How Your AI Homelab Works

Welcome to your AI-powered homelab! This guide explains how all the components work together to create a production-ready, self-managing infrastructure. Don't worry if it seems complex at first - the AI assistant handles most of the technical details for you.

Quick Overview

Your homelab is a Docker-based infrastructure that automatically:

• Provides secure HTTPS access to all services
• Manages user authentication and authorization
• Routes traffic intelligently
• Updates itself
• Backs up your data
• Monitors system health

Everything runs in containers - like lightweight virtual machines - that are orchestrated by Docker Compose and managed through the Dockge web interface.

Core Components

🏠 Homepage Dashboard (https://home.yourdomain.duckdns.org)

Your central hub for accessing all services. Think of it as the "start menu" for your homelab.

• What it does: Shows all your deployed services with quick links
• AI Integration: The AI can automatically add new services and configure widgets
• Customization: Add weather, system stats, and service-specific widgets
• Configuration: docker-compose/dashboards/ | service-docs/homepage.md

🐳 Dockge (https://dockge.yourdomain.duckdns.org)

Your primary management interface for deploying and managing services.

• What it does: Web-based Docker Compose manager
• Stacks: Groups services into logical units (media, monitoring, productivity)
• One-Click Deploy: Upload compose files and deploy instantly
• Configuration: docker-compose/infrastructure/ | service-docs/dockge.md

🔐 Authelia (https://auth.yourdomain.duckdns.org)

Your security gatekeeper that protects sensitive services.

• What it does: Single sign-on (SSO) authentication
• Security: Two-factor authentication, session management
• Smart Bypass: Automatically bypasses auth for media apps (Plex, Jellyfin)
• Configuration: docker-compose/core/ | service-docs/authelia.md

🌐 Traefik (https://traefik.yourdomain.duckdns.org)

Your intelligent traffic director and SSL certificate manager.

• What it does: Reverse proxy that routes web traffic to the right services
• SSL: Automatically obtains and renews free HTTPS certificates
• Labels: Services "advertise" themselves to Traefik via Docker labels
• Configuration: docker-compose/core/ | service-docs/traefik.md

🦆 DuckDNS

Your dynamic DNS service that gives your homelab a consistent domain name.

• What it does: Updates yourdomain.duckdns.org to point to your home IP
• Integration: Works with Traefik to get wildcard SSL certificates
• Configuration: docker-compose/core/ | service-docs/duckdns.md

🛡️ Gluetun (VPN)

Your download traffic protector.

• What it does: Routes torrent and download traffic through VPN
• Security: Prevents ISP throttling and hides your IP for downloads
• Integration: Download services connect through Gluetun's network
• Configuration: docker-compose/core/ | service-docs/gluetun.md

How Services Get Added

The AI Way (Recommended)

1. Tell the AI: "Add Plex to my media stack"
2. AI Creates: Docker Compose file with proper configuration
3. AI Configures: Traefik routing, Authelia protection, resource limits
4. AI Deploys: Service goes live with HTTPS and SSO
5. AI Updates: Homepage dashboard automatically

Manual Way

1. Find Service: Choose from 50+ pre-configured services
2. Upload to Dockge: Use the web interface
3. Configure: Set environment variables and volumes
4. Deploy: Click deploy and wait
5. Access: Service is immediately available at https://servicename.yourdomain.duckdns.org

Network Architecture

Internal Networks

• traefik-network: All web-facing services connect here
• homelab-network: Internal service communication
• media-network: Media services (Plex, Jellyfin, etc.)
• VPN Networks: Download services route through Gluetun

External Access

• Port 80/443: Only Traefik exposes these to the internet
• Domain: *.yourdomain.duckdns.org points to your home
• SSL: Wildcard certificate covers all subdomains automatically

Storage Strategy

Configuration Files

• Location: /opt/stacks/stack-name/config/
• Purpose: Service settings, databases, user data
• Backup: Included in automatic backups

Media & Large Data

• Location: /mnt/media/, /mnt/downloads/
• Purpose: Movies, TV shows, music, downloads
• Performance: Direct mounted drives for speed

Secrets & Environment

• Location: .env files in each stack directory
• Security: Never committed to git
• Management: AI can help update variables

AI Features

VS Code Integration

• Copilot Chat: Natural language commands for infrastructure management
• File Editing: AI modifies Docker Compose files, configuration YAML
• Troubleshooting: AI analyzes logs and suggests fixes
• Documentation: AI keeps docs synchronized with deployed services

OpenWebUI (Future)

• Web Interface: Chat with AI directly in your browser
• API Tools: AI can interact with your services' APIs
• Workflows: Automated service management and monitoring
• Status: Currently in development phase

Lazy Loading (Sablier)

Some services start on-demand to save resources:

• How it works: Service starts when you first access it
• Benefits: Saves RAM and CPU when services aren't in use
• Configuration: AI manages the lazy loading rules

Monitoring & Maintenance

Built-in Monitoring

• Grafana/Prometheus: System metrics and dashboards
• Uptime Kuma: Service uptime monitoring
• Dozzle: Live container log viewing
• Node Exporter: Hardware monitoring

Automatic Updates

• Watchtower: Updates Docker images automatically
• Backrest: Scheduled backups using Restic
• Certificate Renewal: SSL certificates renew automatically

Security Model

Defense in Depth

1. Network Level: Firewall blocks unauthorized access
2. SSL/TLS: All traffic encrypted with valid certificates
3. Authentication: Authelia protects admin interfaces
4. Authorization: User roles and permissions
5. Container Security: Services run as non-root users

VPN for Downloads

• Purpose: Hide IP address for torrenting
• Implementation: Download containers route through VPN
• Provider: Surfshark (configurable)

Scaling & Customization

Adding Services

• Pre-built: 50+ services ready to deploy
• Custom: AI can create configurations for any Docker service
• External: Proxy services on other devices (Raspberry Pi, NAS)

Resource Management

• Limits: CPU, memory, and I/O limits prevent resource exhaustion
• Reservations: Guaranteed minimum resources
• GPU Support: Automatic NVIDIA GPU detection and configuration

Troubleshooting Philosophy

• Logs First: Every service provides detailed logs. The AI can help analyze them.
• Isolation Testing: Deploy services one at a time to identify conflicts.
• Configuration Validation: AI validates Docker Compose syntax before deployment.
• Rollback Ready: Previous configurations are preserved for quick recovery.
