Beyond Kubebuilder - Generating Entire Kubernetes Controller Implementations
Talkat KubeCon + CloudNativeCon North America 2022 · on Wednesday, 2022-10-26· at 15:25· Portside Ballroom (Room 260)·
summary
Built a Kubernetes controller factory that consumes AWS API models and a generator.yaml to output full controllers (not just scaffolds), mapping AWS SDK Go types to CRs with generated SDK bind code and generated delta comparators to detect changes. Uses kubebuilder/controller-gen/controller-runtime for types and a common reconcile runtime plus a resource manager interface (create read update delete methods). Produces images, Helm charts and OLM artifacts automatically; 21 published controllers, ~80–98% generated, over a million lines of generated code, ~2% handwritten for edge cases.
