In some environments, a single container, storage, or tunnel network may not be applicable to every host. Each configured provider_network would need to be limited to a particular subset of hosts and the host var keys within the inventory for container_address, storage_address, and tunnel_address will need to be maintained since they're specifically required by various playbooks. Add two new options for configuring provider_networks, 'reference_group' and 'address_prefix'. 'reference_group' for providing a group name that any host must be a member of, in addition to any of the groups listed in 'group_binds', for the network to be applied. 'address_prefix' for overriding the name of the key created for each IP address allocated by a cidr_network. By default, this key is named 'cidr_network'_address, where 'cidr_network' is the given 'ip_from_q' option for a provider network.

Appendix I: Ceph-Ansible integration
|
||
====================================
|
||
|
||
OpenStack-Ansible allows `Ceph storage <https://ceph.com>`_ cluster integration
|
||
using the roles maintained by the `Ceph-Ansible`_ project>. Deployers can
|
||
enable the ``ceph-install`` playbook by adding hosts to the
|
||
``ceph-mon_hosts`` and ``ceph-osd_hosts`` groups in
|
||
``openstack_user_config.yml``, and then configuring `Ceph-Ansible specific vars
|
||
<https://github.com/ceph/ceph-ansible/blob/master/group_vars/all.yml.sample>`_
|
||
in the OpenStack-Ansible ``user_variables.yml`` file.
