)

type UtilizationShapePoint added in v1.17.0

type UtilizationShapePoint struct {
	// Utilization (x axis). Valid values are 0 to 100. Fully utilized node maps to 100.
	Utilization int32
	// Score assigned to a given utilization (y axis). Valid values are 0 to 10.
	Score int32
}

UtilizationShapePoint represents a single point of a priority function shape.

func (*UtilizationShapePoint) DeepCopy added in v1.17.0

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new UtilizationShapePoint.

func (*UtilizationShapePoint) DeepCopyInto added in v1.17.0

func (in *UtilizationShapePoint) DeepCopyInto(out *UtilizationShapePoint)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type VolumeBindingArgs added in v1.19.0

type VolumeBindingArgs struct {
	metav1.TypeMeta

	// BindTimeoutSeconds is the timeout in seconds in volume binding operation.
	// Value must be non-negative integer. The value zero indicates no waiting.
	// If this value is nil, the default value will be used.
	BindTimeoutSeconds int64

	// Shape specifies the points defining the score function shape, which is
	// used to score nodes based on the utilization of statically provisioned
	// PVs. The utilization is calculated by dividing the total requested
	// storage of the pod by the total capacity of feasible PVs on each node.
	// Each point contains utilization (ranges from 0 to 100) and its
	// associated score (ranges from 0 to 10). You can turn the priority by
	// specifying different scores for different utilization numbers.
	// The default shape points are:
	// 1) 0 for 0 utilization
	// 2) 10 for 100 utilization
	// All points must be sorted in increasing order by utilization.
	// +featureGate=VolumeCapacityPriority
	// +optional
	Shape []UtilizationShapePoint
}

VolumeBindingArgs holds arguments used to configure the VolumeBinding plugin.
