<p>I am trying to install kubernetes cluster with vagrant and ansible and it does not work. 
As the error message, I've got: </p>

<pre><code>TASK [Configure node ip] *******************************************************

<p>What is wrong? Why the kubelet file can not be found?  </p>

softshipper
<p>The error occurs, because <code>/etc/default/kubelet</code> does not exist on the VMs. Add <code>create: yes</code> to the "Configure node ip" tasks in <code>master-playbook.yml</code> and <code>node-playbook.yml</code>, so that they look like this:</p>

<pre><code>  - name: Configure node ip
    lineinfile:
      path: /etc/default/kubelet
      line: KUBELET_EXTRA_ARGS=--node-ip={{ node_ip }}
      create: yes
</code></pre>

<p>This way, the file will be created if it does not exist.</p>
