Koji Content Generators
A Koji Content Generator is an external service that generates content (jars, zips, tarballs, .npm, .wheel, .gem, etc) which is then passed to Koji for management and delivery to other processes in the release workflow. Content Generators can evolve independently of the Koji codebase, enabling the build process to be more agile and flexible to changing requirements and new technologies, while allowing Koji to provide stable APIs and interfaces to other processes.
Along with the content to be managed by Koji, a Content Generator will provide enough metadata to enable a reasonable level of auditing and reproduceability. The exact data provided and the format used is being discussed, but will include information like the upstream source URL, build tools used, build dependencies, and any container/virtualization technologies used.
The intention is that a team dedicated to managing a specific content type will design and maintain their own Content Generator, in coordination with the Koji developers. Once the Content Generator is ready for production use it will be given permission to import content and metadata it produces into Koji. Policies on the Koji hub will validate imported content and metadata and ensure that it is complete and consistent.
