Types

type VolumeMigrationService

type VolumeMigrationService interface {
	// GetVolumeID returns VolumeID for a given VolumeSpec.
	// Returns an error if not able to retrieve VolumeID.
	GetVolumeID(ctx context.Context, volumeSpec *VolumeSpec) (string, error)

	// GetVolumePath returns VolumePath for a given VolumeID.
	// Returns an error if not able to retrieve VolumePath.
	GetVolumePath(ctx context.Context, volumeID string) (string, error)

	// DeleteVolumeInfo helps delete mapping of volumePath to VolumeID for
	// specified volumeID.
	DeleteVolumeInfo(ctx context.Context, volumeID string) error
}

VolumeMigrationService exposes interfaces to support VCP to CSI migration. It will maintain internal state to map volume path to volume ID and reverse mapping.

func GetVolumeMigrationService

func GetVolumeMigrationService(ctx context.Context, volumeManager *cnsvolume.Manager,
	cnsConfig *cnsconfig.Config, runCleanupRoutine bool) (VolumeMigrationService, error)

GetVolumeMigrationService returns the singleton VolumeMigrationService. Starts a cleanup routine to delete stale CRD instances if needed.

type VolumeSpec

type VolumeSpec struct {
	VolumePath        string
	StoragePolicyName string
}

VolumeSpec contains VolumePath and StoragePolicyID, using which Volume can be looked up via VolumeMigrationService.
