I'm following the http load balancing tutorial for creating an Ingress resource for load balancing.

As seen in the tutorial, the Ingress config file looks like this:

apiVersion: extensions/v1beta2
kind: Ingress
metadata:
  name: basic-ingress
spec:
  backend:
    serviceName: nginx
    servicePort: 80

But once I try to create the resource, I always get back this error:

Error from server (BadRequest): error when creating "basic-ingress.yaml": Ingress in version "v1beta2" cannot be handled as a Ingress: no kind "Ingress" is registered for version "extensions/v1beta2"

In the past, I saw similar errors when a value wasn't in the right type (number instead of string), but now that doesn't seem the case.

I tried in both 1.7.8-gke.0 (default) and 1.8.1-gke.1 (latest) versions.

Any help would be really much appreciated.

Cheers
