Using KIWI NG in a Python Project

Hint

Abstract

KIWI is provided as python module under the kiwi namespace. It is available for the python 2 and 3 versions. The following description applies for KIWI version 9.19.6.

KIWI NG can also function as a module for other Python projects. The following example demonstrates how to read an existing image description, add a new repository definition and export the modified description on stdout.

import sys
import logging

from kiwi.xml_description import XMLDescription
from kiwi.xml_state import XMLState

description = XMLDescription('path/to/kiwi/XML/config.xml')

xml_data = description.load()

xml_state = XMLState(
    xml_data=xml_data, profiles=[], build_type='iso'
)

xml_state.add_repository(
    repo_source='http://repo',
    repo_type='rpm-md',
    repo_alias='myrepo',
    repo_prio=99
)

xml_data.export(
    outfile=sys.stdout, level=0
)

All classes are written in a way to care for a single responsibility in order to allow for re-use on other use cases. Therefore it is possible to use KIWI NG outside of the main image building scope to manage e.g the setup of loop devices, filesystems, partitions, etc…
