Error with Traefik on Google Kubernetes Engine

I'm trying to deploy Traefik as an ingress controller on my GKE cluster. It's a basic cluster with 3 nodes.

I'm used to deploy Traefik using manifest on a Kubernetes cluster deployed by Kubespray, but we are migrating some of our infrastructures to GCP.

So I tried to deploy Traefik using the community helm chart with the following configuration:

image: traefik
imageTag: 1.6.2

serviceType: LoadBalancer
loadBalancerIP: X.X.X.X

  ingressClass: traefik

  enabled: false
  enforced: false
  insecureSkipVerify: false

  enabled: false
  staging: true
  logging: false
  challengeType: http-01

  enabled: true
    annotations: traefik

  enabled: true
  enabled: true
  format: common 

And then launch it with the following command:

helm install --namespace kube-system --name traefik --values values.yaml stable/traefik

All is well deployed on my K8S cluster, except the dashboard-ingress with the following error:

  Warning  Sync    4m    loadbalancer-controller  googleapi: Error 400: Invalid value for field 'namedPorts[2].port': '0'. Must be greater than or equal to 1, invalid

Any idea where is my error?

Thanks a lot!

Invalid value for field 'namedPorts[0].port': '0'

This error happens when the Service that's being used by GKE Ingress is of type ClusterIP (and not NodePort). GKE Ingress requires backing Services to be of type NodePort.

Setting up HTTP(S) Load Balancing with Ingress, Invalid value for field 'namedPorts[0].port': '0'. This error happens when the Service that's being used by GKE Ingress is of type ClusterIP (and not NodePort ). Google Kubernetes Engine is a great and easy way to explore Kubernetes without having to worry about creating a cluster on your own. While playing around with it, I immediately started asking

This can also happen when the service that the ingress controller expects does not exists. (maybe it was accidentally deleted)

nginx-ingress-controller on gke works with services exposed as clusterIP

  • Hi traefik-dashboard:80 ( Why is there two different Port?
  • Hey thanks for your answer! Yes I think this is related to the traefik dashboard handle by the GKE ingress. But this is weird because I tried to specify the ingress class with the following annotation: traefik Any idea on why the ingress is ignoring the annotation?
  • Traefik should definitely respect that annotation (and GKE's Ingress controller should definitely ignore such Ingresses then). Could you please share your dashboard's Ingress spec (in case this is still relevant to you)?
