About this tool
Generate production-ready Dockerfiles and docker-compose.yml files for any stack. Supports Node.js, Next.js, PHP-FPM, Laravel, Python, Django, Go, and static Nginx. Options for multi-stage builds, non-root user, healthchecks, and services including MySQL, PostgreSQL, Redis, Nginx proxy, and Mailpit.
Frequently asked questions
What stacks are supported?
Node.js, Next.js, PHP-FPM (generic), Laravel, Python (FastAPI/Flask), Django with Gunicorn, Go with scratch image, and static sites served by Nginx. Each generates an opinionated, production-ready Dockerfile for that specific runtime.
What is a multi-stage build?
A multi-stage Dockerfile uses separate build and runtime stages. The first stage installs dependencies and compiles the app. The final stage copies only the compiled output, leaving behind build tools and source files. This produces significantly smaller images — often 80%+ smaller than single-stage builds.
What services can I add in Docker Compose?
MySQL (8.0, 8.4, or 5.7), PostgreSQL 16, Redis (6 or 7), Nginx reverse proxy, and Mailpit for local email testing. Each service includes a healthcheck so your app container waits for dependencies to be ready before starting.
What does the non-root user option do?
Running as root inside a container is a security risk. This option adds a dedicated low-privilege user (appuser, www-data, nextjs, or numeric UID for scratch images) and switches to it before the CMD instruction, following Docker security best practices.
What is a HEALTHCHECK instruction?
HEALTHCHECK tells Docker how to test whether your container is healthy. Docker periodically runs the check and marks the container unhealthy if it fails repeatedly. Compose uses health status for depends_on conditions so dependent services start only after dependencies are ready.
Can I generate both a Dockerfile and a Compose file at once?
Yes. Select Both in the output mode toggle at the top. Both files are generated simultaneously with matching service names, ports, and environment variables. Each has its own Copy and Download button.
