MakeDefaultErrorFunc is not implemented yet.

type Option

type Option func(*schedulerOptions)

Option configures a Scheduler

func WithBindTimeoutSeconds

func WithBindTimeoutSeconds(bindTimeoutSeconds int64) Option

WithBindTimeoutSeconds sets bindTimeoutSeconds for Scheduler, the default value is 100

func WithHardPodAffinitySymmetricWeight

func WithHardPodAffinitySymmetricWeight(hardPodAffinitySymmetricWeight int32) Option

WithHardPodAffinitySymmetricWeight sets hardPodAffinitySymmetricWeight for Scheduler, the default value is 1

func WithName

func WithName(schedulerName string) Option

WithName sets schedulerName for Scheduler, the default schedulerName is default-scheduler

func WithPercentageOfNodesToScore

func WithPercentageOfNodesToScore(percentageOfNodesToScore int32) Option

WithPercentageOfNodesToScore sets percentageOfNodesToScore for Scheduler, the default value is 50

func WithPreemptionDisabled

func WithPreemptionDisabled(disablePreemption bool) Option

WithPreemptionDisabled sets disablePreemption for Scheduler, the default value is false

type Scheduler

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

Scheduler watches for new unscheduled pods. It attempts to find nodes that they fit on and writes bindings back to the api server.

func New

func New(client clientset.Interface,
	nodeInformer coreinformers.NodeInformer,
	podInformer coreinformers.PodInformer,
	pvInformer coreinformers.PersistentVolumeInformer,
	pvcInformer coreinformers.PersistentVolumeClaimInformer,
	replicationControllerInformer coreinformers.ReplicationControllerInformer,
	replicaSetInformer appsinformers.ReplicaSetInformer,

	recorder record.EventRecorder,
	schedulerAlgorithmSource kubeschedulerconfig.SchedulerAlgorithmSource,
	stopCh <-chan struct{},
	opts ...func(o *schedulerOptions)) (*Scheduler, error)

New returns a Scheduler

func NewFromConfig

func NewFromConfig(config *factory.Config) *Scheduler

NewFromConfig returns a new scheduler using the provided Config.

func NewFromConfigurator

func NewFromConfigurator(c factory.Configurator, modifiers ...func(c *factory.Config)) (*Scheduler, error)

NewFromConfigurator returns a new scheduler that is created entirely by the Configurator. Assumes Create() is implemented. Supports intermediate Config mutation for now if you provide modifier functions which will run after Config is created.

func (*Scheduler) Cache

func (sched *Scheduler) Cache() schedulerinternalcache.Cache

Cache returns the cache in scheduler for test to check the data in scheduler.

func (*Scheduler) Config

func (sched *Scheduler) Config() *factory.Config

Config returns scheduler's config pointer. It is exposed for testing purposes.

func (*Scheduler) Run

func (sched *Scheduler) Run()

Run begins watching and scheduling. It waits for cache to be synced, then starts a goroutine and returns immediately.
