~~~~~~~~~~~~~~~~~~~~~
OpenStack-Ansible allows `Ceph storage <https://ceph.io>`_ cluster
integration in two ways:
integration in three ways:
* connecting to your own ceph cluster by pointing to its information
in ``user_variables.yml``. This is described
* connecting to your own pre-deployed ceph cluster by pointing to its
information in ``user_variables.yml`` and allowing openstack-ansible
to ssh to the ceph monitors to retrieve the contents of ceph.conf
and the keyrings.
* connecting to your own pre-deployed ceph cluster by pointing to its
information in ``user_variables.yml`` and providing data to populate
ceph.conf and ceph keyring files on the deploy host. This is described
`here <https://docs.openstack.org/openstack-ansible-ceph_client/latest/config-from-file.html>`_.
* deploying a ceph cluster by using the roles maintained by the
`Ceph-Ansible`_ project. Deployers can enable the ``ceph-install``
playbook by adding hosts to the ``ceph-mon_hosts``, ``ceph-osd_hosts`` and
``ceph-rgw_hosts`` groups in ``openstack_user_config.yml``, and then
configuring `Ceph-Ansible specific vars
No ssh access by openstack-ansible is required to the ceph cluster.
* deploying a ceph cluster as part of the openstack-ansible deployment
by using the roles maintained by the `Ceph-Ansible`_ project. Deployers
can enable the ``ceph-install`` playbook by adding hosts to the
``ceph-mon_hosts``, ``ceph-osd_hosts`` and ``ceph-rgw_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.
