NAME

Container::Builder::Layer::DebianPackageFile - Make a container layer based upon a Debian package file.

DESCRIPTION

Container::Builder::Layer::DebianPackageFile implements Container::Builder::Layer and can be used to create container layers based upon a debian package file.

METHODS

new(file => 'mypackage.deb', compress => 1)

new(data => 'a valid deb archive string', compress => 1)

Create a Container::Builder::Layer::DebianPackageFile object. Pass in either the filename with file or pass the debian archive data as a scalar with data. The compress argument controls whether we return a Gzipped archive as a layer or a plain TAR file.

generate_artifact()

Returns a TAR (gzipped or not) file that is based upon the Debian package data.tar.xz archive contents. This method will unpack the .deb using Ar. And then decompress the XZ archive to get the TAR data from the Debian package.

get_media_type()

Return the media type of the container. This is the mime type of the layer. Possibilities are application/vnd.oci.image.layer.v1.tar or application/vnd.oci.image.layer.v1.tar+gzip.

get_digest()

Returns the SHA256 digest of the generated layer.

get_size()

Returns the size (length) of the generated layer.
