Feature Gates

This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components.


Feature gates are a set of key=value pairs that describe alpha or experimental features. An administrator can use the --feature-gates command line flag on each component to turn a feature on or off. The following table is a summary of the feature gates that you can set on different Kubernetes components.

Using a Feature

Feature Stages

A feature can be in Alpha, Beta or GA stage. An Alpha feature means:

A Beta feature means:

Note: Please do try Beta features and give feedback on them! After they exit beta, it may not be practical for us to make more changes.

A GA feature is also referred to as a stable feature. It means:

Feature Gates

Each feature gate is designed for enabling/disabling a specific feature:
