# This is script 1 of 2 for installation of Congress on an Ubuntu 14.04 
# LXC container in the OPNFV Controller node.
# Prequisite: OPFNV install per https://wiki.opnfv.org/copper/academy/joid
#
# On jumphost:
# Download admin-openrc.sh from Horizon and save in ~
# source install_congress_1b.sh <host>
# (copies install_congress_2b.sh to <host> and executes it)
# <hostname> is the name of the host in which to install Congress.
# 
# If "horizon", Congress will be installed in the same LXC as Horizon,
# as necessary for the OpenStack Dashboard Policy plugins to work.
# Otherwise provide the node name of the controller node, where Congress
# will be installed in an LXC (NOTE: Policy plugin for OpenStack dashboard
# does not currently get installed for the LXC-based Congress deploy)
