Writing Dockerfiles from scratch is error-prone. Docker init analyzes your project and generates optimized Dockerfile.
Run in Project Directory:
docker init # Detects project type (Node.js, Python, Go, etc.) # Asks questions about your app # Generates: # - Dockerfile # - .dockerignore # - docker-compose.yml
Example Output for Node.js:
Creates multi-stage build, sets up proper user permissions, configures healthcheck, optimized for production!
Supports: Node.js, Python, Go, Rust, Java, .NET, PHP
Result: Production-ready Dockerfile in 30 seconds instead of 30 minutes!
Available in Docker Desktop 4.18+ or Docker CLI 24+
