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) (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,
	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
