- Change the feature gate from alpha to beta and enable it by default - Update a few of the unit tests due to feature gate being enabled by default - Small refactor in `nodeshutdown_manager` which adds `featureEnabled` function (which checks that feature gate and that `kubeletConfig.ShutdownGracePeriod > 0`). - Use `featureEnabled()` to exit early from shutdown manager in the case that the feature is disabled - Update kubelet config defaulting to be explicit that `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods` default to zero and update the godoc comments. - Update defaults and add featureGate tag in api config godoc. With this feature now in beta and the feature gate enabled by default, to enable graceful shutdown all that will be required is to configure `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods` in the kubelet config. If not configured, they will be defaulted to zero, and graceful shutdown will effectively be disabled. Kubernetes-commit: 893f5fd4f007775d48536cae192d79f209eeeac2 |
