SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Safely execute code in isolation using a Docker container to prevent untrusted code from affecting the host system.

Core Features & Use Cases

  • Sandboxed execution: Runs code inside isolated containers with controlled resources.
  • Language flexibility: Supports common languages (Python, Node.js, Go, etc.) via language-specific containers.
  • Use Case: Ideal for executing user-submitted code, CI-like tasks, or experimentation without risking host integrity.

Quick Start

Run a Python snippet safely inside the sandbox by providing the code or file path.

FAQPage Schema
How do I safely run untrusted code in an isolated Docker container?▼

To safely run untrusted code in an isolated Docker container, this Skill executes scripts with strict resource caps, read-only code mounting, and automatic container cleanup to prevent host interference. It captures stdout and stderr for full auditability.

What resource limits apply when executing code in a Docker sandbox?▼

When executing code in a Docker sandbox, strict resource caps are enforced: 2 CPUs, 1 GB of RAM, and a 5-minute timeout. These deterministic resource limits prevent runaway untrusted scripts from exhausting host system resources.

Can I execute Python, Node.js, and Go scripts using Docker sandboxing?▼

Yes, you can execute Python, Node.js, and Go scripts using Docker sandboxing. This Skill supports common languages via language-specific isolated containers, enabling flexible execution of user-submitted code or CI-like tasks across multiple environments.

Does Docker-based sandboxing mount code read-only to prevent host interference?▼

Yes, Docker-based sandboxing mounts code read-only to prevent host interference. By isolating execution and enforcing read-only file mounts, the sandbox ensures untrusted scripts cannot modify the host system or escape the container boundaries.

What is the best way to capture stdout and stderr from untrusted code execution?▼

The best way to capture stdout and stderr from untrusted code execution is using a deterministic sandbox that records output streams during isolation. This Skill captures stdout and stderr securely before automatically cleaning up the Docker container.
