Types ¶

type ReplicationManager ¶

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

ReplicationManager is responsible for synchronizing ReplicationController objects stored in the system with actual running pods. TODO: this really should be called ReplicationController. The only reason why it's a Manager is to distinguish this type from API object "ReplicationController". We should fix this.

func NewReplicationManager ¶

func NewReplicationManager(kubeClient client.Interface, resyncPeriod controller.ResyncPeriodFunc, burstReplicas int) *ReplicationManager

NewReplicationManager creates a new ReplicationManager.

func (*ReplicationManager) Run ¶

func (rm *ReplicationManager) Run(workers int, stopCh <-chan struct{})

Run begins watching and syncing.

func (*ReplicationManager) SetEventRecorder ¶

func (rm *ReplicationManager) SetEventRecorder(recorder record.EventRecorder)

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