This charm provides the Glance image service for OpenStack. It is intended to be used alongside the other OpenStack components, starting with the Essex release in Ubuntu 12.04.

Usage

Glance may be deployed in a number of ways. This charm focuses on 3 main configurations. All require the existence of the other core OpenStack services deployed via Juju charms, specifically: mysql, keystone and nova-cloud-controller. The following assumes these services have already been deployed.

Local Storage

In this configuration, Glance uses the local storage available on the server to store image data:

juju deploy glance
juju add-relation glance keystone
juju add-relation glance mysql
juju add-relation glance nova-cloud-controller

Swift backed storage

Glance can also use Swift Object storage for image storage. Swift is often deployed as part of an OpenStack cloud and provides increased resilience and scale when compared to using local disk storage. This configuration assumes that you have already deployed Swift using the swift-proxy and swift-storage charms:

juju deploy glance
juju add-relation glance keystone
juju add-relation glance mysql
juju add-relation glance swift-proxy

This configuration can be used to support Glance in HA/Scale-out deployments.

Ceph backed storage

In this configuration, Glance uses Ceph based object storage to provide scalable, resilient storage of images. This configuration assumes that you have already deployed Ceph using the ceph charm:

juju deploy glance
juju add-relation glance keystone
juju add-relation glance mysql
juju add-relation glance ceph

This configuration can also be used to support Glance in HA/Scale-out deployments.
