<p>You may have had to enable a metrics-server. Heapster is now deprecated. Also make sure you have Kubernetes version greater than 1.7. You can check this buy typing <code>kubectl get nodes</code>.</p>

<p>You can enable the metrics server by looking at the minikube addons.</p>

<p><code>minikube addons list</code> gives you the list of addons.</p>

<p><code>minikube addons enable metrics-server</code> enables metrics-server.</p>

<p>Wait a few minutes, then if you type <code>kubectl get hpa</code> the percentage for the <code>TARGETS &lt;unknown&gt;</code> should appear.</p>
