Ingress example not working

[kimllee]

Hello,

The ingress example isn't working because now the api used is the networking v1 and the syntax doesn't seem to be recognized
Tested with GKE 1.21.5
Thank you.

The ingress example probably shouldn't be there at all as Ingress configuration is typically cluster-specific.

My adapted / working example on K3S 1.23

# hello-kubernetes-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: hello-kubernetes-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  rules:
  - http:
      paths:
      - pathType: Prefix #Exact
        backend:
          service:
             name: hello-kubernetes-hello-world
             port: 
              number: 80
        path: /hello-world(/|$)(.*)
      - pathType: Prefix #Exact   
        backend:
          service:
             name: hello-kubernetes-custom-message
             port: 
                number: 80
        path: /custom-message(/|$)(.*)
