Detailed Description
Several Fedora images are being built by the Red Hat Image Builder service (Fedora IoT, Fedora Minimal). Image Builder acts as a content generator in Koji. Images are built external to Fedora infrastructure as requested by Koji and then delivered back.
This has led to of issues over time. Amongst them instability and the inability of Fedora release engineering and infrastructure teams to intervene and the inability to freeze the external infrastructure during a release window.
I plan to replace the current approach in koji-osbuild with a local-only build. Image Builder machinery and definitions will still be used for the mentioned images but the build will run locally on Fedora infrastructure and builders. In the same way that kiwi or livemediacreator-images are built.
My plan is to start with adding these tasks to koji-osbuild, keeping them there for a cycle and if they are stable to upstream them into koji directly; deprecating koji-osbuild at that point in the future.
image-builder-cli built images can be easily rebuilt locally from their manifests uploaded in koji. The images can be easily built locally and support all end-user customizations available. Work is ongoing in the Image Builder stack to also move the definitions of the distribution to a declarative format.
Feedback
This change proposal does not yet provide a way for the distribution definitions to be owned by, and live inside, Fedora infrastructure. I plan to address this in a later change proposal.
Benefit to Fedora
Control over Image Builder on its own infrastructure, lessen remove the need to reach out to external parties when releases are blocked.
Scope
Proposal Owners
- Submit the
image-builder-clipackage for inclusion in Fedora 42. - Request a
image-builder-buildcomp group for the build requirements in koji roots. - Change the
koji-osbuildplugin to provide a new task type that usesimage-builder-cli.
- Changes to pungi to be able to schedule these tasks.
- Changes to pungi config for Fedora IoT.
- Changes to pungi config for Fedora Minimal.
Contingency Plan
Independent of where on the above tasks I get stuck images can continue to be built with the current setup.
