title: Enable Ingress controller on Docker Desktop with WLS2
body: <p>Currently, I'm using Docker Desktop with <strong>WSL2</strong> integration. I found that <strong>Docker Desktop</strong> automatically had created a cluster for me. It means I don't have to install and use <strong>Minikube</strong> or <strong>Kind</strong> to create cluster.
  The problem is that, how could I enable <strong>Ingress Controller</strong> if I use &quot;built-in&quot; cluster from Docker Desktop?
  I tried to create an <strong>Ingress</strong> to check if this work or not, but as my guess, it didn't work.</p>
  <p>The YAML file I created as follows:</p>
  <pre><code>apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: webapp
  spec:
    minReadySeconds: 30
    selector:
      matchLabels:
        app: webapp
    replicas: 1
    template:
      metadata:
        labels:
          app: webapp
      spec:
        containers:
        - name: webapp
          image: nodejs-helloworld:v1
  
  --- 
  
  apiVersion: v1
  kind: Service
  metadata:
    name: webapp-service
  
  spec:
    selector: 
      app: webapp
    
    ports:
      - name: http
        port: 3000
        nodePort: 30090 # only for NotPort &gt; 30,000
      
    type: NodePort #ClusterIP inside cluster
  
  ---
  
  apiVersion: networking.k8s.io/v1
  kind: Ingress 
  metadata:
    name: webapp-ingress
  spec:
    defaultBackend:
      service:
        name: webapp-service
        port:
          number: 3000
    rules:
    - host: ingress.local
      http:
        paths:
        - path: / 
          pathType: Prefix
          backend:
            service:
              name:  webapp-service
              port: 
                number: 3000
      
  </code></pre>
  <p>I tried to access <em>ingress.local/</em> but it was not successful. (I added ingress.local to point to 127.0.0.1 in host file. And the <strong>webapp</strong> worked fine at <em>kubernetes.docker.internal:30090</em> )</p>
  <p>Could you please help me to know the root cause?
  Thank you.</p>
