Dockerfile Generator

Generates production-ready Dockerfiles with multi-stage builds, security hardening, and layer optimization baked in. It walks through requirements gathering, consults local references for best practices, creates the Dockerfile and dockerignore, then validates with dockerfile-validator and iteratively fixes errors. Works across Node.js, Python, Go, and Java with language-specific templates. The deterministic workflow is refreshingly explicit: six stages with defined stop conditions and a three-iteration cap on fixes. You get non-root users, minimal base images, and proper cache layering without hunting through Docker docs. Good for new projects or cleaning up existing Dockerfiles that have grown organically messy.

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
