Purpose

This repository is meant to be a template for building your own custom Universal Blue image. This template is the recommended way to make customizations to any image published by the Universal Blue Project:

• Aurora
• Bazzite
• Bluefin
• uCore
• main
• hwe

This template includes a Containerfile and a Github workflow for building the container image. As soon as the workflow is enabled in your repository, it will build the container image and push it to the Github Container Registry.

Community

• bootc discussion forums - Nothing in this template is ublue specific, the upstream bootc project has a discussions forum where custom image builders can hang out and ask questions.
• Index your image on artifacthub.io, use the artifacthub-repo.yml file at the root to verify yourself as the publisher.
