Feature gates are a set of key=value pairs that describe features. You can turn these features on or off using the --feature-gates=foo=true,bar=false command line flag on each component.
var foo = feature.MustRegister("Foo", false,
feature.WithFeatureStage(feature.StageAlpha),
feature.WithFeatureFromVersion("0.0.1"),
feature.WithFeatureToVersion("1.0.0"),
feature.WithFeatureDescription("A foo feature"),
)
if foo.Enabled() {
// TODO Feature
}
