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:

• 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

How to use

• 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 :)

TODOs

• Configuring Rados Gateway with Keystone for Swift
• Add support for Ceph Infernalis release
• Add support for distro specific ceph repos
• Add Manila support for non-Ubuntu systems
