+* You can startup the k8s local cluster by executing commands blow:
+
+ ```
+ cd $HOME
+ git clone https://github.com/kubernetes/kubernetes.git
+ cd $HOME/kubernetes
+ git checkout v1.9.0
+ make
+ echo alias kubectl='$HOME/kubernetes/cluster/kubectl.sh' >> /etc/profile
+ RUNTIME_CONFIG=settings.k8s.io/v1alpha1=true AUTHORIZATION_MODE=Node,RBAC hack/local-up-cluster.sh -O
+ ```
+
+
+### [opensds](https://github.com/opensds/opensds) local cluster
+* For testing purposes you can deploy OpenSDS local cluster referring to ```ansible/README.md```. Besides, you need to deploy opensds flexvolume plugin refering to ```nbp-ansible/README.md```.
+
+## Testing steps ##
+
+* Create service account, role and bind them.
+ ```
+ cd /opt/opensds-k8s-linux-amd64/provisioner
+ kubectl create -f serviceaccount.yaml
+ kubectl create -f clusterrole.yaml
+ kubectl create -f clusterrolebinding.yaml
+ ```
+
+* Change the opensds endpoint IP in pod-provisioner.yaml
+The IP (192.168.56.106) should be replaced with the OpenSDS osdslet actual endpoint IP.
+ ```yaml
+ kind: Pod
+ apiVersion: v1
+ metadata:
+ name: opensds-provisioner
+ spec:
+ serviceAccount: opensds-provisioner
+ containers:
+ - name: opensds-provisioner
+ image: opensdsio/opensds-provisioner
+ securityContext:
+ args:
+ - "-endpoint=http://192.168.56.106:50040" # should be replaced
+ imagePullPolicy: "IfNotPresent"
+ ```
+
+* Create provisioner pod.
+ ```
+ kubectl create -f pod-provisioner.yaml
+ ```
+
+* You can use the following cammands to test the OpenSDS FlexVolume and Proversioner functions.
+
+ ```
+ kubectl create -f sc.yaml # Create StorageClass
+ kubectl create -f pvc.yaml # Create PVC
+ kubectl create -f pod-application.yaml # Create busybox pod and mount the block storage.
+ ```
+
+ Execute the `findmnt|grep opensds` to confirm whether the volume has been provided.
+
+## Clean up steps ##
+
+```
+kubectl delete -f pod-application.yaml
+kubectl delete -f pvc.yaml
+kubectl delete -f sc.yaml
+
+kubectl delete -f pod-provisioner.yaml
+kubectl delete -f clusterrolebinding.yaml
+kubectl delete -f clusterrole.yaml
+kubectl delete -f serviceaccount.yaml
+```
