# What this is: Deployment script for the VNF Event Stream (VES) Reference VNF
# and Test Collector. Runs the VES Collector in a docker container on the 
# OPNFV jumphost, and the VES Reference VNF as an OpenStack VM.
#
# Status: this is a work in progress, under test.
#
# How to use:
#   $ git clone https://gerrit.opnfv.org/gerrit/ves
#   $ cd ves/tests
#   $ bash VES_Reference.sh [setup|start|run|stop|clean]
#   setup: setup test environment
#   start: install blueprint and run test
#   run: setup test environment and run test
#   stop: stop test and uninstall blueprint
#   clean: cleanup after test
