nixos-servers

Nix definitions to configure our physical servers. Currently, only one physical server (named jefke) is implemented but more are planned!

Additional documentation

Prerequisites

  1. Install the Nix package manager or NixOS (link)
  2. Enable flake and nix commands (link)
  3. Install Direnv (link)
  4. Allow direnv for this repository: direnv allow

Bootstrapping

We bootstrap our physical server using nixos-anywhere. This reformats the hard disk of the server and installs a fresh NixOS. Additionally, it deploys an age identity, which is later used for decrypting secrets.

⚠️ This will wipe your server completely ⚠️

  1. Make sure your have a Secret service running (such as Keepassxc) that provides the age identity.
  2. Ensure you have root SSH access to the server.
  3. Run nixos-anywhere: ./bootstrap.sh <servername> <hostname>

Deployment

To deploy all servers at once: deploy To deploy only one server: deploy --targets .#<host>
