Functions

func Walk

func Walk(tarReader tar.Reader, walkFunc func(t *TarFile) error) error

Walk walks through the files in the tarball represented by tarstream and passes each of them to the WalkFunc provided as an argument

Types

type FileBackend

type FileBackend struct {
	// contains filtered or unexported fields
}

func NewFileBackend

func NewFileBackend(file *os.File) *FileBackend

func (*FileBackend) GetImageInfo

func (lb *FileBackend) GetImageInfo(dockerURL string) ([]string, *attr.ParsedDockerURL, error)

func (*FileBackend) GetLayerInfo

func (lb *FileBackend) GetLayerInfo(layerID string, dockerURL *attr.ParsedDockerURL) (*attr.DockerImageData, error)

type TarFile

type TarFile struct {
	Header    *tar.Header
	TarStream io.Reader
}

TarFile is a representation of a file in a tarball. It consists of two parts, the Header and the Stream. The Header is a regular tar header, the Stream is a byte stream that can be used to read the file's contents

func (*TarFile) Linkname

func (t *TarFile) Linkname() string

Linkname returns the Linkname of the file as reported by the header

func (*TarFile) Name

func (t *TarFile) Name() string

Name returns the name of the file as reported by the header

type WalkFunc

type WalkFunc func(t *TarFile) error

WalkFunc is a func for handling each file (header and byte stream) in a tarball
