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.
