I also see:
kubectl apply -f ingress.yaml
error: unable to recognize "ingress.yaml": no matches for kind "Ingress" in version "extensions/v1beta1"

Thanks, I'll check the all lab with new K8s version

I could keep following the demo with this version of the ingress.yaml file:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: guestbook-ingress
spec:
  rules:
  - host: frontend.minikube.local
    http:
      paths:
      - path: /
        pathType: ImplementationSpecific
        backend:
          service:
            name: "frontend"
            port:
              number: 80
  - host: backend.minikube.local
    http:
      paths:
      - path: /
        pathType: ImplementationSpecific
        backend:
          service:
            name: "backend"
            port:
              number: 80

Hello, I plan to do an update of the Labs for latest k8s version in the next weeks. In the meanwhile it is only supposed to work with the version used in the course unfortunately.

Recommend to use Kind with Ingress in Mac system.
https://kind.sigs.k8s.io/docs/user/ingress/
It will fix the problem that can't access host through local web browser. And don't forget to add DNS in /etc/hosts.
