docker compose -f compose.yaml config
# Pull images and start in the background:
docker compose -f compose.yaml pull
docker compose -f compose.yaml up -d
# Check status and follow logs:
docker compose -f compose.yaml ps
docker compose -f compose.yaml logs -f
# Stop and remove (named volumes are kept):
docker compose -f compose.yaml down

FAQ
How do I run this Node.js Docker Compose file?
Save it as compose.yaml, then run `docker compose up -d`. Validate first with `docker compose config` and follow logs with `docker compose logs -f`.
Do I need a version field in the Node.js Compose file?
No — modern Docker Compose does not require a top-level version field, and this example does not include one.
How do I customize this Node.js template?
Open it in the free Docker Compose Generator to change images, ports, volumes, networks, environment variables, and health checks visually, then download your compose.yaml.
