<p>I create cluster on <code>Google Kubernetes Engine</code> with <code>Cluster Autoscaler</code> option  enabled.<br>
I want to config the scaling behavior such as <code>--scale-down-delay-after-delete</code> according to <a href="https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md" rel="noreferrer">https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md</a> .</p>

<p>But I found no Pod or Deployment on kube-system which is cluster autoscaler.</p>

<p>Anyone has ideas?</p>

<hr>

<p>Edit: 
I am <strong>not</strong> saying <code>Horizontal Pod Autoscaler</code>.</p>

<p>And I hope I can configure it as like this :</p>

<pre><code>$ gcloud container clusters update cluster-1 --enable-autoscaling --scan-interval=5 --scale-down-unneeded-time=3m
ERROR: (gcloud.container.clusters.update) unrecognized arguments:
  --scan-interval=5
  --scale-down-unneeded-time=3m
</code></pre>

<p>It is not possible according to <a href="https://github.com/kubernetes/autoscaler/issues/966" rel="nofollow noreferrer">https://github.com/kubernetes/autoscaler/issues/966</a></p>

<p>Probably because there is no way to access the executable (which it seems to be) on GKE.</p>

<p>You can't even view the logs of the autoscaler on GKE: <a href="https://github.com/kubernetes/autoscaler/issues/972" rel="nofollow noreferrer">https://github.com/kubernetes/autoscaler/issues/972</a></p>
