reduce both the initial delay and the maximum delay accrued between container restarts for a node for containers in `CrashLoopBackOff` across the cluster to the recommended values of `1s` initial delay and `60s` maximum delay. To set this for a node, turn on the feature gate `ReduceDefaultCrashLoopBackOffDecay`. If you are also using the feature gate `KubeletCrashLoopBackOffMax` with a configured per-node `CrashLoopBackOff.MaxContainerRestartPeriod`, the effective kubelet configuration will follow the...
