About this tool
Generate production-ready Dockerfiles with multi-stage builds, security best practices, and optimized layer caching. Choose from 6 project templates: Node.js/Next.js (with standalone output), Node.js/Express, Python/FastAPI, Go, Rust, and Static Site (Nginx). Each template includes multi-stage builds to minimize image size (separating build dependencies from runtime), non-root user creation for security, health checks for container orchestration, and proper COPY ordering for optimal Docker layer caching. Edit the generated Dockerfile directly in the tool to customize it for your project. The templates follow Docker best practices including specific version tags, minimal base images (Alpine), and .dockerignore recommendations.
