Hi There,
I have a question regarding ingress resources, How does an ingress resource find the ingress controller service despite of not using labels/selectors on the ingress resource?
Regards
Hi,
Ingress resources use the kubernetes.io/ingress.class annotation to match with the correct ingress controller.
The kubernetes.io/ingress.class annotation is not being preferred or suggested to use as it can be deprecated in future. Better to use the field ingress.spec.ingressClassName . But, when user has deployed with scope.enabled , then the ingress class resource field is not used.
