问题
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:
--horizontal-pod-autoscaler-upscale-delay --horizontal-pod-autoscaler-downscale-delay
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:
change the horizontal-pod-autoscaler-sync-period with gke
Does anyone know if there is a way to do it?
Thank you!
回答1:
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.
