Building a Software-Defined-Network Using K8s API Machinery and Controllers

Explore the application of Kubernetes controller patterns and API machinery in building software-defined networks (SDN) in this 39-minute conference talk. Discover how these tools, originally designed for Kubernetes, are being adapted to solve new challenges in different contexts. Learn about the lessons gained from constructing an SDN using these methods, including strategies for IP allocation without multi-object transactions, maintaining consistency between API objects, and efficiently managing dynamic informers for guest-host mapping distribution. Gain insights into applying the controller pattern to your own projects, understanding how it can simplify the creation of a reliable control plane and allow you to concentrate on problem-specific aspects. This presentation is ideal for developers and architects interested in extending Kubernetes concepts beyond container orchestration.
