LabFusion Development Progress

Project Overview

LabFusion is a unified dashboard and integration hub for homelab services, built with a polyglot microservices architecture.

Architecture Decisions

• Modular Services: Each service is independently deployable
• Polyglot: Services can use different languages (Java, Python, Go, Node.js)
• Message Bus: Redis for inter-service communication
• Database: PostgreSQL for persistent data
• Containerization: Docker for all services

Development Notes

Service Independence

Each service is designed to be:

• Independently deployable
• Language-agnostic
• Self-contained with its own dependencies
• Communicating via Redis message bus

Future Service Additions

The modular structure allows for easy addition of new services:

• Data Processing Service (Rust) - For heavy data processing
• ML Service (Python) - For machine learning features
• API Gateway v2 (Go) - For high-performance routing
• Cache Service (C++) - For high-performance caching

Phase 7: CI/CD Pipeline Setup

• Gitea Actions CI/CD (2024-12-09)
  • Complete CI/CD pipeline for polyglot microservices architecture
  • Individual service pipelines for Java, Python, Node.js, and React
  • Integration testing with PostgreSQL and Redis services
  • Local Docker builds for testing and validation
  • Security scanning with Trivy vulnerability scanner
  • Code quality gates with linting, testing, and coverage requirements
  • Comprehensive CI/CD documentation and configuration
  • Simplified pipelines focused on testing and validation

Technical Debt
