Check before installing. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

Production Docker and Kamal 2 deployment for Ruby on Rails 8 — multi-stage Dockerfile with build/runtime separation, ruby:3.x-slim over alpine (avoiding musl gotchas with nokogiri/pg/sassc), docker-compose for development with Postgres + Redis, Kamal 2 deploy.yml, zero-downtime via Kamal Proxy and the GET /up health check, secrets via Kamal envs + Rails credentials, log shipping. Use when writing or reviewing a Dockerfile for Rails, setting up Kamal, debugging deploy failures, the user mentions…

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'kamal-docker-production' ] || [ -L ~/.agents/skills/'kamal-docker-production' ]; then echo 'A skill folder named kamal-docker-production already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/09-kamal-docker-production' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/09-kamal-docker-production' ~/.agents/skills/'kamal-docker-production' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'kamal-docker-production' ~/.claude/skills/'kamal-docker-production' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
