--- prelude: > Deployment of Ceph in containers is implemented using a Mistral workflow. other: - | It is possible to deploy Ceph in docker containers in the overcloud. This is implemented by triggering `ceph-ansible` via a Mistral workflow. A new `CephAnsibleExtraConfig` parameter has been added to the templates and can be used to provide arbitrary config variables consumed by `ceph-ansible`. The pre-existing template params consumed by the TripleO Pike release to drive `puppet-ceph` continue to work and are translated, when possible, into their equivalent `ceph-ansible` variable. To enable the deployment of Ceph in containers use `environments/ceph-ansible/ceph-ansible.yaml` when deploying the overcloud.
