A county creates several Ingress objects for internal tools, but none of the hostnames respond. What prerequisite is most likely missing?
Select an answer to reveal the explanation.
Short Explanation
Ingress manifests without a controller are like traffic signs with no traffic lights installed. You need a live Ingress controller to watch those objects and actually route requests.
Full Explanation
Ingress resources are declarative; they take effect only when an Ingress controller is running and configured to claim them (often via IngressClass). Without that controller, host rules sit unused. StorageClass naming, deleting ClusterIPs, or changing restartPolicy does not enact Ingress routing.
