# kubectl create -f ./deploy/cpfs/cpfs-plugin.yaml

Note: The plugin log style can be configured by environment variable: LOG_TYPE.

"both": default option, log will be printed both to stdout and host file.

Step 2: Create nginx deploy with csi

# kubectl create -f ./examples/cpfs/deploy.yaml

Step 3: Check status of PVC/PV

# kubectl get pvc
NAME      STATUS    VOLUME       CAPACITY   ACCESS MODES   STORAGECLASS   AGE
cpfs-pvc   Bound     cpfs-csi-pv   5Gi        RWO                           3m

# kubectl get pv
