Currently the playbooks do not allow Ceph to be configured as a backend for Cinder, Glance or Nova. This commit adds a new role called ceph_client to do the required configuration of the hosts and updates the service roles to include the required configuration file changes. This commit requires that a Ceph cluster already exists and does not make any changes to that cluster. ceph_client role, run on the OpenStack service hosts - configures the Ceph apt repo - installs any required Ceph dependencies - copies the ceph.conf file and appropriate keyring file to /etc/ceph - creates the necessary libvirt secrets os_glance role glance-api.conf will set the following variables for Ceph: - [DEFAULT]/show_image_direct_url - [glance_store]/stores - [glance_store]/rbd_store_pool - [glance_store]/rbd_store_user - [glance_store]/rbd_store_ceph_conf - [glance_store]/rbd_store_chunk_size os_nova role nova.conf will set the following variables for Ceph: - [libvirt]/rbd_user - [libvirt]/rbd_secret_uuid - [libvirt]/images_type - [libvirt]/images_rbd_pool - [libvirt]/images_rbd_ceph_conf - [libvirt]/inject_password - [libvirt]/inject_key - [libvirt]/inject_partition - [libvirt]/live_migration_flag os_cinder is not updated because ceph is defined as a backend and that is generated from a dictionary of the config, for an example backend config, see etc/openstack_deploy/openstack_user_config.yml.example pw-token-gen.py is updated so that variables ending in uuid are assigned a UUID.
