Can I deploy flexvolume only in the alicloud environment

[lixiaopengy]

I tried to deploy flexvolume in a local private environment using the NFS file system

[root@csi1 csi]# kubectl get pod -n kube-system

The bad thing is that the following mistakes always occur. I'm not sure what the problem is. I make sure my NFS is up and running and can be mounted
