Using Konflux to build Fedora CoreOS

This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

The Fedora CoreOS working group would like to start using the Konflux container build workflow to build Fedora CoreOS. With the work done in https://fedoraproject.org/wiki/Changes/OstreeNativeContainerStable it is now possible to use Dockerfile/Containerfile to build ostree based editions. The goal of this change is to deploy a instance of Konflux https://konflux-ci.dev/ in Fedora's infrastructure and start using the container build workflow to build Fedora CoreOS.

Detailed Description

With the release of bootable containers, it is now possible to use the container build and release infrastructure for ostree editions. Fedora CoreOS would like to make use of these capabilities and start to migrate to Konflux. The current build and test pipeline of Fedora CoreOS is built on top of Jenkins and does many things, the goal of this change is to migrate the current solution used to build the Fedora CoreOS bootable containers from the Jenkins pipeline to Konflux. The scope of this change for the Fedora 42 timeline is:

1. Get Konflux deployed in Fedora Infrastructure (we need help from Fedora Infra as well as the Konflux team). Fedora CoreOS currently supports x86, aarch64, ppc64le and s390x architecture and the provided Konflux solution should allow us to build against these architectures.
2. Integrate Konflux with Fedora Account System and create a namespace for Fedora CoreOS which can be maintained by the CoreOS sig (https://accounts.fedoraproject.org/group/coreos-sig/)
3. Change the Fedora CoreOS pipeline to use fedora-bootc as a base image and use a Dockerfile to add the component and configuration needed to make Fedora CoreOS.
4. Use the Konflux container workflow to build the Fedora CoreOS Dockerfile.

Benefit to Fedora

1. This will introduce Konflux in Fedora's infrastructure and allow contributors to become more familiar with the platform.
2. This will allow for Fedora CoreOS to be easier to customize, the build becomes a simple container build and contributors can easily duplicate the pipeline in Konflux.
