	RemoveNominatedReservations(pod *corev1.Pod)
	GetNominatedReservation(pod *corev1.Pod, nodeName string) *ReservationInfo
}

ReservationNominator nominates a more suitable Reservation in the Reserve stage and Pod will bind this Reservation. The Reservation will be recorded in CycleState through SetNominatedReservation. When executing Reserve, each plugin will obtain the currently used Reservation through GetNominatedReservation, and locate the previously returned reusable resources for Pod allocation.

type ReservationPreBindPlugin added in v1.2.0 

type ReservationPreBindPlugin interface {

}

ReservationPreBindPlugin performs special binding logic specifically for Reservation in the PreBind phase. Similar to the built-in VolumeBinding plugin of kube-scheduler, it does not support Reservation, and how Reservation itself uses PVC reserved resources also needs special handling. In addition, implementing this interface can clearly indicate that the plugin supports Reservation.

type ReservationRestorePlugin added in v1.3.0 

type ReservationRestorePlugin interface {
	framework.Plugin
	PreRestoreReservation(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod) *framework.Status

	FinalRestoreReservation(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, states NodeReservationRestoreStates) *framework.Status
}

ReservationRestorePlugin is used to support the return of fine-grained resources held by Reservation, such as CPU Cores, GPU Devices, etc. During Pod scheduling, resources held by these reservations need to be allocated first, otherwise resources will be wasted.

type ReservationScore added in v1.2.0 

type ReservationScore struct {
	Name      string
	Namespace string
	UID       types.UID
	Score     int64

type ReservationScoreExtensions added in v1.4.0 

type ReservationScoreExtensions interface {
	// NormalizeReservationScore is called for all node scores produced by the same plugin's "ScoreReservation"
	// method. A successful run of NormalizeReservationScore will update the scores list and return
	// a success status.
	NormalizeReservationScore(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, scores ReservationScoreList) *framework.Status
}

ReservationScoreExtensions is an interface for Score extended functionality.

type ReservationScoreList added in v1.2.0

ReservationScoreList declares a list of reservations and their scores.

type ReservationScorePlugin added in v1.2.0 

type ReservationScorePlugin interface {
	framework.Plugin

	// ReservationScoreExtensions returns a ReservationScoreExtensions interface if it implements one, or nil if does not.
	ReservationScoreExtensions() ReservationScoreExtensions
}

ReservationScorePlugin is an interface that must be implemented by "ScoreReservation" plugins to rank reservations that passed the reserve phase.

type ResizePodPlugin added in v1.4.0 

type ResizePodPlugin interface {
	ResizePod(ctx context.Context, cycleState *framework.CycleState, pod *corev1.Pod, nodeName string) *framework.Status
}
