# This script registers a new OpenStack region in Keystone.
# It relies on availability of the following environment variables
#
# $NEW_PUBLIC_URL - public URL for the OpenStack services
# $NEW_INTERNAL_URL - internal URL for the OpenStack services
# $NEW_ADMIN_URL - admin URL for the OpenStack services. Typically the same as internal URL
# $NEW_REGION - new region name. E.g. RegionTwo
#
# Invoke the script on the master region - the region which hosts a centralized Keystone instance.
# Additional services can be register using the following pattern:
#
# openstack endpoint create --publicurl "" --adminurl "" --internalurl "" --region ${region} <service>
