Creating a Kubernetes Operator in Java
summary
Shows a concrete Java operator proof‑of‑concept using the fabric8 Java client to talk to the Kubernetes API, registering a custom resource Domain (dpr.fish/v1) and running as a pod in‑cluster. It installs watcher callbacks to receive add/modify/delete events, programmatically creates deployments and services, executes init scripts inside pods, and brings up a domain server plus two instances (three pods total). Works end‑to‑end as a POC but application deployment and load‑balancer wiring remain unfinished.
