$ git clone https://github.com/kubernetes-local-volume/kubernetes-local-volume.git
$ cd kubernetes-local-volume

1. To deploy the Plugin on your Kubernetes cluster, please run the following script:

$ make deploy

1. Use command kubectl get pods -n kube-systemto check Local Volume Plugin status like:

NAMESPACE       NAME                                      READY   STATUS      RESTARTS   AGE

kube-system     local-volume-csi-node-server-d4r9t        3/3     Running     0          29m
kube-system     local-volume-csi-node-server-lbk2l        3/3     Running     0          29m
kube-system     local-volume-csi-provisioner-0            1/1     Running     0          29m
kube-system     local-volume-scheduler-5db76cc95f-tmt6n   1/1     Running     0          29m
