# This is intended to run either locally (in which case a push is not
# necessary) or in a CI job (where the results should be pushed to a
# registry for use in later CI test jobs). Images are tagged locally with
# both the base name (e.g. "test-target-base") and with the prefix given;
# then only the prefixed name is pushed if --push is specified, assuming
# any necessary credentials are available for the push. The same prefix
# can then be used for the testing script. By default a local (non-registry)
# prefix is used and no push can occur. To push to e.g. dockerhub:
#
# ./build-images.sh --push --prefix=docker.io/openshift/ansible-integration-
