Docker Compose

What This Skill Does

The Docker Compose skill enables the OpenClaw agent to architect, manage, and optimize multi-container environments. It provides deep technical guidance on service orchestration, including configuring robust health checks, managing inter-service dependencies, and optimizing volume persistence. This skill transforms your agent into a DevOps assistant capable of writing production-ready YAML configurations that handle networking, resource constraints, and build context security.

Installation

To integrate this skill into your environment, use the OpenClaw CLI: clawhub install openclaw/skills/skills/ivangdavila/docker-compose

Use Cases

• Production Orchestration: Converting development environments into stable production configurations using multi-file override patterns.
• Performance Tuning: Applying strict resource limits (limits: memory) to prevent container sprawl and host-resource exhaustion.
• Lifecycle Management: Safely managing volume lifecycles to prevent catastrophic data loss during cleanup commands.
• Security Hardening: Implementing .dockerignore strategies to keep sensitive artifacts and bulky dependencies out of images.
• Environment Segregation: Utilizing Profiles to toggle between dev-only debugging tools and essential production services.

Example Prompts

1. "Analyze my docker-compose.yml and suggest a healthcheck configuration for my Postgres service so that my web app waits for it to be fully ready before starting."
2. "I am seeing slow build times; can you help me create a .dockerignore file and explain how to optimize my build context?"
3. "How can I set up my project to use an override file so that I don't accidentally expose ports or mount local volumes in my production deployment?"

Tips & Limitations

• Dependency Readiness: Remember that depends_on only manages startup order. Always pair it with service_healthy conditions and a properly tuned start_period for databases and Java apps to ensure the service is actually queryable.
• Volume Safety: Avoid the habitual use of docker compose down -v. This flag deletes named volumes and causes permanent data loss. Always verify your volumes before destruction.
• Precedence Awareness: Debug your environment variables using docker compose config to see how the system resolves conflicts between shell variables, .env files, and environment: declarations.
• Limits: Always define resource limits in development to uncover potential memory leaks early. If a service crashes under a limit in dev, it is better to fix the code now than to experience an OOM kill in production.
• Overrides: Keep your base configuration minimal. Use docker-compose.override.yml for local developer-specific tweaks and custom files for deployment variations.
