# What this is: restart script for a test server for Congress, after the 
# host has been restarted (currently the test server does not automatically
# restart)
# 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 restart_congress_testserver.sh
