Rakshith R 6a4a38869c rbd: consolidate snapshot flatten logic in PrepareVolumeForSnapshot()
This commit consolidates flatten logic checks for cloneDepth
and snapshotLimit in PrepareVolumeForSnapshot. This allows
the function to be called for both CreateSnapshot and
CreateVolumeGroupSnapshot.
Clone Depth check and flattening of grand parent image
now occurs before creation of snapshot starts.
This aligns better with how PVC-PVC clone and
PVC-restore process occurs currently.
Flattening the grandparent image once prevents
flattening of every newly created snapshot.
Snapshot in above para refers to k8s VolumeSnapshot
(which is backed by a rbd image).

Ceph CSI

GitHub release Mergify Status Go Report
Card TODOs CII Best Practices

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.

Overview

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 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.
