# ─── Docker cluster ──────────────────────────────────────────────────────────

## build-docker: Build the Docker image
build-docker:
	docker compose build

## up: Start the 10-node cluster (detached)
up:
	docker compose up -d

	@echo "  Stop cluster: make down"

## down: Stop and remove all cluster containers (HyDFS volumes are kept)
down:
	docker compose down

## reset: Stop the cluster and wipe HyDFS state, then start fresh
## (exactly-once state persists in volumes; reset before re-running a demo)
reset:
	docker compose down -v

## logs: Tail logs from all nodes
logs:
	docker compose logs -f

## restart: Rebuild image and restart cluster

# ─── Demo & testing ──────────────────────────────────────────────────────────

## demo: Run the end-to-end demo pipeline (filter + count)
demo:
	@./scripts/local/run_demo.sh

## test: Run smoke test — verify cluster is up and all 10 nodes joined
test:
	@echo "Checking cluster membership (via node1 client port)..."
	@docker exec node1 sh -c 'echo "list_mem" | nc -w 3 localhost 8003'
