Functions

func FilterControlledResources

func FilterControlledResources(estimation model.Resources, controlledResources []model.ResourceName) model.Resources

Types

type PodResourceRecommender

type PodResourceRecommender interface {
	GetRecommendedPodResources(containerNameToAggregateStateMap model.ContainerNameToAggregateStateMap) RecommendedPodResources
}

PodResourceRecommender computes resource recommendation for a Vpa object.

func CreatePodResourceRecommender

func CreatePodResourceRecommender() PodResourceRecommender

type RecommendedContainerResources

type RecommendedContainerResources struct {
	// Recommended optimal amount of resources.
	Target model.Resources
	// Recommended minimum amount of resources.
	LowerBound model.Resources
	// Recommended maximum amount of resources.
	UpperBound model.Resources
}

RecommendedContainerResources is the recommendation of resources for a container.

type RecommendedPodResources

type RecommendedPodResources map[string]RecommendedContainerResources

RecommendedPodResources is a Map from container name to recommended resources.

type ResourceEstimator

type ResourceEstimator interface {
	GetResourceEstimation(s *model.AggregateContainerState) model.Resources
}

ResourceEstimator is a function from AggregateContainerState to model.Resources, e.g. a prediction of resources needed by a group of containers.
