CKA Practice Question #23: Implementing NetworkPolicy for Secure Cluster Communication

Kubernetes Network Policy, CKA Exam Prep, Kubernetes Security

Learn how to secure your Kubernetes cluster with Network Policies! In this walkthrough, we'll tackle CKA (Certified Kubernetes Administrator) practice question #23. You'll discover how to create a NetworkPolicy (np-backend) in the project-snake namespace, restricting communication from backend-* pods to only db1-* and db2-* pods on port 80.

This video covers:
- Kubernetes Network Policies
- Pod-to-Pod communication control
- Label selectors (app label)
- Restricting cluster access
- CKA exam preparation

Follow along as we demonstrate:
- Creating a NetworkPolicy YAML file
- Applying the policy to the cluster
- Verifying policy enforcement

Enhance your Kubernetes security skills and prepare for the CKA exam with this hands-on tutorial.
