Dockerfile Generator
Generate a Node.js Dockerfile (optional multi-stage, non-root) with version, port, and start command. Everything is processed on your device, nothing is sent to a server.
Everything runs in your browser. Your data is never sent to our servers.

About Dockerfile Generator
Dockerfile Generator builds a ready-to-use Dockerfile for a Node app. You pick the Node version (alpine), package manager, port, start command, and whether to use a multi-stage build.
A multi-stage build separates the build stage from the runtime so the final image is much smaller. The USER node directive runs the container as non-root for security.
FAQ
Is my data sent to a server?
No. Every file is generated in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers.
Is the output ready to use?
Yes. The output is a valid, ready-to-commit config/deployment file. Always adjust the defaults (port, domain, passwords) for your environment before production.
