Types

type AttachDetachController

type AttachDetachController interface {
	Run(stopCh <-chan struct{})
	GetDesiredStateOfWorld() cache.DesiredStateOfWorld
}

AttachDetachController defines the operations supported by this controller.

func NewAttachDetachController

func NewAttachDetachController(
	kubeClient clientset.Interface,
	podInformer coreinformers.PodInformer,
	nodeInformer coreinformers.NodeInformer,
	pvcInformer coreinformers.PersistentVolumeClaimInformer,
	pvInformer coreinformers.PersistentVolumeInformer,
	csiNodeInformer storageinformers.CSINodeInformer,
	csiDriverInformer storageinformers.CSIDriverInformer,
	cloud cloudprovider.Interface,
	plugins []volume.VolumePlugin,
	prober volume.DynamicPluginProber,
	disableReconciliationSync bool,
	reconcilerSyncDuration time.Duration,
	timerConfig TimerConfig) (AttachDetachController, error)

NewAttachDetachController returns a new instance of AttachDetachController.

type TimerConfig

type TimerConfig struct {
	// ReconcilerLoopPeriod is the amount of time the reconciler loop waits
	// between successive executions
	ReconcilerLoopPeriod time.Duration

	// ReconcilerMaxWaitForUnmountDuration is the maximum amount of time the
	// attach detach controller will wait for a volume to be safely unmounted
	// from its node. Once this time has expired, the controller will assume the
	// node or kubelet are unresponsive and will detach the volume anyway.
	ReconcilerMaxWaitForUnmountDuration time.Duration

	// DesiredStateOfWorldPopulatorLoopSleepPeriod is the amount of time the
	// DesiredStateOfWorldPopulator loop waits between successive executions
	DesiredStateOfWorldPopulatorLoopSleepPeriod time.Duration

	// DesiredStateOfWorldPopulatorListPodsRetryDuration is the amount of
	// time the DesiredStateOfWorldPopulator loop waits between list pods
	// calls.
	DesiredStateOfWorldPopulatorListPodsRetryDuration time.Duration
}

TimerConfig contains configuration of internal attach/detach timers and should be used only to speed up tests. DefaultTimerConfig is the suggested timer configuration for production.

var DefaultTimerConfig TimerConfig = TimerConfig{
	ReconcilerLoopPeriod:                              100 * time.Millisecond,
	ReconcilerMaxWaitForUnmountDuration:               6 * time.Minute,
	DesiredStateOfWorldPopulatorLoopSleepPeriod:       1 * time.Minute,
	DesiredStateOfWorldPopulatorListPodsRetryDuration: 3 * time.Minute,
}

DefaultTimerConfig is the default configuration of Attach/Detach controller timers.
