anaconda-iso

Bootc artifact image type anaconda-iso.

The bootable container is an input; Image Builder turns it into this output artifact. Customize via a blueprint / config.toml using only the options listed below (see Blueprint Reference).

Compatibility image type

anaconda-iso is kept for compatibility with older bootc-image-builder workflows and is on its way out. Prefer bootc-generic-iso or bootc-installer for new ISO work.

Supported blueprint customizations

Blueprint fields accepted for this bootc image type (from bootc-generic/imagetypes.yaml in osbuild/image-builder). See the Blueprint Reference for syntax and examples. The metadata fields name, version, and description are always accepted and omitted below.

Supported options:

• customizations.fips
• customizations.group
• customizations.installer
• customizations.kernel.append
• customizations.user

Container input, not package sets

Bootc images are built from a container reference (--bootc-ref), not from a distribution RPM base package set. Package content comes from the container image itself.

Do not rely on the image description format

The format of these pages is not guaranteed to be stable. It is published for informational purposes only.
