	// go ahead and create endpoints for unready pods. This annotation is
	// currently only used by StatefulSets, where we need the pod to be DNS
	// resolvable during initialization and termination. In this situation we
	// create a headless Service just for the StatefulSet, and clients shouldn't
	// be using this Service for anything so unready endpoints don't matter.
	// Endpoints of these Services retain their DNS records and continue
	// receiving traffic for the Service from the moment the kubelet starts all
	// containers in the pod and marks it "Running", till the kubelet stops all
	// containers and deletes the pod from the apiserver.

Types

type EndpointController

type EndpointController struct {
	// contains filtered or unexported fields
}

EndpointController manages selector-based service endpoints.

func NewEndpointController

func NewEndpointController(podInformer cache.SharedIndexInformer, client clientset.Interface) *EndpointController

NewEndpointController returns a new *EndpointController.

func NewEndpointControllerFromClient

func NewEndpointControllerFromClient(client *clientset.Clientset, resyncPeriod controller.ResyncPeriodFunc) *EndpointController

NewEndpointControllerFromClient returns a new *EndpointController that runs its own informer.

func (*EndpointController) Run

func (e *EndpointController) Run(workers int, stopCh <-chan struct{})

Runs e; will not return until stopCh is closed. workers determines how many endpoints will be handled in parallel.
