How to use the Dockerfile Generator

  1. Choose your stack and version.
  2. Set the port, package manager and start command.
  3. Copy the Dockerfile and .dockerignore into your project.

What does this tool do?

The templates follow common best practice: slim or Alpine base images, dependency installation before copying source (for better layer caching), multi-stage builds that leave build tools out of the final image, and running as a non-root user. Next.js uses standalone output for a small image.

Everything runs in your browser — nothing you paste is uploaded.

Why use it?

  • Six stacks.
  • Multi-stage builds.
  • Non-root by default.

Privacy

Everything you type is processed in your browser. Nothing you enter is sent to our servers or stored by us. There's no account to create and nothing to install.
