Lab1 Does Ingress Does Not Work With Later Versions of K8s

[NiallJude]

Starting in version 1.19, K8s dropped support for extenstions/v1beta1 Ingress and now, you must use networking.k8s.io/v1 but there are also some changes to fields + variables which are necessary to update the ingress.yaml. Do you have a version available which is compatible? I would prefer not to rollback my k8s version.

Error:

kubectl apply -f ../../lab1_kubectl_version1/yaml/ingress.yaml
error: unable to recognize "../../lab1_kubectl_version1/yaml/ingress.yaml": no matches for kind "Ingress" in version "extensions/v1beta1"

I think it's something like this now but it's not exactly correct:

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

Hello, yes indeed, if you use recent K8s versions, you have to change the apiVersion from extension/v1beta to 'apiVersion: networking.k8s.io/v1'

Will be updated with the next PluralSight helm course release
