Build, optimize, and manage Docker containers — write Dockerfiles, compose stacks, and debug container issues.

Difficulty & Skill
Overview
Docker is the backbone of modern development infrastructure, but its CLI has hundreds of commands, flags, and configuration options. Building optimized images, debugging container networking, managing volumes, and writing multi-stage Dockerfiles all require deep Docker knowledge that most developers only use occasionally.
With OpenClaw and the Docker Container Manager skill, you describe what you want in plain language — "run a PostgreSQL 16 container with persistent storage on port 5433" — and get the correct Docker commands executed immediately. No more searching Stack Overflow for the right flag combination.
Beyond simple commands, the skill handles complex workflows: writing multi-stage Dockerfiles with proper layer caching, setting up Docker Compose stacks for multi-service environments, debugging containers that won't start, and cleaning up disk space from dangling images and volumes.
How It Works
- Describe your Docker task in natural language to the OpenClaw agent
- The agent translates your request into the correct Docker CLI commands
- For Dockerfiles and Compose files, it generates optimized configurations with security best practices
- Commands are executed directly — you see real-time output from Docker
- The agent interprets error messages and suggests fixes if something fails
- For cleanup tasks, it safely identifies and removes unused resources without affecting running containers
Example Scenarios
- You need a local PostgreSQL database for development — the agent sets up a container with proper volume mounts, environment variables, and port mapping in one command
- Your Docker image is 2GB — the agent rewrites your Dockerfile with multi-stage builds to reduce it to 200MB
- A container keeps restarting — the agent inspects logs, checks resource limits, and identifies the OOM kill causing the crash loop
- You need to run three services locally (API, database, Redis) — the agent generates a complete docker-compose.yml with health checks and proper networking
- Your CI builds are slow — the agent optimizes Dockerfile layer ordering to maximize cache hits
Frequently Asked Questions
Does this require Docker Desktop?
It requires the Docker CLI to be available on your system. This works with Docker Desktop, Docker Engine, OrbStack, Colima, or any Docker-compatible container runtime.
Can it manage remote Docker hosts?
Yes. If your Docker CLI is configured to connect to a remote host (via DOCKER_HOST or Docker contexts), the agent will use that connection. All commands go through your local Docker client.
Does it support Docker Compose v2?
Yes. The Docker Container Manager skill supports both the standalone docker compose (v2) command and legacy docker-compose. It auto-detects which version is available.
Is it safe to let an AI manage containers?
The skill executes Docker commands through your local shell. You see every command before and after execution. For production environments, we recommend using it with read-only access first to build confidence.
