Container Immutability Lab

This hands-on lab teaches you to enforce container immutability in Kubernetes.

You'll learn to:

• Understand immutability principles and their security benefits
• Configure read-only root filesystems for containers
• Use emptyDir volumes for temporary writable storage
• Implement security contexts to enforce immutability
• Test and validate immutable container configurations

Container immutability prevents attackers from modifying container filesystems, reducing the attack surface and preventing persistence. This is a key CKS exam topic.
