Services. Ingress. ConfigMaps. Secrets. HPA. They memorize them without understanding why they exist. Every concept in Kubernetes exists because something broke. Someone ran it in production, something failed, and a new concept was born to fix it. Let me show you the full story in order. You start with a Pod. A pod runs your container. Simple. Clean. Done.
