docker-compose.ymlfile.

Frequently Asked Questions
What's the difference between Dockerfile and Docker Compose?
A Dockerfile builds a single image. Docker Compose coordinates multiple containers (e.g., app + database + cache) and connects them on a shared network.
Do I need both a Dockerfile and a Compose file?
For a single-service app, a Dockerfile may suffice. For multi-service apps (like web server + database + cache), you'll want a docker-compose.yml that references one or more Dockerfiles.
Are the templates production-ready?
They provide a solid starting point. For production, you'll typically add health checks, resource limits, logging drivers, secrets management, and CI/CD integration.
What port should I use?
The templates use common default ports (e.g., 3000 for Node, 8000 for Python, 80 for Nginx). You can change the port mapping in the Compose file or the EXPOSE instruction in the Dockerfile.
