Functions

func CopyFileFromDeb

func CopyFileFromDeb(filename string, debReader io.Reader, writer io.Writer) error

CopyFileFromDeb copies a file from the debian file to a writer.

func DebToLayer

func DebToLayer(debReader io.Reader, writer io.Writer) error

DebToLayer convernts a deb package into a tar file that can be used as a layer in an OCI image. Including adding the appropriate files for dpkg to track the package.

This approach has a few limitations:

• We don't pay attention to the metadata in the control file, including the additional dependencies that may be decalared or checking that the architecture is correct.
• Any package mantainer scripts will not be run, which breaks some packages entirely.
