# Feature Gates

Feature GatesThis page contains an overview of the various feature gates an administrator can specify on different Kubernetes components.See feature stages for an explanation of the stages for a feature.OverviewFeature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component.Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component. Use -h flag to see a full set of feature gates for all components. To set feature gates for a component, such as kubelet, use the --feature-gates flag assigned to a list of feature pairs:--feature-gates=...,GracefulNodeShutdown=true The following tables are a summary of the feature gates that you can set on different Kubernetes components.The "Since" column contains the Kubernetes release when a feature is introduced or its release stage is changed.The "Until" column, if not empty, contains the last Kubernetes release in which you can still use a feature gate.If a feature is in the Alpha or Beta state, you can find the feature listed in the Alpha/Beta feature gate table.If a feature is stable you can find all stages for that feature listed in the Graduated/Deprecated feature gate table.The Graduated/Deprecated feature gate table also lists deprecated and withdrawn features.Note:For a reference to old feature gates that are removed, please refer to feature gates removed.Feature gates for Alpha or Beta featuresFeature gates for features

a featureFeature stagesA feature can be in Alpha, Beta or GA stage. An Alpha feature means:Disabled by default.Might be buggy. Enabling the feature may expose bugs.Support for feature may be dropped at any time without notice.The API may change in incompatible ways in a later software release without notice.Recommended for use only in short-lived testing clusters, due to increased risk of bugs and lack of long-term support.A Beta feature means:Usually enabled by default. Beta API groups are disabled by default.The feature is well tested. Enabling the feature is considered safe.Support for the overall feature will not be dropped, though details may change.The schema and/or semantics of objects may change in incompatible ways in a subsequent beta or stable release. When this happens, we will provide instructions for migrating to the next version. This may require deleting, editing, and re-creating API objects. The editing process may require some thought. This may require downtime for applications that rely on the feature.Recommended for only non-business-critical uses because of potential for incompatible changes in subsequent releases. If you have multiple clusters that can be upgraded independently, you may be able to relax this restriction.Note:Please do try Beta features and give
