# What this is: Cleanup script for the test dmz01.sh
#
# Status: this is a work in progress, under test. 
#
# Prerequisite: 
# - OpenStack deployment with Congress service activated.
# - OpenStack CLI environment variables setup e.g. via admin-openrc.sh script.
# How to use:
#   # Create Congress policy and resources that exercise policy
#   $ bash dmz.sh
#   # After test, cleanup with
#   $ bash dmz-clean.sh
