Krops Multi-Machine Deployment

This project deploys NixOS configurations to two machines using krops with nix-25.05.

Structure

.
├── krops.nix                      # Main deployment configuration
└── config/
    ├── machine1/
    │   └── configuration.nix      # Machine 1 NixOS config
    └── machine2/
        └── configuration.nix      # Machine 2 NixOS config

Setup

1. Update target hostnames/IPs in krops.nix:

   • Change root@machine1.example.com to your machine1 address
   • Change root@machine2.example.com to your machine2 address

2. Customize NixOS configurations in config/machine1/configuration.nix and config/machine2/configuration.nix

Usage

Deploy to a single machine:

nix-build ./krops.nix -A machine1 && ./result
nix-build ./krops.nix -A machine2 && ./result

Deploy to all machines:

nix-build ./krops.nix -A all && ./result

Requirements

• SSH access to target machines as root
• Target machines running NixOS
• nix installed on the deployment machine
