  ContextA project thatyou are working on has a requirement for persistent data to be available.TaskTo facilitate this, perform the following tasks:* Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance* Create a PersistentVolume named task-pv- volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.* Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce* Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod Answer : see explanation below Explanation/Reference: Solution:

First, update the Deployment nginx-deployment in the prod namespace : . to run 2 replicas of the Pod . add the following label to the Pod : role: webFrontEnd Next, create a NodePort Service named rover in the prod namespace exposing the nginx-deployment Deployment 's Pods Answer : See the Explanation below for complete solution.

  Explanation/Reference: Below is anexam-style, step-by-step solution (commands + verification). Follow exactly on host ckad000. 0) Connect to the right host ssh ckad000 (Optional but good sanity check) kubectl config current-context kubectl get ns 1) Inspect the existing Deployment (to know its labels/ports) kubectl -n prod get deploy nginx-deployment kubectl -n prod get deploy nginx-deployment -o wide Check what labels the Pod template already has (important for the Service selector): kubectl -n prod get deploy nginx-deployment -o jsonpath='{.spec.template.metadata.labels}{"n"}' Check container ports (so we expose the correct targetPort): kubectl -n prod get deploy nginx-deployment -o jsonpath='{.spec.template.spec.containers[0].ports}{"n"}' If ports output is empty, it’s still often nginx on 80, but the safest is to confirm by describing a pod later. 2) Update Deployment to 2 replicas Fastest: kubectl -n prod scale deploy nginx-deployment --replicas=2 Verify: kubectl -n prod get deploy nginx-deployment 3) Add label role=webFrontEnd to the Pod (Pod template label) You must add it under: spec.template.metadata.labels Use a patch (quick + safe): kubectl -n prod patch deploy nginx-deployment

  -p '{"spec":{"template":{"metadata":{"labels":{"role":"webFrontEnd"}}}}}' Verify theDeployment template now includes it: kubectl -n prod get deploy nginx-deployment -o jsonpath='{.spec.template.metadata.labels}{"n"}' Now verify the running Pods have the label (important!): kubectl -n prod get pods --show-labels If the label doesn’t show on pods immediately, wait for rollout: kubectl -n prod rollout status deploy nginx-deployment kubectl -n prod get pods --show-labels 4) Create a NodePort Service rover exposing the Deployment’s Pods 4.1 Get a reliable target port Try to read containerPort: kubectl -n prod get deploy nginx-deployment -o jsonpath='{.spec.template.spec.containers[0].ports[0]. containerPort}{"n"}' If this prints a number (commonly 80), use it as --target-port. If it prints nothing/empty, check a pod: POD=$(kubectl -n prod get pod -l role=webFrontEnd -o jsonpath='{.items[0].metadata.name}') kubectl -n prod describe pod "$POD" | sed -n '/Containers:/,/Conditions:/p' | sed -n '/Ports:/,/Environment:/p' Assuming nginx is on 80 (most common), create the service: kubectl -n prod expose deploy nginx-deployment --name=rover --type=NodePort --port=80 --target-port=80 If your nginx container port is different (e.g., 8080), change --target-port=8080 accordingly. 5) Verify Service + endpoints (critical) kubectl -n prod get svc rover -o wide

Also confirm the pods are Ready: kubectl -n prod get pods -l role=webFrontEnd -o wide Quick “CKAD checkpoints” Deployment in prod has replicas=2 Pod template has label role=webFrontEnd Service rover in prod is NodePort Service endpoints point to the nginx pods
