#
# What this is: Installer for an OpenStack API test environment for Congress.
# Generally, this script is only needed if you want to setup an environment
# not already provided by the OPNFV installer. In most cases it's expected
# that adhoc tests will be run on the Jumphost with the needed OpenStack
# CLI clients etc already installed, and the OpenStack CLI credentials 
# needed by the test commands already EXPORTed to the shell environment.
# To avoid potential conflicts with the test user account setup (e.g. 
# installed python packages), this script sets up and activates a virtualenv,
# then installs the needed OpenStack CLI clients under it.
#
# Status: this is a work in progress, under test.
#
# Prequisite: OPFNV installed per JOID or Apex installer
# On jumphost:
# - Congress installed through JOID or Apex, or install_congress_1.sh
# - For Apex installs, on the jumphost, ssh to the undercloud VM and
#     $ su stack
# How to use:
#   Retrieve the copper install script as below, optionally specifying the 
#   branch to use as a URL parameter, e.g. ?h=stable%2Fbrahmaputra
# $ wget https://git.opnfv.org/cgit/copper/plain/components/congress/test-webapp/setup/install_congress_cli_test_environment.sh
# $ bash install_congress_cli_test_environment.sh
