A developer creates a valid Ingress object for a clinic booking UI, but no external HTTP routing appears. Cluster admins confirm no Ingress controller is running. What does that imply for the developer?
Select an answer to reveal the explanation.
Short Explanation
An Ingress YAML is a work order, not the worker. Without a controller (NGINX, Traefik, cloud LB controller, and so on) watching the API, nothing programs the actual HTTP routers. Creating the object alone does not light up the path.
Full Explanation
Ingress is an API object; implementation is provided by a separate Ingress controller that watches Ingresses and configures a proxy or load balancer. Absent a controller, rules remain inert. There is no universal built-in Ingress data plane activated solely by the resource, and ConfigMaps or ClusterIP Services do not substitute for a controller.
