When I try to setup traefik ingress controller on GKE, loadBalancer IP is not getting created on GCP to access the application externally though by looking on traefik dashboard, internal traefik IP is assigned successfully. Please find the traefik ingress YAML file for your reference:-

apiVersion: extensions/v1beta1
kind: Ingress

   kubernetes.io/ingress.class: traefik
   traefik.frontend.passHostHeader: "false"
   traefik.frontend.rule.type: PathPrefixStrip

poc/ingresses/cheese

      servicePort: http
    path: /stilton
  - backend:

    path: /cheddar
  - backend:
      serviceName: wensleydale
      servicePort: http
    path: /wensleydale
status:
   loadBalancer: {}

Can anyone help me on this if possible and let me know if you need any further details to debug this issue.
