This repo contains the Ceph Container Storage Interface (CSI) driver for RBD, CephFS and Kubernetes sidecar deployment YAMLs to support CSI functionality: provisioner, attacher, resizer, driver-registrar and snapshotter.
Ceph CSI plugins implement an interface between a CSI-enabled Container Orchestrator (CO) and Ceph clusters. They enable dynamically provisioning Ceph volumes and attaching them to workloads.
Independent CSI plugins are provided to support RBD and CephFS backed volumes,
- For details about configuration and deployment of RBD plugin, please refer rbd doc and for CephFS plugin configuration and deployment please refer cephFS doc.
- For example usage of the RBD and CephFS CSI plugins, see examples in
examples/. - Stale resource cleanup, please refer cleanup doc.
NOTE:
- Ceph CSI
Arm64support is experimental.
Status: GA
Ceph CSI drivers are currently developed and tested exclusively in Kubernetes environments.
| Ceph CSI Version | Container Orchestrator Name | Version Tested |
|---|---|---|
| v3.10.0 | Kubernetes | v1.26, v1.27, v1.28 |
| v3.9.0 | Kubernetes | v1.25, v1.26, v1.27 |
There is work in progress to make this CO-independent and thus support other orchestration environments (Nomad, Mesos..etc).
NOTE:
The supported window of Ceph CSI versions is "N.(x-1)": (N (Latest major release) . (x (Latest minor release) - 1)).
For example, if the Ceph CSI latest major version is 3.9.0 today, support is
provided for the versions above 3.8.0. If users are running an unsupported
Ceph CSI version, they will be asked to upgrade when requesting support.
Please refer rbd nbd mounter for its support details.
