Madhu Rajanna b085577a4f rbd: add skipForceFlatten flag
added skipForceFlatten flag to skip
the image deptha and skip image flattening.
This will be very useful if the kernel is
not listed in cephcsi which supports deep
flatten fauture.

Ceph CSI

Go Report
Card Build
Status

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

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.

NOTE:

  • csiv0.3 is deprecated with release of csi v1.1.0
