Creating Persistent Storage for Pods in Kubernetes

Pods in Kubernetes are ephemeral, which makes the local container filesytem unusable, as you can never ensure the pod will remain. To decouple your storage from your pods, you will be creating a persistent volume to mount for use by your pods. You will be deploying a redis image. You will first create the persistent volume, then create the pod YAML for deploying the pod to mount the volume. You will then delete the pod and create a new pod, which will access that same volume.

  1. Challenge

    Create a PersistentVolume.

    1. Use the following YAML spec for the PersistentVolume named redis-pv.yaml:

      apiVersion: v1
      kind: PersistentVolume
        name: redis-pv
        storageClassName: ""
          storage: 1Gi
          - ReadWriteOnce
          path: "/mnt/data"
    2. Then, create the PersistentVolume:

      kubectl apply -f redis-pv.yaml
  2. Challenge

    Create a PersistentVolumeClaim.

    1. Use the following YAML spec for the PersistentVolumeClaim named redis-pvc.yaml:

      apiVersion: v1
      kind: PersistentVolumeClaim
        name: redisdb-pvc
        storageClassName: ""
          - ReadWriteOnce
            storage: 1Gi
    2. Then, create the PersistentVolumeClaim:

      kubectl apply -f redis-pvc.yaml
  3. Challenge

    Create the redispod image, with a mounted volume to mount path `/data`

    1. Use the following YAML spec for the pod named redispod.yaml:

      apiVersion: v1
      kind: Pod
        name: redispod
        - image: redis
          name: redisdb
          - name: redis-data
            mountPath: /data
          - containerPort: 6379
            protocol: TCP
        - name: redis-data
            claimName: redisdb-pvc
    2. Then, create the pod:

      kubectl apply -f redispod.yaml
    3. Verify the pod was created:

      kubectl get pods
  4. Challenge

    Connect to the container and write some data.

    1. Connect to the container and run the redis-cli:

      kubectl exec -it redispod redis-cli
    2. Set the key space server:name and value "redis server":

      SET server:name "redis server"
    3. Run the GET command to verify the value was set:

      GET server:name
    4. Exit the redis-cli:

  5. Challenge

    Delete `redispod` and create a new pod named `redispod2`.

    1. Delete the existing redispod:

      kubectl delete pod redispod
    2. Open the file redispod.yaml and change line 4 from name: redispod to:

      name: redispod2
    3. Create a new pod named redispod2:

      kubectl apply -f redispod.yaml
  6. Challenge

    Verify the volume has persistent data.

    1. Connect to the container and run redis-cli:

      kubectl exec -it redispod2 redis-cli
    2. Run the GET command to retrieve the data written previously:

      GET server:name
    3. Exit the redis-cli:
