HAProxy Kubernetes Ingress Controller Documentation 1.4

View metrics

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, which you can see by listing the service’s details.

$ kubectl get services --namespace haproxy-controller

output

NAME                         TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)                                     AGE
haproxy-kubernetes-ingress   NodePort   10.96.15.205    <none>        80:30279/TCP,443:30775/TCP,1024:31912/TCP   84s

In this example, port 1024 is mapped to NodePort 31912.
