NixOS Flake

This flake allows rapid configuration of a local infrastructure. In includes:

• Generators: to generate generic machines like VM's and LXC containers, which can later be modified to handle workloads
• Hosts: to define (mostly) the workstations that need to apply their config locally
• Modules: all generic system modules that we want to re-use as much as possible
• Secrets: agenix based secrets management
• Workloads: all services we might want to run on VM's or containers

Quick start

The generators include commands and instructions to make and deploy them

• Colmena is used to deploy workloads to the generic targets.
• Use nix shell github:zhaofengli/colmena to get access to the colmena command.
• Use colmena apply to update or configure all targets.
• Use colmena apply --on <target-name> to specify which target. Use of wildcards * is allowed here.

To apply this flake to a workstation:

• Edit /etc/nixos/configuration.nix.
• Add the line nix.settings.extra-experimental-features = [ "nix-command" "flakes" ];.
• Execute sudo nixos-rebuild switch /etc/nixos.
• Clone the repo to your machine. For instance, git clone <your repo link here> ~/.nixos.
• Switch the NixOS instance to the new flake, from that repo path. For instance,sudo nixos-rebuild switch --flake .#<local hostname>
• Voila! Your NixOS instance is now configured according to the configuration cloned from the Git repo.
