Types

type ReplicaSetController

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

ReplicaSetController is responsible for synchronizing ReplicaSet objects stored in the system with actual running pods.

func NewReplicaSetController

func NewReplicaSetController(kubeClient clientset.Interface, resyncPeriod controller.ResyncPeriodFunc, burstReplicas int, lookupCacheSize int) *ReplicaSetController

NewReplicaSetController creates a new ReplicaSetController.

func (*ReplicaSetController) Run

func (rsc *ReplicaSetController) Run(workers int, stopCh <-chan struct{})

Run begins watching and syncing.

func (*ReplicaSetController) SetEventRecorder

func (rsc *ReplicaSetController) SetEventRecorder(recorder record.EventRecorder)

SetEventRecorder replaces the event recorder used by the ReplicaSetController with the given recorder. Only used for testing.
