This post covers the Operator pattern (CRD + controller + reconcile loop) from first principles, then how to build a real operator with kube-rs: defining a CRD with the CustomResource derive macro, the Api and Controller types, the watcher, the reconcile function and requeue, using finalizers for cleanup logic, and why you might reach for Rust over Go/kubebuilder (small resource footprint, memory safety).

CustomResource 파생 매크로로 CRD 정의, Api와 Controller, watcher, reconcile 함수와 requeue, 파이널라이저(finalizer)로 정리 로직 처리, 그리고 왜 Go/kubebuilder 대신 Rust를 쓰는지(작은 리소스 풋프린트, 메모리 안전성)까지 살펴봅니다.
