<p>I have  horizontal pod autoscaler running on GKE. It works but its slow to respond to increases in workload, so I would like to try modifying a couple of the kube-controller-manager parameters, specifically:</p>

<p>--horizontal-pod-autoscaler-upscale-delay
--horizontal-pod-autoscaler-downscale-delay</p>

<p>But the only CLI available seems to be kubectl. I have scoured docs and the client API but can find no way to do it, in fact this link suggested it may not be possible on GKE:</p>

<p><a href="https://stackoverflow.com/questions/46317275/change-the-horizontal-pod-autoscaler-sync-period-with-gke">change the horizontal-pod-autoscaler-sync-period with gke</a></p>

<p>Does anyone know if there is a way to do it?</p>

<p>Thank you!</p>

<p>These flags must be configured in the kube-controller-manager and since you cannot pass flags to the GKE cluster it is impossible to modify the autoscaler settings on GKE.</p>
