Question 12/86

You have a web application that uses two different services: 'frontend' and 'backend'. You want to restrict access to the 'backend' service from all pods except those with the label 'app: frontend'. How would you configure NetworkPolicy to achieve this?

Correct Answer:

See the solution below with Step by Step Explanation.
Explanation:

- Replace with your actual namespace. 2. Apply the NetworkPolicy: - Run the following command to apply the NetworkPolicy: bash kubectl apply -f backend-networkpolicy.yaml - This NetworkPolicy defines a policy for pods with the label 'app: backend'. - The 'ingress' rule allows traffic only from pods with the label 'app: frontend'. - All other pods will be blocked from accessing the 'backend' service. This ensures that only the frontend' service can communicate with the 'backend' service. ,
