type InTreeToCSITranslator added in v1.18.0

type InTreeToCSITranslator interface {
	IsPVMigratable(pv *v1.PersistentVolume) bool
	IsMigratableIntreePluginByName(inTreePluginName string) bool
	GetInTreePluginNameFromSpec(pv *v1.PersistentVolume, vol *v1.Volume) (string, error)
	GetCSINameFromInTreeName(pluginName string) (string, error)
	TranslateInTreePVToCSI(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)
}

InTreeToCSITranslator contains methods required to check migratable status and perform translations from InTree PV's to CSI

type VolumeFilter added in v1.18.0

type VolumeFilter struct {
	// Filter normal volumes
	FilterVolume           func(vol *v1.Volume) (id string, relevant bool)
	FilterPersistentVolume func(pv *v1.PersistentVolume) (id string, relevant bool)
	// MatchProvisioner evaluates if the StorageClass provisioner matches the running predicate
	MatchProvisioner func(sc *storage.StorageClass) (relevant bool)
	// IsMigrated returns a boolean specifying whether the plugin is migrated to a CSI driver
