type Volume struct {

	// VS Host + Path to the actual volume
	Host *url.URL

	// Path of the volume from the volumestore target
	Path string
}

Volume identifies an NFS based volume

func NewVolume

func NewVolume(host *url.URL, NFSPath string) Volume

func (Volume) DiskPath

func (v Volume) DiskPath() url.URL

DiskPath includes the url to the nfs directory for the container to mount,

func (Volume) MountPath

func (v Volume) MountPath() (string, error)

type VolumeStore

type VolumeStore struct {
	// volume store name
	Name string

	// Service is the interface to the nfs target.
	Service nfs.MountServer

	// Service selflink to volume store.
	SelfLink *url.URL

	// Archiver defines WriteArchive and Export interface methods
	archive.Archiver
}

VolumeStore this is nfs related volume store definition

func NewVolumeStore

func NewVolumeStore(op trace.Operation, storeName string, mount nfs.MountServer) (*VolumeStore, error)

func (*VolumeStore) Export

func (v *VolumeStore) Export(op trace.Operation, id, ancestor string, spec *archive.FilterSpec, data bool) (io.ReadCloser, error)

Export reads the delta between child and parent volume layers, returning the difference as a tar archive.

store - the volume store containing the two layers id - must inherit from ancestor if ancestor is specified ancestor - the volume layer up the chain against which to diff spec - describes filters on paths found in the data (include, exclude, strip) data - set to true to include file data in the tar archive, false to include headers only Export creates and returns a tar archive containing data found between an nfs layer one or all of its ancestors

func (*VolumeStore) Import

func (v *VolumeStore) Import(op trace.Operation, id string, spec *archive.FilterSpec, tarStream io.ReadCloser) error

Import takes a tar archive stream and extracts it into the target volume
