images/image-builder/config/README.md

The generate_iso and package_qcow make target can be used to build ISO and QCOW artifacts respectively, after the shared image-builder container is built (built with the build target).

By default, one image will be built for each subdirectory that matches the corresponding IMAGE_TYPE for the build.

In other words, ISOs will be built using files from subdirs with names starting with iso*, while QCOWs are built from subdirs with names starting with qcow*. If you want to build QCOWs from an explicit list of dirs, you can supply them using the QCOW_CONF_DIRS parameter to the makefile.

ISOs expect the following files to be present in their directory:

• user_data - YAML file containing cloud-init user-data
• network_data.json - JSON file containing cloud-init network data
• img_name - text file containing the desired name for the image

Note that ISO generation here is only for testing. It is not published or promoted anywhere.

QCOWs expect the following files to be present in their directory:

• osconfig-*-vars.yaml - YAML file containing osconfig playbook overrides
• qcow-*-vars.yaml - YAML file containing qcow playboook overrides
• img_name - text file containing the desired name for the image
