# This is a cleanup script for installation of Congress on the OPNFV Controller
# node as installed via JOID or Apex (Fuel and Compass not yet verified).
# Presumably something has failed, and any record of the Congress feature
# in OpenStack needs to be removed, so you can try the install again.
# Prerequisites: 
# - OPFNV installed via JOID or Apex
# - For Apex installs, on the jumphost, ssh to the undercloud VM and
#     $ su stack
# - For JOID installs, admin-openrc.sh saved from Horizon to ~/admin-openrc.sh
# - Retrieve the copper removal script as below
# $ cd ~
# $ wget https://git.opnfv.org/cgit/copper/plain/components/congress/install/bash/clean_congress.sh
# $ bash clean_congress.sh
