I use NixOS as the base operating system for my Homelab. Its declarative nature ensures that my system configuration is reproducible and version-controlled.

Core Configuration

The entire system state is defined in /etc/nixos/configuration.nix.

Key Features

1. Tailscale:
   • Configured directly via the system config (services.tailscale.enable = true;).
   • Provides a secure mesh VPN to access the server remotely without opening ports.
2. Containerization:
   • Docker is enabled at the system level (virtualisation.docker.enable = true;) to support my Homelab stack.
3. User Management:
   • Users, groups, and SSH keys are managed declaratively, preventing "configuration drift."
4. Auto-Updates:
   • System updates and garbage collection are automated to keep the host clean.
