## 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
```
