minecraft-prometheus-exporter

End-to-end docker-compose test harness for the minecraft-prometheus-exporter. Spins up an itzg/minecraft-server:latest vanilla server alongside a freshly built exporter and walks the user through verifying metrics in a live browser/Prometheus session. Use this skill whenever the user wants to "test the exporter end-to-end", "verify metrics against a real Minecraft server", "spin up a local MC server", "run the docker compose test", scrape /metrics from a vanilla MC server, or sanity-check a code change in this repo before opening a PR — including cases where the user just says "let me see if it works" or "run the exporter against MC" without naming the compose file.
