Access your services inside the cluster

If you are using Linux you should follow this fantastic tutorial from @mauilion

https://mauilion.dev/posts/kind-metallb/

If you are using Windows or Mac you have to deal with the problems of the docker limitations on those platforms

There are different alternatives, one is using the HostPort feature to expose Pods ports, but has the limitation that you have to know in advance which node will host the Pod.

An example can be:

kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 80
    hostPort: 80

and deploying the service using HostPort to expose the port:

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-httpd
spec:
  selector:
    matchLabels:
      run: my-httpd
  replicas: 1
  template:
    metadata:
      labels:
        run: my-httpd
    spec:
      containers:
      - name: httpd
        image: httpd:2-alpine
        ports:
        - containerPort: 80
          hostPort: 80---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-httpd
spec:
  selector:
    matchLabels:
      run: my-httpd
  replicas: 1
  template:
    metadata:
      labels:
        run: my-httpd
    spec:
      containers:
      - name: httpd
        image: httpd:2-alpine
        ports:
        - containerPort: 80
          hostPort: 80

Instead of exposing the POD port directly, you can go with more advanced alternatives like Contour
