## Prerequisite ##
### ubuntu
* Version information
```
root@proxy:~# cat /etc/issue
Ubuntu 16.04.2 LTS \n \l
```

### [kubernetes](https://github.com/kubernetes/kubernetes) local cluster
* You can startup the v1.9.0 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
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 refering to ```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
```
