SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It prevents AI-generated Dockerfiles from being insecure, non-deterministic, and inefficient by enforcing production-grade Dockerfile conventions that avoid common CI and runtime failures.

Core Features & Use Cases

  • Production-grade Dockerfile structure: Multi-stage builds that keep runtime-only artifacts in the final image.
  • Reproducible and secure dependency handling: Pinned base images, cache-friendly COPY ordering, and secret mounts instead of baking secrets into layers.
  • Operational correctness: Non-root execution, exec-form CMD for proper signal handling, and required .dockerignore hygiene to keep builds fast and consistent.
  • Works across common stacks: Node, Go, Rust, and Python defaults, with worked Dockerfile examples and a dedicated verifier script.

Quick Start

Use the Dockerfile verifier to check your Dockerfile at skills/infra/forge-dockerfile/verify/check_dockerfile.sh and fix any violations it reports.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a secure Dockerfile with multi-stage builds for production?

Secure Dockerfiles use multi-stage builds to isolate runtime artifacts, enforce pinned base image tags, and reject baked-in secrets to ensure deterministic CI builds and safe production pulls.

What is the correct way to handle secrets in a Dockerfile?

Handling secrets in a Dockerfile requires using secret mounts instead of baking sensitive data into image layers, explicitly rejecting secret-shaped ENV or COPY instructions to prevent runtime exposure.

Does this Dockerfile generator work with Python and Go services?

Yes, this Dockerfile generator provides containerization defaults and worked examples for Node, Go, Rust, and Python services, applying correct signal behavior and non-root execution across these stacks.

Why does my Docker build fail due to exec-form CMD and signal handling?

Docker builds fail with signal handling issues when not using exec-form CMD, which is required to ensure proper process signal behavior and non-root execution during container runtime operations.

What is the best way to keep Docker images small and reproducible?

Keeping Docker images small and reproducible requires mandatory .dockerignore hygiene, cache-friendly COPY ordering, and version-safe package installs to optimize build speed and consistency across large-scale pulls.

How do I validate my Dockerfile against production security standards?

Validating Dockerfiles against production security standards involves running a dedicated verifier script that checks for pinned dependencies, multi-stage structures, and non-root execution to report violations.
