Devstack Ceph Plugin

Overview

Devstack plugin to configure Ceph as the storage backend for openstack services

As part of stack.sh:

Installs Ceph (client and server) packages
Creates a Ceph cluster for use with openstack services
Configures Ceph as the storage backend for Cinder, Cinder Backup, Nova, Manila (not by default), and Glance services
Supports Ceph cluster running local or remote to openstack services

As part of unstack.sh | clean.sh:

This plugin also gets used to configure Ceph as the storage backend for the upstream Ceph CI job named gate-tempest-dsvm-full-devstack-plugin-ceph

Enable the plugin in localrc:

enable_plugin devstack-plugin-ceph git://git.openstack.org/openstack/devstack-plugin-ceph
Ceph is setup as the default storage backend for Cinder, Cinder Backup, Glance and Nova services. To disable Ceph disable as the storage backend for a service use the following setting in the localrc file,
```
ENABLE_CEPH_$SERVICE=False
```
where $SERVICE can be CINDER, C_BAK, GLANCE or NOVA corresponding to Cinder, Cinder Backup, Glance, and Nova services respectively.
Ceph can be enabled as the storage backend for Manila with the following setting in the localrc file,
```
ENABLE_CEPH_MANILA=True
```
Make sure that the manila plugin is enabled before devstack-plugin-ceph in the localrc file.
Then run stack.sh and wait for the magic to happen :)
