Dockerfile Generator

Pick a language/runtime to generate a basic Dockerfile boilerplate. Tweak it further to fit your project.

Writing a Dockerfile from scratch every time you containerize a new project gets old. This gives you a quick starting point for common stacks (Node/Python/Go) that you can adjust from there.

# Use Cases

  • Containerizing an existing Node/Python/Go project for the first time and wanting a starting point
  • Quickly producing several similar Dockerfiles that only differ in WORKDIR or the EXPOSE port
  • Showing a new team member the basic shape of a Dockerfile (FROM/WORKDIR/COPY/CMD)

# Usage

  1. Choose a base image (language/runtime).
  2. Adjust WORKDIR and the EXPOSE port as needed.
  3. Copy the generated Dockerfile and fine-tune it for your project.
FROM node:20-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --omit=dev
COPY . .
EXPOSE 3000
CMD ["node", "index.js"]

# FAQ

Is this ready for production as-is?
It's a minimal starting point. Multi-stage build optimization, running as a non-root user, health checks, and other concerns need additional attention for production use.
Is this an official Docker or vendor tool?
No, this is an independent, unofficial generator — not affiliated with Docker, Inc. or any language's official tooling.
