# garbage_collect() should be called after sourcing.
#
# The garbage collector will remove artifacts of all NON-RELEASE versions from the build cache
# which BOTH
# * exceed the number of builds to keep (defaults to 50)
# AND
# * are older than the minimum purge age (14 days by default)
#
# Note that the min age threshold can lead to MORE than 50 builds being kept if this script
# is run with its default values.
#
# Additionally, the garbage collector will remove all artifacts and directories that do not have
# a version TAG in the scripts repository.
#
# OPTIONAL INPUT
# - Number of (recent) versions to keep. Defaults to 50.
# Explicitly setting this value will reset the minimum age (see below) to 0 days.
# - Minimum age of version tag to be purged, in days. Defaults to 14.
# Only artifacts older than this AND exceeding the builds to keep threshold
# will be removed.
# - PURGE_VERSIONS (Env variable). Space-separated list of versions to purge
# instead of all but the 50 most recent ones.
# Setting this will IGNORE minimum age and number of versions to keep.
# NOTE that only dev versions (not official releases) may be specified.
# This is to prevent accidental deletion of official release tags from the git repo.
# - DRY_RUN (Env variable). Set to "y" to just list what would be done but not
# actually purge anything.
# Flatcar CI automation garbage collector.
# This script removes development (non-official) build artifacts:
# - SDK tarballs, build step containers, and vendor images on buildcache
# - SDK containers built via Github actions (e.g. from PRs).
# See https://github.com/flatcar/scripts/blob/main/.github/workflows/update-sdk.yaml
# - tags from the scripts repository
#
# Garbage collection is based on development (non-official) version tags
# in the scripts repo. The newest 50 builds will be retained,
# all older builds will be purged (50 is the default, see OPTIONAL INPUT above).
