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

Start NFS driver

$ sudo ../../_output/flexadapter --endpoint tcp://127.0.0.1:10000 --drivername simplenfs --driverpath ./examples/simplenfs-flexdriver/driver/nfs --nodeid CSINode -v=3

Test

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

Get plugin info

$ csc identity plugininfo --endpoint tcp://127.0.0.1:10000
"NFS"	"0.1.0"

Get supported versions

$ csc identity supportedversions --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 publishvolume --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 unpublishvolume --endpoint tcp://127.0.0.1:10000 --target-path /mnt/nfs nfstestvol
nfstestvol

Get NodeID

$ csc node getid --endpoint tcp://127.0.0.1:10000
