Ingress with TLS: Secure External Access

Ingress without TLS is a security gap you cannot afford. Traffic entering your cluster travels unencrypted between client and ingress controller, exposing credentials, API tokens, and sensitive payloads to eavesdropping. The fix is straightforward: terminate TLS at the ingress controller.

The Kubernetes Ingress API is frozen. The project recommends Gateway API for new deployments. But the CKS exam still tests Ingress TLS configuration, and the vast majority of production clusters run Ingress today. You need to know both the mechanics and the security implications.
