SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps in synthesizing component-level documentation into container-level architecture, mapping components to deployment units, and documenting container interfaces.

Core Features & Use Cases

  • Container Synthesis: Consolidates component details into deployment container definitions.
  • Interface Documentation: Documents container interfaces as APIs, including OpenAPI specifications.
  • Diagram Generation: Creates C4 container diagrams using Mermaid syntax.
  • Use Case: When designing a microservices architecture, use this Skill to document each microservice as a container, detailing its purpose, technology, interfaces, and dependencies.

Quick Start

Use the c4-container skill to document the 'user-service' container, detailing its REST API and PostgreSQL database.

FAQPage Schema
How do I document container-level architecture for a microservices deployment?

Documenting container-level architecture involves synthesizing component documentation into deployment units, mapping components to containers, and defining container interfaces as APIs with OpenAPI specifications. This process generates Mermaid container diagrams to visualize system deployment.

What is a C4 container diagram and when do I need it?

A C4 container diagram visualizes deployment units and their dependencies within a software system. You need it when mapping components to containers and documenting interfaces, providing a clear view of how deployment units interact through APIs.

How do I map API interfaces to deployment containers using OpenAPI specifications?

Mapping API interfaces to deployment containers requires defining container interfaces as REST APIs with OpenAPI specifications. This synthesizes component documentation into container definitions, detailing each deployment unit's purpose, technology, and API dependencies.

Can I generate Mermaid diagrams for visualizing system deployment architecture?

Generating Mermaid diagrams for system deployment architecture is supported by synthesizing component details into container definitions. This creates C4 container diagrams that map deployment units, interfaces, and dependencies using Mermaid syntax.

Does this approach work for documenting microservices architecture and their dependencies?

This approach works for documenting microservices architecture by treating each microservice as a container. It consolidates component details into deployment container definitions, detailing purpose, technology, REST APIs, and database dependencies.

What's the best way to consolidate component documentation into deployment units?

The best way to consolidate component documentation into deployment units is through container synthesis. This maps individual components to containers, defines their interfaces as APIs with OpenAPI specifications, and generates Mermaid container diagrams for visualization.
