Functions

func GetContainersResources

func GetContainersResources(pod *core.Pod, podRecommendation vpa_types.RecommendedPodResources, limitRange *core.LimitRangeItem,
	annotations vpa_api_util.ContainerToAnnotationsMap) []vpa_api_util.ContainerResources

GetContainersResources returns the recommended resources for each container in the given pod in the same order they are specified in the pod.Spec.

func NewRecommendationProvider

func NewRecommendationProvider(calculator limitrange.LimitRangeCalculator, recommendationProcessor vpa_api_util.RecommendationProcessor,
	selectorFetcher target.VpaTargetSelectorFetcher, vpaLister vpa_lister.VerticalPodAutoscalerLister) *recommendationProvider

NewRecommendationProvider constructs the recommendation provider that list VPAs and can be used to determine recommendations for pods.

Types

type AdmissionServer

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

AdmissionServer is an admission webhook server that modifies pod resources request based on VPA recommendation

func NewAdmissionServer

func NewAdmissionServer(recommendationProvider RecommendationProvider, podPreProcessor PodPreProcessor, vpaPreProcessor VpaPreProcessor, limitsChecker limitrange.LimitRangeCalculator) *AdmissionServer

NewAdmissionServer constructs new AdmissionServer

func (*AdmissionServer) Serve

func (s *AdmissionServer) Serve(w http.ResponseWriter, r *http.Request)

Serve is a handler function of AdmissionServer

type NoopPreProcessor

type NoopPreProcessor struct{}

NoopPreProcessor leaves pods unchanged when processing

func (*NoopPreProcessor) Process

func (p *NoopPreProcessor) Process(pod apiv1.Pod) (apiv1.Pod, error)

Process leaves the pod unchanged

type PodPreProcessor

type PodPreProcessor interface {
	Process(apiv1.Pod) (apiv1.Pod, error)
}

PodPreProcessor processes the pods before building patches.

func NewDefaultPodPreProcessor

func NewDefaultPodPreProcessor() PodPreProcessor

NewDefaultPodPreProcessor creates a default PodPreProcessor

type RecommendationProvider

type RecommendationProvider interface {
	GetContainersResourcesForPod(pod *core.Pod) ([]vpa_api_util.ContainerResources, vpa_api_util.ContainerToAnnotationsMap, string, error)
}

RecommendationProvider gets current recommendation, annotations and vpaName for the given pod.

type VpaPreProcessor

type VpaPreProcessor interface {
	Process(vpa *vpa_types.VerticalPodAutoscaler, isCreate bool) (*vpa_types.VerticalPodAutoscaler, error)
}

VpaPreProcessor processes the VPAs before applying default .

func NewDefaultVpaPreProcessor

func NewDefaultVpaPreProcessor() VpaPreProcessor

NewDefaultVpaPreProcessor creates a VpaPreProcessor that leaves VPAs unchanged and returns no error
