Pantheon

This flake serves as a monorepo for my systems (using IaC), dotfiles, and scripts. It's hosted at https://git.rrv.sh/rrvsh/pantheon, and mirrored to https://github.com/rrvsh/pantheon.

Structure

The system configurations are defined in flake.manifest. flake.manifest.owner provides the attributes for the administrator user, including username and pubkey. flake.manifest.hosts provides the specifications for the system configurations that should be exposed by the flake as nixosConfigurations. flake.modules.nixos.* provide NixOS options and configurations. The attribute flake.modules.nixos.default provides options that will be applied to every system of that class. You can use it as seen here:

flake.modules.nixos.default.imports = [ inputs.home-manager.nixosModules.default ];

The other attributes under flake.modules.nixos should be opt-in, i.e. provide options that will be set in the profiles. flake.profiles.nixos provides profiles which use the options defined in flake.modules.nixos to define different roles for each system, such as graphical, laptop, headless, etc. Options should not be defined here. flake.contracts.nixos.* will provide contracts, such as reverse proxies or databases, which will configure options on the provider and receiver host.
