# TO use this to TEST:
# 1. run cloud-installer and wait until everything is up, including letting the default charm pull down an image (or an error if you require proxies)
# 2. connect to the install host (multi) or top container (single)
# 3. juju ssh nova-cloud-controller/0
# 3a. source /tmp/openstack-admin*
# 3b. glance image-list (there should be one or zero)
# 3c. if there's an image, glance image-delete <that image's ID>
# 4. clone this script on the juju host
