Simplify Kubernetes Operator Development With a Modular Design Pattern
Talkat KubeCon + CloudNativeCon Europe 2025 · on Thursday, 2025-04-03· at 14:15· Level 1 | Hall Entrance N10 | Room F·
summary
Presents a concrete design: split large CRDs into smaller trait CRDs and replace monolithic controllers with focused microcontrollers coordinated by a lightweight orchestrator, while delegating CRD-to-manifest translation to a Helm-driven trait system. Shows mapping examples (size → replicas: small=1, medium=2, large=3), calls out the pain of using the unstructured API, and reports a working implementation in the ACDA project powering AI stream processing pipelines for the Netherlands water sector, reducing controller code and speeding iteration.
