# This is script 1 of 2 for installation of Congress on the OPNFV Controller
# node as installed via JOID or Apex (Fuel and Compass not yet verified).
# 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 install script as below, optionally specifying the 
#   branch to use as a URL parameter, e.g. ?h=stable%2Fbrahmaputra
# $ cd ~
# $ wget https://git.opnfv.org/cgit/copper/plain/components/congress/install/bash/install_congress_1.sh
# $ wget https://git.opnfv.org/cgit/copper/plain/components/congress/install/bash/install_congress_2.sh
# $ bash install_congress_1.sh [openstack-branch]
#   optionally specifying the branch identifier to use for OpenStack
#
