Functions

func New

func New(

	SetDrainedNotification(<-chan struct{})
	admission.InitializationValidator

	SetExternalKubeClientSet(kubernetes.Interface)
	admission.InitializationValidator
}

WantsExternalKubeClientSet defines a function which sets external ClientSet for admission plugins that need it

type WantsExternalKubeInformerFactory

type WantsExternalKubeInformerFactory interface {
	SetExternalKubeInformerFactory(informers.SharedInformerFactory)
	admission.InitializationValidator
}

WantsExternalKubeInformerFactory defines a function which sets InformerFactory for admission plugins that need it

type WantsFeatures

type WantsFeatures interface {
	InspectFeatureGates(featuregate.FeatureGate)
	admission.InitializationValidator
}

WantsFeatureGate defines a function which passes the featureGates for inspection by an admission plugin. Admission plugins should not hold a reference to the featureGates. Instead, they should query a particular one and assign it to a simple bool in the admission plugin struct.

func (a *admissionPlugin) InspectFeatureGates(features featuregate.FeatureGate){
    a.myFeatureIsOn = features.Enabled("my-feature")
}

type WantsQuotaConfiguration

type WantsQuotaConfiguration interface {
	SetQuotaConfiguration(quota.Configuration)
	admission.InitializationValidator
}
