Felixalbs nixos config

Contains configurations for some nixos servers, some nixos desktops and a nix-darwin host. Secrets are managed with sops-nix.

Build:

  • Build locally on another machine:
nix --extra-experimental-features "nix-command flakes" build ".#nixosConfigurations.sarek.config.system.build.toplevel"

(replace "sarek" with the hostname)

  • Build, install and switch on the actual target
nixos-rebuild switch --update-input nixpkgs --update-input unstable --no-write-lock-file --refresh --flake github+felixalbrigtsen/nixos-server-conf.git --upgrade

Services and tools

Below is a list of most of the services configured in this repo, at least the ones that are accessible to the public. It might be incomplete or out of date, but should generally describe the state of my homelab.
