Security and production readiness

Secure clusters and run them in production.

📖 Key ideas

  1. RBAC controls who can do what in the cluster.
  2. Run containers as non-root with minimal images.
  3. Scan images for vulnerabilities; sign them.
  4. Namespaces separate teams and environments.
  5. Certifications: CKAD, CKA, CKS.
💡 Real-life example: Namespaces are separate floors in an office; RBAC is the keycard deciding floor access.
