<p>I have configured one Ubuntu system (192.168.1.2) to be a master and minion.</p>

<p>Another Ubuntu machine to be a minion (192.168.1.3). I performed upgrade on Ubuntu machine that was both master and minion and rebooted the system. </p>

<p>Now when I perform:</p>

<p><code>kubectl get nodes</code></p>

<p>The node (192.168.1.2) is down. </p>

<p>I went through the documentation but could not find any documentation that explains how to add back the lost nodes. </p>

<p>I need some help to understand how to bring the node back into the Kubernetes cluster. Is there any script to do so?</p>

<p>Thanks</p>

<p>I am not aware of any script, but here are a few basic things might help:</p>

<ol>
<li>Please ensure that <code>kubelet</code> and <code>docker</code> services are running on the node in question.</li>
<li>Run <code>kubectl describe node &lt;nodename&gt;</code> to get additional details.</li>
<li>Get the logs of <code>kubelet</code> service if it is already running by executing <code>journalctl -u kubelet</code></li>
</ol>
