Using KIWI NG in a Python Project¶
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 9.16.27.
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 # Import of log handler only needed if default logging # setup is not appropriate for the project # from kiwi.logger import log # By default the logging level is set to DEBUG, which # can be changed by the following call # log.setLogLevel(logging.INFO) # Logging can also be disabled completely # log.disabled = True 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…
