Who am I? Langdon White Formerly Evangelist for RHEL Platform Architect Working on Fedora Modularity

Rings proposal Fedora.next & Fedora Rings

Starting the solution Don't forget about cloud-atomic Fedora Editions

Rings Don’t work Different user scenarios have different risks

What we are doing and how Aleph: Kind of rings (sets really) for numbers a-0 = integers, a-1 = ordinal numbers, etc What we are doing and how

What is a module? A thing that is managed as a logical unit A thing that promises an external, unchanging, API A thing that may have many, unexposed, binary artifacts to support the external API A module may “contain” other modules and is referred to as a “module stack”

Base Runtime (Module Stack)

modulemd: Describe a module

Progress Established the Modularity WG, subsumed Envs & Stacks and Base WGs Implemented a dnf plugin Implemented an alpha version of the module build pipeline Implemented an alpha of the pipeline visualization Ability to “coalesce” modules for testing Kicked off Base-Runtime
