Fetch port information from a TripleO overcloud Heat stack

get-role-ports.sh

#!/bin/bash

# This script will fetch IP addresses assigned to ports on servers belonging
# to a particular role in the overcloud Heat stack. It's not optimized for everyday
# use and takes a while to complete, as it makes many Heat queries. This does not include
# e.g. VIPs.

# Run this script for each role you are interested in. Example usage:
# $ source stackrc
# $ bash get-role-ports.sh overcloud Controller
