Why Use This Tool?

  • Containerizing Applications: Generate multi-stage build Dockerfiles without memorizing complex syntax.
  • Docker Compose Orchestration: Configure multi-container setups (Web app + Database + Redis cache) effortlessly.
  • Production Best Practices: Includes non-root user setup, minimal Alpine base images, and `.dockerignore` templates.

How to Use

  1. Select Tech Stack (Node.js, Python, Go, PHP, Static HTML/Nginx).
  2. Configure environment ports, database services (Postgres/MySQL/Redis), and environment variables.
  3. Copy generated `Dockerfile` and `docker-compose.yml` code.

Real Working Example

Input:

Stack: Node.js (Alpine) | Port: 3000 | Services: PostgreSQL + Redis

Output Result:

Dockerfile:
FROM node:18-alpine
WORKDIR /app
COPY package*.<a href="https://www.json.org/json-en.html" target="_blank" rel="noopener noreferrer" class="text-indigo-600 dark:text-indigo-400 font-semibold hover:underline" title="Learn more about JSON on official docs">json</a> ./
RUN npm ci...
EXPOSE 3000
CMD ["npm", "start"]

Is it free?

Yes, 100% free.

Can I download the generated Dockerfile?

Yes, copy code or download Dockerfile and docker-compose.yml files directly.
