Overview

Package service provides EndpointController implementation to manage and sync service endpoints.

CAUTION: If you update code in this file, you may need to also update code

in contrib/mesos/pkg/service/endpoints_controller.go

	// An annotation on the Service denoting if the endpoints controller should
	// go ahead and create endpoints for unready pods. This annotation is
	// currently only used by PetSets, where we need the pet to be DNS
	// resolvable during initialization. In this situation we create a headless
	// service just for the PetSet, and clients shouldn't be using this Service
	// for anything so unready endpoints don't matter.

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.Clientset) *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.
