Updated . Provided as is. Check the output before you rely on it in production.

How to use Dockerfile Generator

  1. 1

    Pick the runtime

    Choose Node, Python or Go to get the matching base image and build steps.

  2. 2

    Enter the start command

    Enter how your app starts, for example npm run start or python app.py.

  3. 3

    Review the Dockerfile

    The template uses slim or alpine base images and a non-root user; the Go version is a multi-stage build.

  4. 4

    Copy and adapt

    Copy it, add your ports and health checks, and lint it with Dockerfile Linter before production.

Questions and answers

Why a non-root user?
If the app is compromised, a non-root user limits what an attacker can do inside the container.
Is the output production-ready?
It is a safe starting point. Review it for your app's ports, build steps and health checks.

Use it as an API

Dockerfile Generator is also callable as a free HTTP JSON API at https://aidevhub.io/api/dockerfile-generator/ — GET with query parameters or POST with a JSON body, no authentication, CORS enabled, fair use (abusive traffic is throttled at the edge; there is no per-request quota header). Responses return { ok, tool, result, meta }. 

curl -s "https://aidevhub.io/api/dockerfile-generator/?start_command=npm%20run%20start&mode=node"
