+### [kubernetes](https://github.com/kubernetes/kubernetes) local cluster
+* You can startup the lastest k8s local cluster by executing commands blow:
+
+ ```
+ cd $HOME
+ git clone https://github.com/kubernetes/kubernetes.git
+ cd $HOME/kubernetes
+ make
+ echo alias kubectl='$HOME/kubernetes/cluster/kubectl.sh' >> /etc/profile
+ ALLOW_PRIVILEGED=true FEATURE_GATES=CSIPersistentVolume=true,MountPropagation=true RUNTIME_CONFIG="storage.k8s.io/v1alpha1=true" LOG_LEVEL=5 hack/local-up-cluster.sh
+ ```
+
+### [opensds](https://github.com/opensds/opensds) local cluster
+* For testing purposes you can deploy OpenSDS referring the [OpenSDS Cluster Installation through Ansible](https://github.com/opensds/opensds/wiki/OpenSDS-Cluster-Installation-through-Ansible) wiki. Besides, you need to deploy opensds csi plugin refering to ```nbp-ansible/README.md```.
+
+## Testing steps ##
+
+* Change the workplace
+
+ ```
+ cd /opt/opensds-k8s-v0.1.0-linux-amd64
+ ```
+
+* Configure opensds endpoint IP
+
+ ```
+ vim csi/deploy/kubernetes/csi-configmap-opensdsplugin.yaml
+ ```
+
+ The IP (127.0.0.1) should be replaced with the opensds actual endpoint IP.
+ ```yaml
+ kind: ConfigMap
+ apiVersion: v1
+ metadata:
+ name: csi-configmap-opensdsplugin
+ data:
+ opensdsendpoint: http://127.0.0.1:50040
+ ```
+
+* Create opensds CSI pods.
+
+ ```
+ kubectl create -f csi/deploy/kubernetes
+ ```
+
+ After this three pods can be found by ```kubectl get pods``` like below:
+
+ - csi-provisioner-opensdsplugin
+ - csi-attacher-opensdsplugin
+ - csi-nodeplugin-opensdsplugin
+
+ You can find more design details from
+ [CSI Volume Plugins in Kubernetes Design Doc](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/container-storage-interface.md)
+
+* Create example nginx application
+
+ ```
+ kubectl create -f csi/examples/kubernetes/nginx.yaml
+ ```
+
+ This example will mount a opensds volume into ```/var/lib/www/html```.
+
+ You can use the following command to inspect into nginx container to verify it.
+
+ ```
+ docker exec -it <nginx container id> /bin/bash
+ ```
+
+## Clean up steps ##
+
+Clean up example nginx application and opensds CSI pods by the following commands.
+
+```
+kubectl delete -f csi/examples/kubernetes/nginx.yaml
+kubectl delete -f csi/deploy/kubernetes
+```
