Server Version: version.Info{Major:"1", Minor:"9+", GitVersion:"v1.9.0-beta.0-dirty", GitCommit:"a0fb3baa71f1559fd42d1acd9cbdd8a55ab4dfff", GitTreeState:"dirty", BuildDate:"2017-12-13T09:22:09Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}
```
* You can startup the k8s local cluster by executing commands blow:
```bash
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
```
**NOTE**:
<div> Due to opensds using etcd as the database which is same with kubernetes so you should startup kubernetes firstly.
</div>
### [opensds](https://github.com/opensds/opensds) local cluster
* For testing purposes you can deploy OpenSDS referring the [Local Cluster Installation with LVM](https://github.com/opensds/opensds/wiki/Local-Cluster-Installation-with-LVM) wiki.
## Testing steps ##
* Load some ENVs which is setted before.
```bash
source /etc/profile
```
* Download nbp source code.
using git clone
```bash
git clone https://github.com/opensds/nbp.git $GOPATH/src/github.com/opensds/nbp
```
or using go get
```bash
go get -v github.com/opensds/nbp/...
```
* Build the FlexVolume.
```bash
cd $GOPATH/src/github.com/opensds/nbp/flexvolume
go build -o opensds ./cmd/flex-plugin/
```
FlexVolume plugin binary is on the current directory.
* Copy the OpenSDS FlexVolume binary file to k8s kubelet `volume-plugin-dir`.
if you don't specify the `volume-plugin-dir`, you can execute commands blow:
```bash
mkdir -p /usr/libexec/kubernetes/kubelet-plugins/volume/exec/opensds.io~opensds/
cp $GOPATH/src/github.com/opensds/nbp/flexvolume/opensds /usr/libexec/kubernetes/kubelet-plugins/volume/exec/opensds.io~opensds/
```
**NOTE**:
<div>
OpenSDS FlexVolume will get the opensds api endpoint from the environment variable `OPENSDS_ENDPOINT`, if you don't specify it, the FlexVolume will use the default vaule: `http://127.0.0.1:50040`. if you want to specify the `OPENSDS_ENDPOINT` executing command `export OPENSDS_ENDPOINT=http://ip:50040` and restart the k8s local cluster.
</div>
* Build the provisioner docker image.
```bash
cd $GOPATH/src/github.com/opensds/nbp/opensds-provisioner
make container
```
* Create service account, role and bind them.
```bash
cd $GOPATH/src/github.com/opensds/nbp/opensds-provisioner/examples
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.
```bash
kubectl create -f pod-provisioner.yaml
```
Execute `kubectl get pod` to check if the opensds-provisioner is ok.
```bash
root@nbp:~/go/src/github.com/opensds/nbp/opensds-provisioner/examples# kubectl get pod
NAME READY STATUS RESTARTS AGE
opensds-provisioner 1/1 Running 0 42m
```
* You can use the following cammands to test the OpenSDS FlexVolume and Proversioner functions.
Create storage class.
```bash
kubectl create -f sc.yaml # Create StorageClass
```
Execute `kubectl get sc` to check if the storage class is ok.
```bash
root@nbp:~/go/src/github.com/opensds/nbp/opensds-provisioner/examples# kubectl get sc
NAME PROVISIONER AGE
opensds opensds/nbp-provisioner 46m
standard (default) kubernetes.io/host-path 49m
```
Create PVC.
```bash
kubectl create -f pvc.yaml # Create PVC
```
Execute `kubectl get pvc` to check if the pvc is ok.
```bash
root@nbp:~/go/src/github.com/opensds/nbp/opensds-provisioner/examples# kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
opensds-pvc Bound 731da41e-c9ee-4180-8fb3-d1f6c7f65378 1Gi RWO opensds 48m
```
Create busybox pod.
```bash
kubectl create -f pod-application.yaml # Create busybox pod and mount the block storage.
```
Execute `kubectl get pod` to check if the busybox pod is ok.
```bash
root@nbp:~/go/src/github.com/opensds/nbp/opensds-provisioner/examples# kubectl get pod
NAME READY STATUS RESTARTS AGE
busy-pod 1/1 Running 0 49m
opensds-provisioner 1/1 Running 0 50m
```
Execute the `findmnt|grep opensds` to confirm whether the volume has been provided.
If there is some thing that goes wrong, you can check the log files in directory `/var/log/opensds`.
## 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
```
