NixOS Infrastructure Configuration

Note

: If you're reading this, you're either drunk me, or someone I trust with my hardware. If the latter, I love you. If the former, you need to lose weight stop drinking.

Overview

Since late May 2025, I've decided to start managing my infrastructure through NixOS. This is still a long migration process from dockerizing almost everything.

Infrastructure

All machines are named after Goetic demons:

🎮 Focalor (Gaming PC)

Hardware: AMD Ryzen 7 5800X + RTX 3070

Goal: Convert to headless NixOS host running Windows VM for gaming + local services

Planned Services:

• Local LLM hosting
• Gaming VM passthrough

🏠 Valefar (Home Server)

Hardware: AMD Ryzen 5 5600 + GTX 1650

NixOS Services:

• S3 storage via Garage, see services/garage.nix
• Forgejo, see services/forgejo.nix
• Tailscale connectivity

Docker Services (docker-compose):

• PocketID authentication
• Affine notes
• Komodo
• Valheim server
• Vaultwarden password manager
• Beszel

🍎 Gabriel

Hardware: M4 16gb Mac Mini

Services:

• Runs three github actions runners for embedder, simplelink, and simplegit

🏴‍☠️ Buer (LiteServer VPS)

Hardware: 1 core, 1GB RAM, 20TB data cap

Services:

• Headscale server
• Exit node for privacy/torrenting

Notes: DMCA-friendly provider

☁️ Elise (Oracle Cloud VPS)

Hardware: 4 Ampere ARM cores, 24GB RAM, 4TB data cap

Status: Currently on Oracle Linux, planning to rename to "Vine"

Services:

• Komodo
• Personal website
• Link shortener
• Embedder
• Minecraft server
• Reverse proxy
• Tailscale connectivity

Migration: Planned conversion to NixOS, everything is under one big docker-compose file

• exit node for headscale based in atlanta

Future Plans

Authentication & Identity Management

• LDAP Server - Centralized user directory (considering OpenLDAP or FreeIPA)
• Authentik Integration - Sync PocketID with Authentik for unified SSO across all services

Monitoring & Observability

• Advanced Uptime Monitoring - Replace basic monitoring with more comprehensive solution
  • Considering: StatusPage, Cachet, or custom Prometheus/Grafana setup
• Network Monitoring - Deep visibility into network performance and usage
  • Considering: LibreNMS, Zabbix, or PRTG alternative
• Centralized Logging - Aggregate logs from all services (Loki + Promtail)
• Metrics Collection - Unified dashboards showing health across all machines

Infrastructure Improvements

• Automated Backups - Implement 3-2-1 backup strategy across all services
• Configuration Management - Complete migration from Docker to declarative NixOS configs
• High Availability - Service redundancy and failover capabilities (especially s3, can have Garage on vine + buer)

Service Expansion

• Media Server - Jellyfin or Plex for media streaming
• CI/CD Pipeline - Automated testing and deployment for personal projects
