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,
	hardPodAffinitySymmetricWeight int,
) 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) 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 RegisterPredicateMetadataProducerFactory 

func RegisterPredicateMetadataProducerFactory(factory MetadataProducerFactory)

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)

Types

type AlgorithmProviderConfig 

type AlgorithmProviderConfig struct {
	FitPredicateKeys     sets.String
	PriorityFunctionKeys sets.String
}

func GetAlgorithmProvider 

func GetAlgorithmProvider(name string) (*AlgorithmProviderConfig, error)

GetAlgorithmProvider should not be used to modify providers. It is publicly visible for testing.

type ConfigFactory 

type ConfigFactory struct {

	// Close this to stop all reflectors
	StopEverything chan struct{}
	// contains filtered or unexported fields
}

ConfigFactory is the default implementation of the scheduler.Configurator interface. TODO make this private if possible, so that only its interface is externally used.

func (*ConfigFactory) Create 

func (f *ConfigFactory) Create() (*scheduler.Config, error)

Create creates a scheduler with the default algorithm provider.

func (*ConfigFactory) CreateFromConfig 

func (f *ConfigFactory) CreateFromConfig(policy schedulerapi.Policy) (*scheduler.Config, error)

Creates a scheduler from the configuration file

func (*ConfigFactory) CreateFromKeys 

func (f *ConfigFactory) CreateFromKeys(predicateKeys, priorityKeys sets.String, extenders []algorithm.SchedulerExtender) (*scheduler.Config, error)

Creates a scheduler from a set of registered fit predicate keys and priority keys.

func (*ConfigFactory) CreateFromProvider 

func (f *ConfigFactory) CreateFromProvider(providerName string) (*scheduler.Config, error)

Creates a scheduler from the name of a registered algorithm provider.

func (*ConfigFactory) GetClient 

func (f *ConfigFactory) GetClient() clientset.Interface

GetClient provides a kubernetes client, mostly internal use, but may also be called by mock-tests.

func (*ConfigFactory) GetHardPodAffinitySymmetricWeight 

func (c *ConfigFactory) GetHardPodAffinitySymmetricWeight() int

func (*ConfigFactory) GetNodeLister 

func (c *ConfigFactory) GetNodeLister() corelisters.NodeLister
