Functions ¶

func ApplyLayer ¶

func ApplyLayer(dest string, layer io.Reader) (size int64, err error)

ApplyLayer parses a diff in the standard layer format from `layer`, and applies it to the directory `dest`. The stream `layer` can only be uncompressed. Returns the size in bytes of the contents of the layer.

func ApplyUncompressedLayer ¶

func ApplyUncompressedLayer(dest string, layer io.Reader, options *archive.TarOptions) (int64, error)

ApplyUncompressedLayer parses a diff in the standard layer format from `layer`, and applies it to the directory `dest`. The stream `layer` can only be uncompressed. Returns the size in bytes of the contents of the layer.

func NewArchiver ¶

func NewArchiver(idMappings *idtools.IDMappings) *archive.Archiver

NewArchiver returns a new Archiver which uses chrootarchive.Untar

func Untar ¶

func Untar(tarArchive io.Reader, dest string, options *archive.TarOptions) error

Untar reads a stream of bytes from `archive`, parses it as a tar archive, and unpacks it into the directory at `dest`. The archive may be compressed with one of the following algorithms:

identity (uncompressed), gzip, bzip2, xz.

func UntarUncompressed ¶

func UntarUncompressed(tarArchive io.Reader, dest string, options *archive.TarOptions) error

UntarUncompressed reads a stream of bytes from `archive`, parses it as a tar archive, and unpacks it into the directory at `dest`. The archive must be an uncompressed stream.
