# This is a cleanup script for installation of Congress on an Ubuntu 14.04 
# LXC container in the OPNFV Controller node.
# 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/copper/academy/joid
# How to use:
# Install OPNFV per https://wiki.opnfv.org/copper/academy/joid
# $ source ~/git/copper/components/congress/joid/clean_congress.sh <controller_hostname>
# <controller_hostname> is the name of the controller node in MAAS.
