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 https://opendev.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
|
||||
```
|
||||
|
||||
CephFS Native driver that supports native Ceph protocol is used by default.
|
||||
To use CephFS NFS-Ganesha driver that supports NFS protocol add the setting:
|
||||
|
||||
```
|
||||
MANILA_CEPH_DRIVER=cephfsnfs
|
||||
```
|
||||
|
||||
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 :)
|
||||
|
||||
|
||||
# Known Issues / Limitations
|
||||
|
||||
* Rados Gateway with Keystone for Swift - works on Ubuntu only
|
||||
* Tempest test failures when using RGW as swift endpoint
|
||||
* Tempest fails due to verify-tempest-config erroring out, when using RGW as swift endpoint
|
||||
* Patch sent @ https://review.openstack.org/#/c/264179/
|
||||
* Manila with CephFS - for Ubuntu, support only for Trusty Tahr (14.04 LTS) and beyond
|
||||
|
||||
# TODOs

* Fix Rados Gateway with Keystone for Swift on Fedora
