dockerfile-builder
Generate production-ready, optimized Dockerfiles for multiple languages and frameworks. Supports Node.js, Python, Go, Java, and Rust with multi-stage builds, security hardening, non-root users, layer caching optimization, and .dockerignore generation. Follows Docker best practices including minimal base images, proper signal handling, health checks, and secret management.
