# Lists all remote tags on the upstream, which gives tags in format:
# "<commit> ref/tags/<tag>". Strips commit + tag prefix, filters out tags for v1+,
# and manually removes v1.2.0-alpha.1, since that version's manifest contains
# duplicate CRD resources (2 CRDs with the same name) which in turn can cause problems
# with the versionchecker test.
# Open question: how do we decide when to refresh this target?

# The file "release-version" gets updated whenever git describe --tags changes. This is
# used by the bin/containers/*.tar.gz targets to make sure the containers, which use the
# "git describe --tags" string as their tag, get rebuilt whenever you check out a different
# commit. If we didn't do this, the Helm chart bin/cert-manager-*.tgz would refer to an
# image tag that doesn't exist in bin/containers/*.tar.gz.
