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.

Frequently Asked Questions about forge-dockerfile

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.
