Docker Compose Secure Generator

What problem does it solve?

Insecure Docker Compose configurations are a major attack vector, leading to server compromises due to publicly exposed ports, privileged containers, and hardcoded secrets. This Skill prevents these common pitfalls, safeguarding your applications and infrastructure.

Core Features & Use Cases

• Default Localhost Port Binding: Automatically binds all ports to 127.0.0.1 by default, preventing accidental public exposure.
• Least Privilege Enforcement: Includes no-new-privileges:true and recommends non-root users and read-only filesystems.
• Resource & Health Management: Adds resource limits, health checks, and logging configurations to prevent resource exhaustion and ensure service stability.
• Use Case: Generate a secure docker-compose.yml for a new web application, database, and Redis cache, ensuring all services are isolated, have proper health checks, and are not publicly exposed by default.

Quick Start

Generate a secure Docker Compose file for a Node.js application, a PostgreSQL database, and a Redis cache. Ensure the Node.js app is exposed on port 3000 (localhost only) and the database is on an internal network.
