How do I get a single Ingress to be handled by just one of two HAProxy Ingress Controllers on AKS?
This issue is due to a bug in https://github.com/haproxytech/kubernetes-ingress when using IngressClassName in ingress.yaml. If you remove IngressClassName from your ingress.yaml and just use "kubernetes.io/ingress.class": annotation the issue goes away, it more of a workaround than a fix.
This issue has been raised and still open see link below for updates.
