Functions

func GetHPATargetValue

func GetHPATargetValue(ctx context.Context, hpa *v2.HorizontalPodAutoscaler, containerName string, k corev1.ResourceName) (int32, error)

GetHPATargetValue gets the target value of the HPA. It looks for the corresponding metric (ContainerResource) and gets the target value.

func GetReplicasRecommendation

func GetReplicasRecommendation(recommendations []autoscalingv1beta3.ReplicasRecommendation, now time.Time) (int32, error)

GetReplicasRecommendation finds the corresponding recommendations.

func HasHorizontal

func HasHorizontal(tortoise *autoscalingv1beta3.Tortoise) bool
