This was originally presented at KubeCon North America in Chicago, and is hosted on the CNCF's Channel here. API Machinery Dual Maintainer Track — Federico Bongiovanni & Leila Jalali, Google; Stefan Schimanski, Upbound We will have 2-topic session: The first half: Introduction & SIG Overview The second half: A) Generic Control Planes, B) Ratcheting CRD Validation Join us for an informative talk! In the first half of the presentation, you'll delve into the world of API Machinery, gaining valuable insights into the opportunities available to you to start your contributions to our projects. Then, we learn more about Generic Control Planes and Ratcheting CRD Validation. Introduction & SIG Overview (Leila Jalali) Leila will cover a comprehensive overview about the SIG: Where are we on the journey? Introduction & SIG Overview What do we own? Why is it so important and complex? Roadmap Generic API Server Roadmap (Stefan Schimanski) Stefan will highlight developments in Sig-API-Machinery that fly under the radar of big new feature work in Kubernetes, but that will have an impact on how the ecosystem is building Kubernetes extensions. In particular, generic control planes will be discussed and automatic and explicit ratcheting validation. The latter will make CRD schema evolution dramatically easier, and everybody shipping CRDs should know about what's coming.
