc on deploy servers to keep image storage within configured limits (suggest 20GB/30GB low/high water marks). See https://gerrit.wikimedia.org/r/plugins/gitiles/operations/puppet/+/refs/heads/production/modules/profile/manifests/gitlab/runner.pp#141 for example use.
