<p>Because docker supports out of the box kubernetes (on my Mac) I thought I try it out and see if I can load balance a simple webservice. For that, I created a simple image, which exposes port 3000 and only returns <code>Hello World</code>. And I created a k8s config yaml</p>

<pre><code>apiVersion: v1
kind: Service
metadata:
  name: hello-kubernetes
spec:
  type: NodePort
  externalIPs:
  - 192.168.2.85
ports:
  - port: 8080
    targetPort: 3000
selector:
  app: hello-kubernetes
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-kubernetes
spec:
  replicas: 3
  selector:
    matchLabels:
      app: hello-kubernetes
  template:
    metadata:
      labels:
        app: hello-kubernetes
    spec:
      containers:
        - name: hello-kubernetes
          image: hello/world:latest
          ports:
            - containerPort: 3000
</code></pre>

<p>Apply it</p>

<pre><code>$&gt; kubectl apply -f ./example.yaml
</code></pre>

<p>I see 3 pods running, and a service</p>

<pre><code>NAME               TYPE        CLUSTER-IP      EXTERNAL-IP    PORT(S)          AGE
hello-kubernetes   NodePort    10.99.38.46     192.168.2.85   8080:30244/TCP   42m
</code></pre>

<p>I've used NodePort above, but I'm not sure if I can use <code>Loadbalancer</code> here as well.</p>

<p>Anyway, in the browser I get the message <code>This site can’t be reached</code> when I goto <code>http://192.168.2.85:8080</code> or `<a href="http://192.168.2.85:30244" rel="nofollow noreferrer">http://192.168.2.85:30244</a> (I never know which port to use)</p>

<p>So, I think I'm close, but I still missed something :( Any help would be appreciated!</p>

<p>the port number is wrong.</p>

<p>use <a href="http://NODEIP:NODEPORT" rel="nofollow noreferrer">http://NODEIP:NODEPORT</a></p>

<p>in your case, try</p>

<p><a href="http://NODEIP:30244" rel="nofollow noreferrer">http://NODEIP:30244</a></p>
