}

type ControllerContext

type ControllerContext struct {
	ClientBuilder *clients.Builder

	NamespacedInformerFactory                    mcfginformers.SharedInformerFactory
	InformerFactory                              mcfginformers.SharedInformerFactory
	KubeInformerFactory                          informers.SharedInformerFactory
	KubeNamespacedInformerFactory                informers.SharedInformerFactory
	OpenShiftConfigKubeNamespacedInformerFactory informers.SharedInformerFactory
	APIExtInformerFactory                        apiextinformers.SharedInformerFactory
	ConfigInformerFactory                        configinformers.SharedInformerFactory

	AvailableResources map[schema.GroupVersionResource]bool

	Stop <-chan struct{}

	InformersStarted chan struct{}

	ResyncPeriod func() time.Duration
}

ControllerContext stores all the informers for a variety of kubernetes objects.
