Madhu Rajanna c3c87f2ef3 rbd: consider remote image health for primary 
To consider the image is healthy during the Promote
operation currently we are checking only the image
state on the primary site. If the network is flaky
or the remote site is down the image health is
not as expected. To make sure the image is healthy
across the clusters check the state on both local
and the remote clusters.

Ceph CSI

GitHub release Go Report Card TODOs

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
v3.6.0 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.
