#. Create Ceph configuration file in ``/etc/ceph/ceph.conf``
#. Create Ceph keyring file in ``/etc/ceph/ceph.client.<username>.keyring``
Step 1 is done by using Kolla's INI merge mechanism: Create a file in

Cinder
------
Configuring external Ceph for Cinder works very similar to
Glance.
Configuring Cinder for Ceph includes following steps:

Ceph keyrings are deployed per service and placed into
``cinder-volume`` and ``cinder-backup`` directories, put the keyring files
to these directories, for example:

and backup pool.

For cinder (cinder-volume and cinder-backup), glance-api and manila
keyrings behavior has changed and kolla-ansible deployment will not copy
those keys using wildcards (ceph.*), instead will use newly introduced
variables. Your environment may render unusable after an upgrade if your
keys in /etc/kolla/config do not match default values for introduced
variables.
