Docker Mastery

Docker Mastery is a standalone skill that teaches any OpenClaw agent how to containerize applications, write production Dockerfiles, manage multi-service environments with Compose, and deploy containers reliably — not just running hello-world, but building images that are secure, small, and fast for real applications. Most agents can write a basic Dockerfile. This skill teaches them to build the containerization pipeline that gets code from laptop to production.

Drop this skill into any OpenClaw persona's skills folder and your agent immediately knows how to write multi-stage Dockerfiles, configure Docker Compose for full-stack environments, debug container issues, deploy with zero downtime, and set up CI/CD pipelines that build and ship automatically.

🐳 Everything Included This skill covers the full Docker lifecycle — no separate purchases needed:

Dockerfile Patterns — multi-stage builds, layer caching, security hardening, and health checks for Node.js, Python, and Next.js applications Docker Compose — multi-service orchestration with databases, caches, reverse proxies, and proper dependency management CLI Operations — image, container, volume, and network management from the command line Deployment Patterns — VPS deployment, zero-downtime updates, and GitHub Actions CI/CD pipelines Debugging — diagnosing container startup failures, network issues, and image bloat

Proven patterns:

Multi-stage builds that cut image size by 80% while keeping builds fast Layer ordering that maximizes cache hits so rebuilds take seconds, not minutes Health checks that let Docker and orchestrators know when your app is actually ready Compose configurations for full-stack environments that start with one command

What makes this different from Docker tutorials:

Production-grade patterns — Dockerfiles that are secure, small, and properly configured for real deployments Full Compose examples — not just app + database, but app + database + cache + reverse proxy with health checks and proper networking Deployment pipelines — GitHub Actions CI/CD that builds, pushes, and deploys automatically Debugging methodology — systematic approach to the most common Docker problems Agent-native — structured for LLM consumption so your agent containerizes projects autonomously Anti-patterns included — the 8 most common Docker mistakes that cause large images, security issues, and data loss

Includes SKILL.md with complete Docker documentation covering Dockerfiles, Compose, CLI operations, deployment, debugging, and anti-patterns. Designed for OpenClaw. Works with any persona that needs to containerize or deploy applications.
