The Nautilus DevOps team is working on a Kubernetes template to deploy a web application on the cluster. There are some requirements to create/use persistent volumes to store the application code, and the template needs to be designed accordingly. Please find more details below:

  1. Create a PersistentVolume named as pv-devops. Configure the spec as storage class should be manual, set capacity to 4Gi, set access mode to ReadWriteOnce, volume type should be hostPath and set path to /mnt/itadmin (this directory is already created, you might not be able to access it directly, so you need not to worry about it).
  2. Create a PersistentVolumeClaim named as pvc-devops. Configure the spec as storage class should be manual, request 1Gi of the storage, set access mode to ReadWriteOnce.
  3. Create a pod named as pod-devops, mount the persistent volume you created with claim name pvc-devops at document root of the web server, the container within the pod should be named as container-devops using image nginx with latest tag only (remember to mention the tag i.e nginx:latest).
  4. Create a node port type service named web-devops using node port 30008 to expose the web server running within the pod.

Please paste YAML as code blocks so it does not lose formatting and indentation - like this

apiVersion: v1
kind: Service
metadata:
  name: web-devops
spec:
  type: NodePort
  selector:
    app: devops
  ports:
  - name: http
    port: 80
    targetPort: 80

The first thing I notice is that your service does not meet the requirement. You have not defined the required node port.
