# What this is: OpenStack environment file setup for OPNFV deployments. Sets up
# the environment parameters allowing use of OpenStack CLI commands, and as needed
# for OPNFV test scripts.
#
# Status: this is a work in progress, under test.
#
# How to use:
#   $ wget https://git.opnfv.org/cgit/ves/plain/tests/utils/setenv.sh -O [folder]
#   folder: folder to place the script in
#   $ source /tmp/setenv.sh [target]
#   folder: folder in which to put the created admin-openrc.sh file

# TODO: Find a more precise way to determine the OPNFV install... currently
# this assumes that the script is running on the OPNFV jumphost, and 
# Ubuntu=JOID, Centos=Apex

dist=`grep DISTRIB_ID /etc/*-release | awk -F '=' '{print $2}'`
