Types

type QueueingEventHandler

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

QueueingEventHandler queues the key for the object on add and update events

func (*QueueingEventHandler) OnAdd

func (h *QueueingEventHandler) OnAdd(obj interface{})

func (*QueueingEventHandler) OnDelete

func (h *QueueingEventHandler) OnDelete(obj interface{})

func (*QueueingEventHandler) OnUpdate

func (h *QueueingEventHandler) OnUpdate(oldObj, newObj interface{})

type Worker

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

Worker continuously runs a Reconcile function against a message Queue

func New

func New(name string, maxRetries, threadiness int, fn func(key string) error) *Worker

func (*Worker) GetQueue

func (w *Worker) GetQueue() workqueue.RateLimitingInterface

func (*Worker) Run

func (w *Worker) Run(shutdown <-chan struct{})

Run schedules a routine to continuously process Queue messages until shutdown is closed
