 ### Test using csc
 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
-"csi-hostpath"  "0.1.0"
+$ csc identity plugin-info --endpoint $endpoint
+"hostpath.csi.k8s.io"  "v1.x.x-xx-xxx"

 #### Create a volume
 ```
-$ csc controller new --endpoint tcp://127.0.0.1:10000 --cap 1,block CSIVolumeName
+$ csc controller new --endpoint $endpoint --cap 1,block CSIVolumeName
 CSIVolumeID

 #### Delete a volume
 ```
-$ csc controller del --endpoint tcp://127.0.0.1:10000 CSIVolumeID
+$ csc controller del --endpoint $endpoint CSIVolumeID
