# What this is: An OpenStack Congress policy test. Sets up and validates policy
# creation and execution for:
# 1) Identifying VMs connected to a DMZ (currently identified through a
# specifically-named security group)
# 2) Identifying VMs connected per (1), which are by policy not allowed to be
# (currently implemented through an image tag intended to identify images
# that are "authorized" i.e. tested and secure, to be DMZ-connected)
#
# Status: this is a work in progress, under test. Test (1) has been verified,
# Test (2) is still in development.
#
# How to use:
# Install test server per https://wiki.opnfv.org/copper/academy/congress/test
# # Create Congress policy
# $ source ~/git/copper/tests/adhoc/dmz01_1.sh
# # Create VMs etc that exercise policy
# $ source ~/git/copper/tests/adhoc/dmz01_2.sh
# After test, cleanup with (not yet implemented)
# $ source ~/git/copper/tests/adhoc/dmz01-clean.sh
