Dockerfile Generator

Overview

This skill provides a comprehensive workflow for generating production-ready Dockerfiles with security, optimization, and best practices built-in. Generates multi-stage builds, security-hardened configurations, and optimized layer structures with automatic validation and iterative error fixing.

Key Features:

• Multi-stage builds for optimal image size (50-85% reduction)
• Security hardening (non-root users, minimal base images, no secrets)
• Layer caching optimization for faster builds
• Language-specific templates (Node.js, Python, Go, Java)
• Automatic .dockerignore generation
• Integration with dockerfile-validator for validation
• Iterative validation and error fixing (minimum 1 iteration if errors found)
• Local references plus docs lookup fallback chain for framework-specific patterns
