Types

type ExpandController

type ExpandController interface {
	Run(stopCh <-chan struct{})
}

ExpandController expands the pvs

func NewExpandController

func NewExpandController(
	kubeClient clientset.Interface,
	pvcInformer coreinformers.PersistentVolumeClaimInformer,
	pvInformer coreinformers.PersistentVolumeInformer,
	cloud cloudprovider.Interface,
	plugins []volume.VolumePlugin,
	prober volume.DynamicPluginProber) (ExpandController, error)

type PVCPopulator

type PVCPopulator interface {
	Run(stopCh <-chan struct{})
}

PVCPopulator iterates through PVCs and checks if for bound PVCs their size doesn't match with Persistent Volume size

func NewPVCPopulator

func NewPVCPopulator(
	loopPeriod time.Duration,
	resizeMap cache.VolumeResizeMap,
	pvcLister corelisters.PersistentVolumeClaimLister,
	pvLister corelisters.PersistentVolumeLister,
	volumePluginMgr *volume.VolumePluginMgr,
	kubeClient clientset.Interface) PVCPopulator

type SyncVolumeResize

type SyncVolumeResize interface {
	Run(stopCh <-chan struct{})
}

func NewSyncVolumeResize

func NewSyncVolumeResize(
	loopPeriod time.Duration,
	opsExecutor operationexecutor.OperationExecutor,
	resizeMap cache.VolumeResizeMap,
	kubeClient clientset.Interface) SyncVolumeResize

NewSyncVolumeResize returns actual volume resize handler
