i have setup a kubernetes cluster with 3 masters and multiple workers (kubeadm)
if i shut down a worker the node goes into Not-ready state fairly quickly but it takes some time for pods assigned to that node to be rescheduled
how can i decrease the timeout values to make my cluster react faster?


Unfortunately, there is no way to make it faster. A lot of actions are supposed to be done by Kubernetes to restart pods from a failed node. However, it is possible to enhance reaction time.

For example, reduce the value of node-monitor-grace-period, default is 40 seconds. It can decrease time between actual fail of a node and changing of its status.
