Error when creating Kubernetes Ingress resource (no matches for kind "Ingress")

Question

In a cluster kubernetes environment I have Traefik v3.2.1 and CertManager 1.16.1 and a program I am testing. when I try to apply this file: 022-red-ing.yml I get this error:

error: error validating "022-red-ing.yml": error validating data: [apiVersion not set, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false

I would like to define the file correctly but I am missing information since the documentation from where I copied it did not stated the apiVersion and kind.

The file is currently like this:

cat 022-red-ing.yml

   apiVersion: networking.k8s.io/v1
    kind: Ingress
    spec:
      selector:
        istio: ingressgateway
      servers:
      - hosts:
        - program.example.domain
        port:
          name: https
          number: 443
          protocol: HTTPS
        tls:
          credentialName: tls-program-ingress-http
          mode: SIMPLE
      - hosts:
        - program.example.domain
        port:
          name: program-frontend
          number: 80
          protocol: HTTP
        tls:
          httpsRedirect: true
      - hosts:
        - '*'
        port:
          name: http
          number: 80
          protocol: HTTP

what apiVersion and kind should I set? If I prepend this code:

apiVersion: extensions/v1beta1
kind: Ingress

I get another error. right now when I do:

kubectl apply -f 022-red-ing.yml

I get

error: error when retrieving current configuration of:
Resource: "networking.k8s.io/v1, Resource=ingresses", GroupVersionKind: "networking.k8s.io/v1, Kind=Ingress"
Name: "", Namespace: "default"
from server for: "022-red-ing.yml": resource name may not be empty

I'm doing something wrong.

The file is currently like this...

I'm almost positive that it is not, because that file is not a valid Kubernetes manifest (it's missing the apiVersion, kind, and metadata sections).

From the error message (No matches for kind "Ingress" in version "extensions/v1beta1"), it looks like you're using the incorrect apiVersion in the manifest. Instead of:

apiVersion: extensions/v1beta1

You need:

apiVersion: networking.k8s.io/v1

This is straight from the official documentation; it's not clear why you're using the wrong value, but it suggests you may be reading outdated material.
