title: Connect to service inside cluster
body: <p>I am reading "Kubernetes in Action" and trying samples from the book. I have created a pod:</p>
  
  <pre><code>apiVersion: v1
  kind: Pod
  metadata:
    name: kubia-manual
  spec:
    containers:
    - image: luksa/kubia
      name: kubia
      ports:
      - containerPort: 8080
        protocol: TCP
  </code></pre>
  
  <p>and service:</p>
  
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: kubia
  spec:
    ports:
    - port: 80
      targetPort: 8080
    selector:
      app: kubia
  </code></pre>
  
  <p>Here is my current state:</p>
  
  <pre><code># ~/work_folder/code/kubernetes/kubernetes-in-action/Chapter05 ±master » k get pods

  <p>Now I am trying to call the service from pod inside my cluster:</p>
  
  <pre><code># ~/work_folder/code/kubernetes/kubernetes-in-action/Chapter05 ±master » k exec kubia-manual -- curl -s 10.0.234.108               7 ↵

  <p>Why did I fail and how can I fix it ?</p>
