kubernetesクラスタのノード間にレイテンシの制限はありません。これらは設定可能なパラメータです。
ワーカーノード上のkubeletにとっては、次のとおりです。
--node-status-update-frequency duration Specifies how often kubelet posts node status to master. Note: be cautious when changing the constant, it must work with nodeMonitorGracePeriod in nodecontroller. (default 10s)
は、マスターノード上のcontroller-managerために、それらは以下のとおりです。
--node-monitor-grace-period duration Amount of time which we allow running Node to be unresponsive before marking it unhealthy. Must be N times more than kubelet's nodeStatusUpdateFrequency, where N means number of retries allowed for kubelet to post node status. (default 40s)
--node-monitor-period duration The period for syncing NodeStatus in NodeController. (default 5s)
--node-startup-grace-period duration Amount of time which we allow starting Node to be unresponsive before marking it unhealthy. (default 1m0s)
