Types

type ContainerScanner

type ContainerScanner struct{}

TODO: Move functions to its own implementation

func (*ContainerScanner) ReadDebianPackages

func (ct *ContainerScanner) ReadDebianPackages(layers []string) (layer int, pk *[]PackageDBEntry, err error)

ReadDebianPackages scans through a set of container layers looking for the last update to the debian package datgabase. If found, extracts it and sends it to parseDpkgDB to extract the package information from the file.

func (*ContainerScanner) ReadOSPackages

func (ct *ContainerScanner) ReadOSPackages(layers []string) (
	layerNum int, packages *[]PackageDBEntry, err error,
)

ReadOSPackages reads a bunch of layers and extracts the os package information from them, it returns the OS package and the layer where they are defined. If the OS is not supported, we return a nil pointer.

type ErrFileNotFoundInTar

type ErrFileNotFoundInTar struct{}

func (ErrFileNotFoundInTar) Error

func (e ErrFileNotFoundInTar) Error() string

type LayerScanner

type LayerScanner struct{}

TODO: Move functions to its own implementation

func (*LayerScanner) OSReleaseData

func (loss *LayerScanner) OSReleaseData(layerPath string) (osrelease string, err error)

CanHandle looks at an image tarball and checks if it looks like a debian filesystem

func (*LayerScanner) OSType

func (loss *LayerScanner) OSType(layerPath string) (ostype string, err error)

type PackageDBEntry

type PackageDBEntry struct {
	Package      string
	Version      string
	Architecture string
}
