Enhancement suggestions / feature requests

Can we update the Traefik nodeport chart to not use host port 9100 for it's metrics? This clashes with the kube-prometheus stack's node-exporter which also uses host port 9100.

As Traefik is a default marketplace option it'd be good to get this changed so people can install kube-prometheus straight onto their clusters.

k get ds traefik -o json | jq -r '.spec.template.spec.containers[0].ports[0]'
{
  "containerPort": 9100,
  "hostPort": 9100,
  "name": "metrics",
  "protocol": "TCP"
}

@jakeloxton - can you suggest the change required here?

ports.metrics.port is the key to change.

It's actually mentioned in the official Helm chart
