Existing config maps are now replaced with rados omaps that help store information regarding the requested volume names and the rbd image names backing the same. Further to detect cluster, pool and which image a volume ID refers to, changes to volume ID encoding has been done as per provided design specification in the stateless ceph-csi proposal. Additional changes and updates, - Updated documentation - Updated manifests - Updated Helm chart - Addressed a few csi-test failures Signed-off-by: ShyamsundarR <srangana@redhat.com> |

Ceph CSI
Container Storage Interface (CSI) driver, provisioner, and attacher for Ceph RBD and CephFS.
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 and CephFS CSI plugins,
see documentation in
docs/. - 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.
