# This sets up a developer testing environment that can be used with various
# openstack projects (mainly for taskflow, but for others it should work
# fine also).
#
# Some things to note:
#
# - The mysql server that is setup is *not* secured.
# - The zookeeper server that is setup is *not* secured.
# - The downloads from external services are *not* certificate verified.
#
# Overall it should only be used for testing/developer environments (it was
# tested on ubuntu 14.04 and rhel 6.x, for other distributions some tweaking
# may be required).
