how to update kubelet and controller manager parameters in gke

Question

I want to update the following parameters in kubelet and controller manager in gke for reducing node fault detection time.

kubelet: node-status-update-frequency controller-manager: node-monitor-period controller-manager: node-monitor-grace-period controller-manager: pod-eviction-timeout

Can anyone please let me know how to update these parameters in gke?

Thanks.

It is not possible to update those parameters on GKE. Generally speaking, it's not advisable to update these settings as there are potential side effects if many pods start to fail at the same time, especially as you increase the number of nodes. GKE sets sane defaults for these parameters.
