Functions

func CompressedTarReader

func CompressedTarReader(ctx context.Context, r io.ReadSeeker, unpacker []string, sysOS *sys.OS, outputPath string) (*tar.Reader, context.CancelFunc, error)

CompressedTarReader returns a tar reader from the supplied (optionally compressed) tarball stream. The unpacker arguments are those returned by DetectCompressionFile(). The returned cancelFunc should be called when finished with reader to clean up any resources used. This can be done before reading to the end of the tarball if desired.

func ExtractWithFds

func ExtractWithFds(cmd string, args []string, allowedCmds []string, stdin io.ReadCloser, sysOS *sys.OS, output *os.File) error

ExtractWithFds runs extractor process under specifc AppArmor profile. The allowedCmds argument specify commands which are allowed to run by apparmor. The cmd argument is automatically added to allowedCmds slice.

func Unpack

func Unpack(file string, path string, blockBackend bool, sysOS *sys.OS, tracker *ioprogress.ProgressTracker) error

Unpack extracts image from archive.
