docker-sandbox

What This Skill Does

The docker-sandbox skill provides a high-level orchestration layer for creating, managing, and interacting with isolated Virtual Machine environments powered by Docker Desktop. It acts as a security wrapper, allowing OpenClaw agents to perform potentially sensitive operations—such as executing arbitrary code, installing experimental npm packages, or parsing untrusted data files—without exposing the host machine's filesystem or network credentials to risk. By utilizing virtiofs for performant workspace mounting and integrated network proxy controls, this skill ensures that agents operate within a strictly defined perimeter.

Installation

To install this skill, use the ClawHub CLI command from your terminal: clawhub install openclaw/skills/skills/gitgoodordietrying/docker-sandbox Ensure you have Docker Desktop 4.49 or later installed. Verify your setup by running docker sandbox version to confirm the plugin is active and ready for your OpenClaw agents.

Use Cases

• Security Sandboxing: Running untrusted open-source libraries or scripts downloaded from the web without fear of system-level compromise.
• Environment Consistency: Eliminating 'it works on my machine' issues by creating immutable, reproducible dev environments for specific agent tasks.
• Destructive Testing: Running scripts that modify system configurations or perform heavy cleanup operations that you would not want to execute on your local host.
• Network Auditing: Using the built-in proxy controls to restrict an agent's network traffic to specific allowed domains, perfect for testing API integrations in a controlled setting.

Example Prompts

1. "Create a new sandbox named 'test-env' using the claude agent in my current directory, then install the latest version of express inside it."
2. "Run the agent in my current sandbox to analyze the codebase for security vulnerabilities, but ensure it is blocked from accessing any external domains except for npmjs.com."
3. "Spin up a clean environment for my project and execute 'npm run test' to ensure all my build scripts work in an isolated state."

Tips & Limitations

• Persistence: By default, removing a sandbox destroys the VM. Use docker sandbox save to persist your configuration as a template for future tasks.
• Performance: While virtiofs is fast, massive file trees can impact initial mounting times. Keep project subdirectories lean if possible.
• Isolation: Remember that while this tool provides significant isolation, it is not a 'firewall for malicious intent.' Always review proxy allowlists before executing unknown code.
