# To test the release process, this script attempts
# to use a Google cloudbuild configuration to create
# release artifacts locally.
#
# See https://cloud.google.com/cloud-build/docs/build-debug-locally
#
# Usage: from the repo root, enter:
#
#   ./releasing/localbuild.sh kustomize/v1.2.3
#
# or some other valid tag value.
#
# IMPORTANT:
#   The process clones the repo at the given tag,
#   so the repo must have the tag applied upstream.
#   Either use an old tag, or disable the cloud build
#   trigger so that a new testing tag can be applied
#   without setting off a cloud build.
