melanie witt fe06350c48 Add release key for installing packages from ceph.com 
In commit bb773e7285 the key for
verifying release packages from ceph.com was removed when support for
the ceph package mirrors was added. However, it is still needed for
non-gate case of fetching packages from ceph.com, so this adds it
back in that case.

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

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 :)

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

TODOs

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