type ControllerReference

type ControllerReference struct {
	// API version of the referent.
	APIVersion string `json:"apiVersion" protobuf:"bytes,5,opt,name=apiVersion"`
	// Kind of the referent.
	Kind string `json:"kind" protobuf:"bytes,1,opt,name=kind"`
	// Name of the referent.

	// UID of the referent.
	UID types.UID `json:"uid" protobuf:"bytes,4,opt,name=uid,casttype=k8s.io/apimachinery/pkg/types.UID"`
}

type PodControllerFinder

type PodControllerFinder func(ref ControllerReference, namespace string) (*ScaleAndSelector, error)

PodControllerFinder is a function type that maps a pod to a list of controllers and their scale.

type ScaleAndSelector

type ScaleAndSelector struct {
	ControllerReference
	// controller.spec.Replicas
	Scale int32
	// controller.spec.Selector
	Selector *metav1.LabelSelector
	// metadata
	Metadata metav1.ObjectMeta
}

ScaleAndSelector is used to return (controller, scale, selector) fields from the controller finder functions.
