Documentation

Overview

Package factory can set up a scheduler. This code is here instead of plugin/cmd/scheduler for both testability and reuse.

Functions

func IsFitPredicateRegistered

func IsFitPredicateRegistered(name string) bool

IsFitPredicateRegistered is useful for testing providers.

func IsPriorityFunctionRegistered

func IsPriorityFunctionRegistered(name string) bool

IsPriorityFunctionRegistered is useful for testing providers.

func ListAlgorithmProviders

func ListAlgorithmProviders() string

ListAlgorithmProviders is called when listing all available algorithm providers in `kube-scheduler --help`

func ListRegisteredFitPredicates

func ListRegisteredFitPredicates() []string

func ListRegisteredPriorityFunctions

func ListRegisteredPriorityFunctions() []string

func NewConfigFactory

func NewConfigFactory(
	schedulerName string,
	client clientset.Interface,
	nodeInformer coreinformers.NodeInformer,
	podInformer coreinformers.PodInformer,
	pvInformer coreinformers.PersistentVolumeInformer,
	pvcInformer coreinformers.PersistentVolumeClaimInformer,
	replicationControllerInformer coreinformers.ReplicationControllerInformer,
	replicaSetInformer extensionsinformers.ReplicaSetInformer,
	statefulSetInformer appsinformers.StatefulSetInformer,
	serviceInformer coreinformers.ServiceInformer,
	pdbInformer policyinformers.PodDisruptionBudgetInformer,
	hardPodAffinitySymmetricWeight int,
	enableEquivalenceClassCache bool,
) scheduler.Configurator

NewConfigFactory initializes the default implementation of a Configurator To encourage eventual privatization of the struct type, we only return the interface.

func NewPodInformer

func NewPodInformer(client clientset.Interface, resyncPeriod time.Duration, schedulerName string) coreinformers.PodInformer

NewPodInformer creates a shared index informer that returns only non-terminal pods.

func RegisterAlgorithmProvider

func RegisterAlgorithmProvider(name string, predicateKeys, priorityKeys sets.String) string

RegisterAlgorithmProvider registers a new algorithm provider with the algorithm registry. This should be called from the init function in a provider plugin.

func RegisterCustomFitPredicate

func RegisterCustomFitPredicate(policy schedulerapi.PredicatePolicy) string

RegisterCustomFitPredicate registers a custom fit predicate with the algorithm registry. Returns the name, with which the predicate was registered.

func RegisterCustomPriorityFunction

func RegisterCustomPriorityFunction(policy schedulerapi.PriorityPolicy) string

RegisterCustomPriorityFunction registers a custom priority function with the algorithm registry. Returns the name, with which the priority function was registered.

func RegisterFitPredicate

func RegisterFitPredicate(name string, predicate algorithm.FitPredicate) string

RegisterFitPredicate registers a fit predicate with the algorithm registry. Returns the name with which the predicate was registered.

func RegisterFitPredicateFactory

func RegisterFitPredicateFactory(name string, predicateFactory FitPredicateFactory) string

RegisterFitPredicateFactory registers a fit predicate factory with the algorithm registry. Returns the name with which the predicate was registered.

func RegisterGetEquivalencePodFunction

func RegisterGetEquivalencePodFunction(equivalenceFunc algorithm.GetEquivalencePodFunc)

func RegisterMandatoryFitPredicate

func RegisterMandatoryFitPredicate(name string, predicate algorithm.FitPredicate) string

RegisterMandatoryFitPredicate registers a fit predicate with the algorithm registry, the predicate is used by kubelet, DaemonSet; it is always included in configuration. Returns the name with which the predicate was registered.

func RegisterPredicateMetadataProducerFactory

func RegisterPredicateMetadataProducerFactory(factory PredicateMetadataProducerFactory)

func RegisterPriorityConfigFactory

func RegisterPriorityConfigFactory(name string, pcf PriorityConfigFactory) string

func RegisterPriorityFunction

func RegisterPriorityFunction(name string, function algorithm.PriorityFunction, weight int) string

DEPRECATED Use Map-Reduce pattern for priority functions. Registers a priority function with the algorithm registry. Returns the name, with which the function was registered.

func RegisterPriorityFunction2

func RegisterPriorityFunction2(
	name string,
	mapFunction algorithm.PriorityMapFunction,
	reduceFunction algorithm.PriorityReduceFunction,
	weight int) string

RegisterPriorityFunction2 registers a priority function with the algorithm registry. Returns the name, with which the function was registered. FIXME: Rename to PriorityFunctionFactory.

func RegisterPriorityMetadataProducerFactory

func RegisterPriorityMetadataProducerFactory(factory MetadataProducerFactory)

func RemoveFitPredicate

func RemoveFitPredicate(name string)

RemoveFitPredicate removes a fit predicate from factory.
