Types

type DaemonSetsController

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

DaemonSetsController is responsible for synchronizing DaemonSet objects stored in the system with actual running pods.

func NewDaemonSetsController

func NewDaemonSetsController(daemonSetInformer extensionsinformers.DaemonSetInformer, podInformer coreinformers.PodInformer, nodeInformer coreinformers.NodeInformer, kubeClient clientset.Interface, lookupCacheSize int) *DaemonSetsController

func (*DaemonSetsController) Run

func (dsc *DaemonSetsController) Run(workers int, stopCh <-chan struct{})

Run begins watching and syncing daemon sets.
