Glance HA/Scale-out
===================
The Glance charm can also be used in a HA/scale-out configuration using
the hacluster charm:
juju deploy -n 3 glance
juju deploy hacluster haglance
juju set glance vip=<virtual IP address to access glance over>
juju add-relation glance haglance
juju add-relation glance mysql
juju add-relation glance keystone
juju add-relation glance nova-cloud-controller
juju add-relation glance ceph|swift-proxy
In this configuration, 3 service units host the Glance image service;
API requests are load balanced across all 3 service units via the
configured virtual IP address (which is also registered into Keystone
as the endpoint for Glance).
Note that Glance in this configuration must be used with either Ceph or
Swift providing backing image storage.
