Since NFS plugin does not support ControllerServiceCapability, set it to csi.ControllerServiceCapability_RPC_UNKNOWN. Also set ControllerServer to nil instead of using the default because ControllerServer is not implemented in NFS plugin. If this support is added in the future, capabilities need to be added accordingly.
CSI NFS driver
Kubernetes
Requirements
The folllowing 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 requries 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
kubectl -f deploy/kubernetes create
Example Nginx application
Please update the NFS Server & share information in nginx.yaml file.
kubectl -f examples/kubernetes/nginx.yaml create
Using CSC tool
Build nfsplugin
$ make nfs
Start NFS driver
$ sudo ./_output/nfsplugin --endpoint tcp://127.0.0.1:10000 --nodeid CSINode -v=5
Test
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
"NFS" "0.1.0"
Get supported versions
$ csc identity supported-versions --endpoint tcp://127.0.0.1:10000
0.1.0
NodePublish a volume
$ export NFS_SERVER="Your Server IP (Ex: 10.10.10.10)"
$ export NFS_SHARE="Your NFS share"
$ csc node publish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/nfs --attrib server=$NFS_SERVER --attrib share=$NFS_SHARE nfstestvol
nfstestvol
NodeUnpublish a volume
$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/nfs nfstestvol
