# krops (krebs ops) krops is a lightweigt toolkit to deploy NixOS systems, remotely or locally. ## Some Features - store your secrets in passwordstore - build your system remotely - minimal overhead (it's basically just `nixos-rebuild switch`!) - run from custom nixpkgs branch/checkout/fork ## Minimal Example Create a file named `krops.nix` (name doesn't matter) with following content: ``` let krops = (import {}).fetchgit { url = https://cgit.krebsco.de/krops/; rev = "3022582ade8049e6ccf18f358cedb996d6716945"; sha256 = "0k3zhv2830z4bljcdvf6ciwjihk2zzcn9y23p49c6sba5hbsd6jb"; }; lib = import "${krops}/lib"; pkgs = import "${krops}/pkgs" {}; source = lib.evalSource [{ nixpkgs.git = { ref = "4b4bbce199d3b3a8001ee93495604289b01aaad3"; url = https://github.com/NixOS/nixpkgs; }; nixos-config.file = toString (pkgs.writeText "nixos-config" '' { pkgs, ... }: { fileSystems."/" = { device = "/dev/sda1"; }; boot.loader.systemd-boot.enable = true; services.openssh.enable = true; environment.systemPackages = [ pkgs.git ]; } ''); }]; in pkgs.krops.writeDeploy "deploy" { source = source; target = "root@192.168.56.101"; } ``` and run `$(nix-build --no-out-link krops.nix)` to deploy the target machine. Under the hood, this will make the sources available on the target machine below `/var/src`, and execute `nixos-rebuild switch -I /var/src`. ## References - [In-depth example](http://tech.ingolf-wagner.de/nixos/krops/) by [Ingolf Wagner](https://ingolf-wagner.de/)
