CSI driver for Ceph

Benoît Knecht 507844c9b1 rbd: Use rados namespace when getting clone depth
When the Ceph user is restricted to a specific namespace in the pool, it is
crucial that evey interaction with the cluster is done within that namespace.
This wasn't the case in `getCloneDepth()`.

This issue was causing snapshot creation to fail with

> Failed to check and update snapshot content: failed to take snapshot of the
> volume X: "rpc error: code = Internal desc = rbd: ret=-1, Operation not
> permitted"

Ceph CSI

GitHub release Mergify Status Go Report
Card TODOs CII Best Practices

This repo contains Ceph Container Storage Interface (CSI) driver for RBD, CephFS and kubernetes sidecar deployment yamls of provisioner, attacher, resizer, driver-registrar and snapshotter for supporting CSI functionalities.

Overview

Ceph CSI plugins implement an interface between CSI enabled Container Orchestrator (CO) and Ceph cluster. It allows 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 RBD and CephFS CSI plugins, see examples in examples/.
  • Stale resource cleanup, please refer cleanup doc.

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 on Kubernetes environments.

Ceph CSI Version Container Orchestrator Name Version Tested
v3.6.1 Kubernetes v1.21, v1.22, v1.23
v3.6.0 Kubernetes v1.21, v1.22, v1.23
v3.5.1 Kubernetes v1.21, v1.22, v1.23
v3.5.0 Kubernetes v1.21, v1.22, v1.23
v3.4.0 Kubernetes v1.20, v1.21, v1.22

There is work in progress to make this CO independent and thus support other orchestration environments (Nomad, Mesos..etc) in the future.

NOTE:

The supported window of Ceph CSI versions is known as "N.(x-1)": (N (Latest major release) . (x (Latest minor release) - 1)).

For example, if Ceph CSI latest major version is 3.6.0 today, support is provided for the versions above 3.5.0. If users are running an unsupported Ceph CSI version, they will be asked to upgrade when requesting support for the cluster.
