CSI Cinder driver

Kubernetes

Requirements

The following feature gates and runtime config have to be enabled to deploy the driver.

FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true
RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true"

Mountprogpation requires support for privileged containers. So, make sure privileged containers are enabled in the cluster.

Example local-up-cluster.sh

ALLOW_PRIVILEGED=true FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true" LOG_LEVEL=5 hack/local-up-cluster.sh

Deploy

Encode your cloud.conf file content using base64.

base64 -w 0 cloud.conf

Update cloud.conf configuration in deploy/kubernetes/csi-secret-cinderplugin.yaml file by using the result of the above command.

kubectl -f deploy/kubernetes create

Example Nginx application

kubectl -f examples/kubernetes/nginx.yaml create

Using CSC tool

Start Cinder driver

$ sudo ./_output/cinderplugin --endpoint tcp://127.0.0.1:10000 --cloud-config /etc/cloud.conf --nodeid CSINodeID

Test using csc

Get csc tool from https://github.com/thecodeteam/gocsi/tree/master/csc

Get plugin info

$ csc identity plugin-info --endpoint tcp://127.0.0.1:10000
"csi-cinderplugin"  "0.1.0"

Get supported versions

$ csc identity supported-versions --endpoint tcp://127.0.0.1:10000
0.1.0

Create a volume

$ csc controller new --endpoint tcp://127.0.0.1:10000 CSIVolumeName
CSIVolumeID

Delete a volume

$ csc controller del --endpoint tcp://127.0.0.1:10000 CSIVolumeID
