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](https://github.com/ceph/ceph-csi/blob/devel/docs/rbd/deploy.md) and for CephFS plugin configuration and deployment please refer [cephFS doc](https://github.com/ceph/ceph-csi/blob/devel/docs/cephfs/deploy.md). - For example usage of the RBD and CephFS CSI plugins, see examples in `examples/`. - Stale resource cleanup, please refer [cleanup doc](docs/resource-cleanup.md). NOTE: - Ceph CSI **`Arm64`** support is experimental. ## Project status Status: **GA** ## Known to work CO platforms Ceph CSI drivers are currently developed and tested **exclusively** in Kubernetes environments. | Ceph CSI Version | Container Orchestrator Name | Version Tested | | -----------------| --------------------------- | -------------------| | v3.13.0 | Kubernetes | v1.29, v1.30, v1.31| | v3.12.3 | Kubernetes | v1.29, v1.30, v1.31| 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. ## Support Matrix ### Ceph-CSI features and available versions Please refer [rbd nbd mounter](./docs/design/proposals/rbd-nbd.md#support-matrix) for its support details. | Plugin | Features | Feature Status | CSI Driver Version | CSI Spec Version | Ceph Cluster Version | Kubernetes Version | | ------ | --------------------------------------------------------- | -------------- | ------------------ | ---------------- | -------------------- | ------------------ | | RBD | Dynamically provision, de-provision Block mode RWO volume | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision Block mode RWX volume | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision Block mode RWOP volume| Alpha | >= v3.5.0 | >= v1.5.0 | Pacific (>=v16.2.0) | >= v1.22.0 | | | Dynamically provision, de-provision File mode RWO volume | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode RWOP volume | Alpha | >= v3.5.0 | >= v1.5.0 | Pacific (>=v16.2.0) | >= v1.22.0 | | | Provision File Mode ROX volume from snapshot | Alpha | >= v3.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision File Mode ROX volume from another volume | Alpha | >= v3.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.16.0 | | | Provision Block Mode ROX volume from snapshot | Alpha | >= v3.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision Block Mode ROX volume from another volume | Alpha | >= v3.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.16.0 | | | Creating and deleting snapshot | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision volume from snapshot | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision volume from another volume | GA | >= v1.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.16.0 | | | Expand volume | Beta | >= v2.0.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.15.0 | | | Volume/PV Metrics of File Mode Volume | GA | >= v1.2.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.15.0 | | | Volume/PV Metrics of Block Mode Volume | GA | >= v1.2.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.21.0 | | | Topology Aware Provisioning Support | Alpha | >= v2.1.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | CephFS | Dynamically provision, de-provision File mode RWO volume | GA | >= v1.1.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode RWX volume | GA | >= v1.1.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode ROX volume | Alpha | >= v3.0.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode RWOP volume | Alpha | >= v3.5.0 | >= v1.5.0 | Pacific (>=v16.2.0) | >= v1.22.0 | | | Creating and deleting snapshot | GA | >= v3.1.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Creating and deleting volume group snapshot | Alpha | >= v3.11.0 | >= v1.9.0 | Squid (>=v19.0.0) | >= v1.31.0 | | | Provision volume from snapshot | GA | >= v3.1.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision volume from another volume | GA | >= v3.1.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.16.0 | | | Expand volume | Beta | >= v2.0.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.15.0 | | | Volume/PV Metrics of File Mode Volume | GA | >= v1.2.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.15.0 | | NFS | Dynamically provision, de-provision File mode RWO volume | Alpha | >= v3.6.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode RWX volume | Alpha | >= v3.6.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode ROX volume | Alpha | >= v3.6.0 | >= v1.0.0 | Pacific (>=v16.2.0) | >= v1.14.0 | | | Dynamically provision, de-provision File mode RWOP volume | Alpha | >= v3.6.0 | >= v1.5.0 | Pacific (>=v16.2.0) | >= v1.22.0 | | | Expand volume | Alpha | >= v3.7.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.15.0 | | | Creating and deleting snapshot | Alpha | >= v3.7.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision volume from snapshot | Alpha | >= v3.7.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.17.0 | | | Provision volume from another volume | Alpha | >= v3.7.0 | >= v1.1.0 | Pacific (>=v16.2.0) | >= v1.16.0 | `NOTE`: The `Alpha` status reflects possible non-backward compatible changes in the future, and is thus not recommended for production use. ### CSI spec and Kubernetes version compatibility Please refer to the [matrix](https://kubernetes-csi.github.io/docs/#kubernetes-releases) in the Kubernetes documentation. ##
