Verify the OpenStack cloud provider after deployment¶

After you enable the OpenStack cloud provider as described in Enable the OpenStack cloud provider and deploy it together with your Kubernetes cluster, verify that it has been successfully deployed using the procedure below.

To verify the OpenStack cloud provider:

1. Log in to any Kubernetes Master node.

2. Create a claim1.yaml file with the following content:

   kind: PersistentVolumeClaim
   apiVersion: v1
   metadata:
     name: claim1
   spec:
     storageClassName: cinder
     accessModes:
       - ReadWriteOnce
     resources:
       requests:
         storage: 1Gi
   

3. Run the following command:

   kubectl apply -f claim1.yaml
   

4. Create a cinder-test-rc.yaml file with the following content:

   apiVersion: v1
   kind: ReplicationController
   metadata:
     name: server
     labels:
       name: nginx
   spec:
     replicas: 1
     template:
       metadata:
         labels:
           name: nginx
       spec:
         containers:
         - name: server
           image: nginx
           volumeMounts:
             - mountPath: /var/lib/www/html
               name: cinderpvc
         volumes:
           - name: cinderpvc
             persistentVolumeClaim:
               claimName: claim1
   

5. Run the following command:

   kubectl apply -f cinder-test-rc.yaml
   

6. Verify that the volume was created:

   openstack volume list
   

7. Verify that Neutron LBaaS can create the LoadBalancer objects:

   1. Create an nginx-rs.yml file with the following content:

      apiVersion: extensions/v1beta1
      kind: ReplicaSet
      metadata:
        name: nginx
      spec:
        replicas: 4
        template:
          metadata:
            labels:
              app: nginx
          spec:
            containers:
              - name: nginx
                image: nginx:1.10
                resources:
                  requests:
                    cpu: 100m
                    memory: 100Mi
      

   2. Run the following commands:

      kubectl create -f nginx-rs.yml
      kubectl expose rs nginx --port 80 --type=LoadBalancer
      

8. Verify that the service has an external IP:

   kubectl get services -owide
   

   Example of system response:

   NAME       CLUSTER-IP    EXTERNAL-IP                  PORT(S)       AGE  SELECTOR
   kubernetes 10.254.0.1    <none>                       443/TCP       40m  <none>
   nginx      10.254.18.214 192.168.10.96,172.17.48.159  80:31710/TCP  1m   app=nginx
   

9. Verify that LoadBalancer was created in OpenStack:

   neutron lbaas-loadbalancer-list
   

   In the output, the vip_address should match the first external IP for the service created.
