Building an Edge Control Plane with Kubernetes and Envoy
summary
Ambassador is an edge control plane that wires Kubernetes resources into Envoy by generating global Envoy config, moving from a REST+DB prototype to storing state in Kubernetes annotations and CRDs. The project grows to thousands of active installations with 7,000 commits from 70 contributors, then undergoes a grand refactor: the Jinja2 template engine is replaced by a multi‑pass compiler and Envoy is migrated to Envoy v2 and xDS enabling live updates, new features and easier external contributions while tests and TLS edge cases remain the biggest pain.
