cloudbuild-tag.yaml

# Used for building tagged releases.
# It updates the "latest" tag in the corresponding GCR repos
# if the current SemVer is the most recent.
#
# This does not actually build images; it copies candidates
# built in the staging project instead. These images should have
# been built by cloudbuild.yaml, which should be triggered on
# every new commit.
