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/rexray/gocsi/tree/master/csc
Get plugin info
$ csc identity plugin-info --endpoint tcp://127.0.0.1:10000
"NFS" "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
nfstestvol
Get NodeID
$ csc node get-id --endpoint tcp://127.0.0.1:10000
