# Create a new Job in OCP that runs the jbb-validate container once. This
# script will wait for completion of the validation, and uses the result of the
# container to report the status.
#
# Usage:
# - arguments to the script can be "validate" or "deploy"
# - the GIT_REF environment variable is injected in the batch job so that it
#   can use a particular GitHub PR
#

# error out in case a command fails
