# What this is: Cleanup script for the test dmz01.sh
#
# Status: this is a work in progress, under test. 
#
# Prequisite: OPFNV installed per JOID or Apex installer
# - OpenStack CLI environment variables setup
# How to use:
#   Install Congress test server per https://wiki.opnfv.org/copper/academy
#   # Create Congress policy and resources that exercise policy
#   $ bash dmz.sh
#   # After test, cleanup
#   $ bash dmz-clean.sh
