# 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 installed per JOID or Apex installer
# 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>]
# If provided, <controller_hostname> is the name of the controller node in MAAS
# (the parameter is not used for Apex-based installs)
