Types

type AnnotationFunc

type AnnotationFunc func(currentReplicas int32, annotations map[string]string)

type ScaleAnnotater

type ScaleAnnotater struct {
	ChangeAnnotations AnnotationFunc
	// contains filtered or unexported fields
}

func (*ScaleAnnotater) GetObjectWithScale

func (c *ScaleAnnotater) GetObjectWithScale(namespace string, ref unidlingapi.CrossGroupObjectReference) (runtime.Object, *kextapi.Scale, error)

getObjectWithScale either fetches a known type of object and constructs a Scale from that, or uses the scale subresource to fetch a Scale by itself.

func (*ScaleAnnotater) UpdateObjectScale

func (c *ScaleAnnotater) UpdateObjectScale(updater ScaleUpdater, namespace string, ref unidlingapi.CrossGroupObjectReference, obj runtime.Object, scale *kextapi.Scale) error

updateObjectScale updates the scale of an object and removes unidling annotations for objects of a know type. For objects of an unknown type, it scales the object using the scale subresource (and does not change annotations).

type ScaleUpdater

type ScaleUpdater interface {
	Update(*ScaleAnnotater, runtime.Object, *kextapi.Scale) error
}

ScaleUpdater implements a method "Update" that knows how to update a given object
