# SERVER
|
|
|
|
## Overview
|
|
|
|
This document describes the architecture and setup of the self-hosted **NixOS server**, which is securely accessible via **Tailscale**. The server is designed for private, secure, and easily manageable self-hosting of various services.
|
|
|
|
|
|
|
|
## **Why This Setup?**
|
|
|
|
- **Private & Secure**: Services are only accessible through Tailscale, preventing exposure to the public internet.
|
|
- **Domain-based Access**: A custom domain (`example.org`) maps to the server's Tailscale IP, making service access simple and consistent.
|
|
- **Automatic SSL Certificates**: Using DNS-01 challenges, valid SSL certificates are generated even though the services are not publicly exposed.
|
|
- **Modular & Declarative**: Everything is managed through NixOS modules, ensuring reproducibility and easy configuration.
|
|
|
|
## **Self-Hosted Services**
|
|
|
|
The server hosts several key applications:
|
|
|
|
### **Core Infrastructure**
|
|
|
|
- **NGINX**: Reverse proxy for routing traffic to services via `example.org`.
|
|
- **Bitwarden**: A self-hosted password manager for secure credential storage.
|
|
- **Nextcloud**: A private cloud solution for file synchronization and collaboration.
|
|
|
|
### **Networking & Security**
|
|
|
|
- **AdGuard Home**: A self-hosted DNS ad blocker for network-wide ad and tracker filtering.
|
|
|
|
### **Monitoring & Storage**
|
|
|
|
- **Glance**: An awesome dashboard! (See the screenshot above)
|
|
- **Hoarder**: A self-hostable bookmark-everything app (links, notes and images)
|
|
|
|
### **Media & Content Management**
|
|
|
|
- **Arr Stack (Radarr, Sonarr, etc.)**: Automated media management tools for handling movies and TV shows. (legaly ofc)
|
|
|
|
## **How It Works**
|
|
|
|
1. **Domain Configuration**
|
|
- `example.org` is pointed to the Tailscale IP of the server. (cloudflare A record, not proxied)
|
|
- This allows for easy access without exposing services to the internet.
|
|
|
|
2. **SSL Certificate Generation**
|
|
- Certificates are obtained using a **DNS-01 challenge**, verifying domain ownership without requiring public access.
|
|
|
|
3. **NGINX Reverse Proxy**
|
|
- Routes incoming requests from `*.example.org` to the correct internal service.
|
|
- Ensures SSL termination and secure connections.
|
|
|
|
4. **Access Control**
|
|
- Only devices within the Tailscale network can reach the services.
|
|
- Firewall rules restrict access further based on necessity.
