# This workflow runs daily to clean up images older than the cut-off
# period specified in each `snok/container-retention-policy`.
#
# Both testing and production images are being cleaned up, with separate
# retention policies.
#
# For `postgresql-trunk-testing` images:
# - Delete everything that's older than 1 week
#
# For `postgresql-trunk` images:
# - Delete all rolling-upgrade-e2e tags older than 1 week (these are retags required only by E2Es)
# - Delete `-minimal` images older than 1 week, keeping the most recent tag for each distro
# - Delete `-standard` images older than 1 week, keeping the most recent tag for each distro
# - Delete `-postgis` images older than 1 week, keeping the most recent tag for each distro
# - Delete untagged/orphaned layers older than 1 week
#
# Tags produced by build.yml / build-commitfest.yml are never deleted.
