Create a CTE-CSI protected Persistent Storage Claim by deploying an Application/Staging pod

To create a CTE-CSI protected Persistent Storage Claim by deploying an application pod:

1. Create the yaml file to deploy a pod and protect the contents of the Persistent Volume.

   apiVersion: v1
   kind: Pod
   metadata:
       name: cte-csi-demo
   spec:
     volumes:
       - name: test-vol
         persistentVolumeClaim:
           claimName: cte-test-claim1
     containers:
     - name: ubuntu
       image: ubuntu
       volumeMounts:
         - mountPath: "/data"
           name: test-vol
       command:
        - "sleep"
        - "604800"
       imagePullPolicy: IfNotPresent
     restartPolicy: Always
   

2. Deploy the pod, type:

   kubectl apply -f cte-csi-demo.yaml

   After the pod is successfully deployed and it running, you can see the client registered in K8s client.

   

3. To check the status of the pod, type:

   root@ip-172-30-1-55:~# kubectl get all

   NAME                                                READY   STATUS    RESTARTS        AGE
   pod/cte-csi-demo                                    1/1     Running   0               116m
   pod/cte-csi-user-demo                               1/1     Running   0               134m
   pod/cte-staging-pod9jhtn                            1/1     Running   0               133m
   pod/cte-staging-podt8jxs                            1/1     Running   0               116m
   
   NAME                                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
   service/kubernetes                     ClusterIP   10.96.0.1        <none>        443/TCP    224d
   

   After the pod is successfully deployed and running, you can see the clients registered in the Kubernetes client.

4. Login to the pod and check if the files are encrypted:

   root@ip-172-30-1-55:# kubectl exec -it cte-csi-demo /bin/bash

   kubectl exec [POD] -- [COMMAND]
   root@cte-csi-demo:/# cd /data/
   root@cte-csi-demo:/data# mkdir sub_dir
   root@cte-csi-demo:/data# cd sub_dir/
   root@cte-csi-demo:/data/sub_dir# echo "testfile" >> test
   root@cte-csi-demo:/data/sub_dir#
   root@cte-csi-demo:/data/sub_dir# cat test
   testfile
   

5. Check the same file on the Server side:

   root@aws-thales-dockerregistry:~# cd /nfs-share/sub_dir/
   root@aws-thales-dockerregistry:/nfs-share/sub_dir# ls -l
   total 8
   -rw-r--r-- 1 root root 4102 Dec 13 20:04 test
   root@aws-thales-dockerregistry:/nfs-share/sub_dir# cat test
