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
|
|
* (Optionally) Sets up & configures Rados gateway (aka rgw or radosgw) as a Swift endpoint with Keystone integration
|
|
* Set ```ENABLE_CEPH_RGW=True``` in your ```localrc```
|
|
* Supports Ceph cluster running local or remote to openstack services
|
|
|
|
As part of ```unstack.sh``` | ```clean.sh```:
|
|
|
|
* Tears down the Ceph cluster and its related services
|
|
|
|
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```
|
|
|
|
|
|
# Usage
|
|
|
|
* To get started quickly, just enable the plugin in your ```local.conf```:
|
|
|
|
```enable_plugin devstack-plugin-ceph git://git.openstack.org/openstack/devstack-plugin-ceph```
|
|
|
|
Run ```stack.sh``` in your devstack tree and boom! You're good to go.
|
|
|
|
* Ceph is setup as the default storage backend for Cinder, Cinder Backup,
|
|
Glance and Nova services. You have the ability to control each of the
|
|
enabled services with the following configuration in your ```local.conf```:
|
|
|
|
```
|
|
ENABLE_CEPH_CINDER=True # ceph backend for cinder
|
|
ENABLE_CEPH_GLANCE=True # store images in ceph
|
|
ENABLE_CEPH_C_BAK=True # backup volumes to ceph
|
|
ENABLE_CEPH_NOVA=True # allow nova to use ceph resources
|
|
```
|
|
|
|
Change any of the above lines to ```False``` to disable that feature
|
|
specifically.
|
|
|
|
* Ceph can be enabled as the storage backend for Manila with the following
|
|
setting in your ```local.conf```:
|
|
|
|
```
|
|
ENABLE_CEPH_MANILA=True
|
|
```
|
|
|
|
Make sure that the manila plugin is enabled before devstack-plugin-ceph in
|
|
the ```local.conf``` file.
|
|
|
|
* Then run ```stack.sh``` and wait for the _magic_ to happen :)
