Ceph CSI

Go Report Card Build Status

This repo contains [Container Storage Interface(CSI)] (https://github.com/container-storage-interface/) Ceph CSI driver for RBD, CephFS and kubernetes sidecar deployment yamls of provisioner, attacher, node-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/.

Project status

Status: Alpha

The alpha status reflects possible non-backward compatible changes in the future, and is thus not recommended for production use. There is work in progress that would change on-disk metadata for certain operations, possibly breaking backward compatibility.

Supported CO platforms

Ceph CSI drivers are currently developed and tested exclusively on Kubernetes environments. There is work in progress to make this CO independent and thus support other orchestration environments in the future.

For Kubernetes versions 1.11 and 1.12, please use 0.3 images and deployments.

For Kubernetes versions 1.13 and above, please use 1.0 images and deployments.
