Types

type Controller

type Controller struct {

	// Recorder is an event Recorder for recording Event resources to the
	// Kubernetes API.
	Recorder record.EventRecorder
	// contains filtered or unexported fields
}

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	kubeInformerFactory kubeinformers.SharedInformerFactory) *Controller

NewController returns a new sample controller

func (*Controller) Run

func (c *Controller) Run(threadiness int, stopCh <-chan struct{}) error

Run will set up the event handlers for types we are interested in, as well as syncing informer caches and starting workers. It will block until stopCh is closed, at which point it will shutdown the workqueue and wait for workers to finish processing their current work items.
