Practical Way to Build Kubernetes Native Java Controller

summary
A Java-native controller runtime ports Kubernetes controller primitives onto the official Java client, implementing Informer/store/queue/leader-election so Java teams can write reconciler classes, wire controllers with a builder and run them under a manager. The framework highlights practical wins: heap dumps and richer GC/thread diagnostics, generics-based APIs, and production deployment at Ant Financial. Gaps include some informer parity and memory tuning for very large clusters and planned moves to OpenAPI v3 and a custom object serializer.
