Constants

const CloudVolumeCreatedForClaimNameTag = "kubernetes.io/created-for/pvc/name"

CloudVolumeCreatedForClaimNameTag is a name of a tag attached to a real volume in cloud (e.g. AWS EBS or GCE PD) with name of a persistent volume claim used to create this volume.

const CloudVolumeCreatedForClaimNamespaceTag = "kubernetes.io/created-for/pvc/namespace"

CloudVolumeCreatedForClaimNamespaceTag is a name of a tag attached to a real volume in cloud (e.g. AWS EBS or GCE PD) with namespace of a persistent volume claim used to create this volume.

const CloudVolumeCreatedForVolumeNameTag = "kubernetes.io/created-for/pv/name"

CloudVolumeCreatedForVolumeNameTag is a name of a tag attached to a real volume in cloud (e.g. AWS EBS or GCE PD) with name of appropriate Kubernetes persistent volume .

Types

type CSIMigratedPluginManager

type CSIMigratedPluginManager interface {
	IsMigrationEnabledForPlugin(pluginName string) bool
}

CSIMigratedPluginManager keeps track of CSI migration status of a plugin

type CSINameTranslator

type CSINameTranslator interface {
	GetCSINameFromInTreeName(pluginName string) (string, error)
}

CSINameTranslator can get the CSI Driver name based on the in-tree plugin name

type ControllerParameters

type ControllerParameters struct {
	KubeClient                clientset.Interface
	SyncPeriod                time.Duration
	VolumePlugins             []vol.VolumePlugin
	Cloud                     cloudprovider.Interface
	ClusterName               string
	VolumeInformer            coreinformers.PersistentVolumeInformer
	ClaimInformer             coreinformers.PersistentVolumeClaimInformer
	ClassInformer             storageinformers.StorageClassInformer
	PodInformer               coreinformers.PodInformer
	NodeInformer              coreinformers.NodeInformer
	EventRecorder             record.EventRecorder

}

ControllerParameters contains arguments for creation of a new PersistentVolume controller.

type PersistentVolumeController

type PersistentVolumeController struct {
	NodeLister       corelisters.NodeLister
	NodeListerSynced cache.InformerSynced
	// contains filtered or unexported fields
}

PersistentVolumeController is a controller that synchronizes PersistentVolumeClaims and PersistentVolumes. It starts two cache.Controllers that watch PersistentVolume and PersistentVolumeClaim changes.
