CSI driver for Ceph

Prasanna Kumar Kalever 4f40213d8e rbd: fix rbd-nbd io-timeout to never abort
With the tests at CI, it kind of looks like that the IO is timing out after
30 seconds (default with rbd-nbd). Since we have tweaked reattach-timeout
to 300 seconds at ceph-csi, we need to explicitly set io-timeout on the
device too, as it doesn't make any sense to keep
io-timeout < reattach-timeout

Hence we set io-timeout for rbd nbd to 0. Specifying io-timeout 0 tells
the nbd driver to not abort the request and instead see if it can be
restarted on another socket.

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

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

Support Matrix

Ceph-CSI features and available versions

Please refer rbd nbd mounter for its support details.
