An Ingress object has been applied successfully but no traffic is routed and its address stays empty. What should be checked first?

  1. Whether an Ingress controller is running in the cluster
  2. Whether the Service has a cluster IP
  3. Whether the Ingress is in the default namespace
  4. Whether the Ingress has a TLS section
Show the answer

Answer: A. Whether an Ingress controller is running in the cluster

Creating an Ingress resource has no effect on its own; some controller must be running and must claim that Ingress before anything is routed.
