Getting Started

Welcome to the Enterprise Homelab documentation! This guide will help you understand, deploy, and manage a sophisticated 28-container infrastructure using modern GitOps practices.

🎯 What You'll Learn

This documentation covers everything needed to build and operate an enterprise-grade homelab:

• Infrastructure as Code using Terraform and Ansible
• Advanced Monitoring with Prometheus, Grafana, Loki, and AlertManager
• GitOps Workflows with automated deployment and rollback capabilities
• Container Orchestration across 28 specialized services
• Security Best Practices including network segmentation and VPN access

📋 Prerequisites

Before getting started, ensure you have:

Hardware Requirements

• Proxmox VE 8.14+ cluster with sufficient resources
• Minimum 32GB RAM (current allocation: 30.75GB)
• 10TB+ storage for media and data
• Dual network interfaces for VPN routing (optional)

Software Requirements

• Terraform >= 1.6.0
• Ansible >= 2.15.0
• Git with SSH key configuration
• Basic knowledge of Linux, containers, and networking

Access Requirements

• Proxmox API access with appropriate permissions
• GitHub account for repository hosting and CI/CD
• Domain name (optional, for SSL certificates and external access)

🚀 Quick Start Options

Choose your preferred approach:

Option 1: Full Deployment

Deploy the complete 28-container infrastructure from scratch using the GitOps workflow.

👉 Start Full Deployment

Option 2: Selective Deployment

Deploy specific service categories (media, monitoring, security, business) based on your needs.

👉 Choose Services

Option 3: Learning Mode

Explore the architecture and understand the GitOps implementation without deploying.

• Troubleshooting and maintenance guides

⚡ Quick Commands Reference

Essential commands for managing your homelab:

# Infrastructure Management
terraform plan    # Preview infrastructure changes
terraform apply   # Apply infrastructure changes
terraform destroy # Remove infrastructure (careful!)

# Configuration Management  
ansible-playbook -i inventory playbooks/site.yml  # Deploy all services
ansible-playbook -i inventory playbooks/monitoring.yml  # Deploy monitoring only

# Service Management
systemctl status docker  # Check Docker service
docker ps -a            # List all containers
docker logs container   # View container logs

# Monitoring
curl -s http://localhost:9090/metrics | head  # Check Prometheus
journalctl -f -u docker                       # Follow Docker logs

🎯 Next Steps

1. Review Prerequisites - Ensure your environment meets requirements
2. Choose Deployment Method - Full, selective, or learning mode
3. Follow Installation Guide - Step-by-step deployment process
4. Configure Monitoring - Set up observability and alerting
5. Customize Services - Adapt configurations to your needs

💡 Best Practices

Keep these principles in mind:

• Infrastructure as Code: All changes should go through version control
• Documentation: Update docs when making infrastructure changes
• Testing: Use staging environments for significant changes
• Monitoring: Implement comprehensive observability from day one
• Security: Follow least-privilege and network segmentation principles
• Automation: Automate repetitive tasks and maintenance procedures

🆘 Getting Help
