`Rook <https://rook.io/> `_ deploys and manages Ceph clusters running
in Kubernetes, while also enabling management of storage resources and
2020-03-17 13:58:57 +00:00
provisioning via Kubernetes APIs. We recommend Rook as the way to run Ceph in
2020-03-15 13:45:46 +00:00
Kubernetes or to connect an existing Ceph storage cluster to Kubernetes.
2020-03-11 15:28:28 +00:00
2020-03-17 13:58:57 +00:00
* Rook only supports Nautilus and newer releases of Ceph.
2020-03-15 13:45:46 +00:00
* Rook is the preferred method for running Ceph on Kubernetes, or for
connecting a Kubernetes cluster to an existing (external) Ceph
cluster.
2020-03-17 13:58:57 +00:00
* Rook supports the new orchestrator API. New management features
2020-03-15 13:45:46 +00:00
in the CLI and dashboard are fully supported.
