# This workflow is designed to delete old Google Cloud Platform (GCP) resources to save on costs.
#
# 1. Deletes specific instances in GCP older than a defined number of days.
# 2. Deletes instance templates older than a set number of days.
# 3. Deletes older disks not currently in use, with certain ones prefixed by commit hashes or "zebrad-".
# 4. Deletes cache images from GCP, retaining a specified number of the latest images for certain types like zebrad checkpoint cache, zebrad tip cache, and lightwalletd + zebrad tip cache.
# 5. Deletes unused artifacts from Google Artifact Registry older than a defined number of hours while retaining the latest few.
#
# It uses the gcloud CLI for most of its operations and also leverages specific GitHub Actions like the gcr-cleaner for deleting old images from the Google Artifact Registry.
# The workflow is scheduled to run daily at 0700 UTC.
