ShyamsundarR e5e332eded Use correct file descriptor to parse errors 
File descriptors in use to parse errors from a few command
invocations were incorrect. This led to inability to detect
certain errors cases and act accordingly.

One of the easiest noticeable issues was when an image is deleted
but its RADOS keys and maps are still intact. In such cases
the DeleteVolume call always errored out unable to find the
image rather than, proceed with cleaning up the RADOS objects
and returning a success.

The original method of using stdout was incorrect, as the command
was tested from within a shell script and the scripts STDIN/OUT/ERR
was redirected to understand behavior. This is now tested using just
the CLI in question, and also examining Ceph code, and further
testing a couple of edge conditions by deleting backing images
for PVs

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: 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
