# This is a cleanup script for installation of Congress on the Centos 7 based
# OPNFV Controller node as installed per the OPNFV Apex project.
# Prequisites: 
# Presumably something has failed, and any record of the Congress feature
# in OpenStack needs to be removed, so you can try the install again.
#
# Prequisite: 
#  OPFNV install per https://wiki.opnfv.org/display/copper/Apex
# How to use:
#  cd ~/congress/copper/ (or wherever you cloned the copper repo)
#  source /components/congress/install/bash/centos/clean_congress.sh

cd ~
# Setup undercloud environment so we can get overcloud Controller server address
source ~/stackrc

# Get addresses of Controller node(s)
