Functions

func NewDefaultRegistry

func NewDefaultRegistry(args *RegistryArgs) framework.Registry

NewDefaultRegistry builds a default registry with all the default plugins. This is the registry that Kubernetes default scheduler uses. A scheduler that runs custom plugins, can pass a different Registry when initializing the scheduler.

Types

type ConfigProducer

type ConfigProducer func(args ConfigProducerArgs) (config.Plugins, []config.PluginConfig)

ConfigProducer produces a framework's configuration.

type ConfigProducerArgs

type ConfigProducerArgs struct {
	// Weight used for priority functions.
	Weight int32
}

ConfigProducerArgs contains arguments that are passed to the producer. As we add more predicates/priorities to framework plugins mappings, more arguments may be added here.

type ConfigProducerRegistry

type ConfigProducerRegistry struct {
	// maps that associate predicates/priorities with framework plugin configurations.
	PredicateToConfigProducer map[string]ConfigProducer
	PriorityToConfigProducer  map[string]ConfigProducer
}

ConfigProducerRegistry tracks mappings from predicates/priorities to framework config producers.

func NewDefaultConfigProducerRegistry

func NewDefaultConfigProducerRegistry() *ConfigProducerRegistry

NewDefaultConfigProducerRegistry creates a new producer registry.

func (*ConfigProducerRegistry) RegisterPredicate

func (f *ConfigProducerRegistry) RegisterPredicate(name string, producer ConfigProducer) error

RegisterPredicate registers a config producer for a predicate.

func (*ConfigProducerRegistry) RegisterPriority

func (f *ConfigProducerRegistry) RegisterPriority(name string, producer ConfigProducer) error

RegisterPriority registers a framework config producer for a priority.

type RegistryArgs

type RegistryArgs struct {
	SchedulerCache     internalcache.Cache
	ServiceLister      algorithm.ServiceLister
	ControllerLister   algorithm.ControllerLister
	ReplicaSetLister   algorithm.ReplicaSetLister
	StatefulSetLister  algorithm.StatefulSetLister
	PDBLister          algorithm.PDBLister
	PVLister           corelisters.PersistentVolumeLister
	PVCLister          corelisters.PersistentVolumeClaimLister
	StorageClassLister storagelistersv1.StorageClassLister
	VolumeBinder       *volumebinder.VolumeBinder
}

RegistryArgs arguments needed to create default plugin factories.
