The ingress controller exposes the HAProxy Stats page and a Prometheus endpoint on port 1024. When deploying the ingress controller with a NodePort service, this port will be mapped to a random, high-numbered port. Get the NodePort value by listing the service’s details:

nix
kubectl get services --namespace haproxy-controller
nix
kubectl get services --namespace haproxy-controller

The details show that the port is 31912:
