# What this is: script 1 of 2 for installation of a test server for Congress.
# Status: this is a work in progress, under test.
#
# Prequisite: OPFNV install per https://wiki.opnfv.org/copper/academy/joid
# On jumphost:
# - Congress installed through install_congress_1.sh
# - ~/env.sh created as part of Congress install (install_congress_1.sh)
# How to use:
#   $ source install_congress_testserver_1.sh  <controller_hostname> <user>
# <controller_hostname> is the name of the controller node in MAAS
# and <user> is the name of the account where you are installing this

# Create and Activate the Container
# Earlier versions of the JOID installer installed lxc and created local templates
# but now we have to get the ubuntu template from the controller

if [ $# -lt 2 ]; then
  echo 1>&2 "$0: arguments required <controller_hostname> <user>"
  return 2
