Types ¶

type Base ¶

type Base struct {
	*reconciler.Base
	PALister          listers.PodAutoscalerLister
	ServiceLister     corev1listers.ServiceLister
	SKSLister         nlisters.ServerlessServiceLister
	MetricLister      listers.MetricLister
	ConfigStore       reconciler.ConfigStore
	PSInformerFactory duck.InformerFactory
}

Base implements the core controller logic for autoscaling, given a Reconciler.
