Ingress resource vs Ingress controller
Source: interviewadvanced
WHAT IT TESTS: Separating config from the engine. OUTLINE: The Ingress resource is declarative routing rules; the controller is the running proxy (NGINX, etc.) that reads them and serves traffic.
WHAT IT TESTS: Whether you distinguish desired-state config from the component that enforces it. ANSWER OUTLINE: An Ingress resource is a declarative API object holding host and path routing rules and TLS config; it does nothing by itself. An Ingress controller is a running workload (NGINX, Traefik, cloud controller) that watches Ingress resources and configures itself to proxy traffic accordingly.
