Types

type UpdateConfig

type UpdateConfig struct {
	// MinChangePriority is the minimum change priority that will trigger a update.
	// TODO: should have separate for Mem and CPU?
	MinChangePriority float64
}

UpdateConfig holds configuration for UpdatePriorityCalculator

type UpdatePriorityCalculator

type UpdatePriorityCalculator struct {
	// contains filtered or unexported fields
}

UpdatePriorityCalculator is responsible for prioritizing updates on pods. It can returns a sorted list of pods in order of update priority. Update priority is proportional to fraction by which resources should be increased / decreased. i.e. pod with 10M current memory and recommendation 20M will have higher update priority than pod with 100M current memory and 150M recommendation (100% increase vs 50% increase)

func NewUpdatePriorityCalculator

func NewUpdatePriorityCalculator(policy *vpa_types.PodResourcePolicy, config *UpdateConfig) UpdatePriorityCalculator

NewUpdatePriorityCalculator creates new UpdatePriorityCalculator for the given resources policy and configuration. If the given policy is nil, there will be no policy restriction on update. If the given config is nil, default values are used.

func (*UpdatePriorityCalculator) AddPod

func (calc *UpdatePriorityCalculator) AddPod(pod *apiv1.Pod, recommendation *vpa_types.RecommendedPodResources)

AddPod adds pod to the UpdatePriorityCalculator.

func (*UpdatePriorityCalculator) GetSortedPods

func (calc *UpdatePriorityCalculator) GetSortedPods() []*apiv1.Pod

GetSortedPods returns a list of pods ordered by update priority (highest update priority first)
