NixOS configuration of all my computers / servers using flakes.

Currently managing configuration for 3 computers and 2 servers.

Structure is heavily inspired by Vimjoyer's videos.

I'm still new to the nix ecosystem, so you might see some slop, but it works for me.

Highlights

• Secret encryption with sops-nix
• Homelab servers configuration with k0s Kubernetes
• Daily automated flake updates with change reporting
• Epic Gnome and Thunderbird configurations
• Some custom packages

Reinstall tips

⚠️ Do not run nixos-rebuild switch --flake [...] before doing this, else nix-daemon will crash and you'll have to reboot to a previous generation!

• On the new host
  • Generate a new age key:

    nix-shell -p age
    mkdir -p ~/.config/sops/age
    age-keygen -o ~/.config/sops/age/keys.txt

  • Update the modules/system/.sops.yaml file with the new key directly in GitHub
• On an existing host
  • Run cd nixos/modules/system && sops updatekeys secrets.yaml
  • Commit & push
• On the new host
  • Pull the repo

You may now use the flake to rebuild.
