Once done, click on the Next Question button in the top right corner of this panel. You may navigate back and forth freely between all questions. Once done with all questions, click on End Exam. Your work will be validated at the end and score shown. Good Luck!

kubectl run --generator=run-pod/v1 nginx-pod --image=nginx:alpine
  1. Deploy a messaging pod using the redis:alpine image with the labels set to tier=msg.
kubectl run --generator=run-pod/v1 --image redis:alpine --labels=tier=msg messaging
  1. Create a namespace named apx-x9984574
kubectl create ns apx-x9984574
  1. Get the list of nodes in JSON format and store it in a file at /opt/outputs/nodes-z3444kd9.json
kubectl get nodes -o json > /opt/outputs/nodes-z3444kd9.json
  1. Create a service messaging-service to expose the messaging application within the cluster on port 6379. Use imperative commands

kubectl expose pod messaging --name=messaging-service --port 6379

  1. Create a deployment named hr-web-app using the image kodekloud/webapp-color with 2 replicas
kubectl run hr-web-app --image kodekloud/webapp-color --replicas=2
  1. Create a static pod named static-busybox that uses the busybox image and the command sleep 1000
kubectl run --generator=run-pod/v1 static-busybox --image busybox --command "sleep 1000" --dry-run -o yaml > /etc/kubernetes/manifests/static-busybox.yaml

  1. A new application orange is deployed. There is something wrong with it. Identify and fix the issue.

Wrong command in init container.

  1. Expose the hr-web-app as service hr-web-app-service application on port 30082 on the nodes on the cluster The web application listens on port 8080
kubectl expose deploy hr-web-app --name=hr-web-app-service --port 8080 --target-port 8080 --type NodePort --dry-run -o yaml > service.yaml

Edit the service and add the field nodePort: 30082

  1. Use JSON PATH query to retrieve the osImages of all the nodes and store it in a file /opt/outputs/nodes_os_x43kj56.txt

The osImages are under the nodeInfo section under status of each node.

kubectl get nodes -o=jsonpath='{.items[*].status.nodeInfo.osImage}' > /opt/outputs/nodes_os_x43kj56.txt
