}In order to use dres in your NixOS please follow:
Merge following snippet with your flake.nix file:
{
inputs.hosts.url = github:cepe/dres;
outputs = { self, nixpkgs, dres, ... } @ inputs: {
nixosConfigurations.<hostname> = {
system = "<arch>";
modules = [
dres.nixosModules.default
];
};
};
}Configure dres in your configuration.nix:
{config, lib, pkgs, ...} : {
dogjam.services.dres = {
enable = true;
config = {
cidrs = {
ipv-4 = "0.0.0.0/0";
};
resolvers = {
cloudflare = {
type = "delegating";
socket = "1.1.1.1:53";
};
intranet = {
type = "static";
hosts = {
"printer.home.lab" = "10.0.0.10";
};
};
hosts-file = {
type = "hosts-file";
path = "/etc/hosts";
};
};
configuration = {
ipv-4 = [
"intranet"
"hosts-file"
"cloudflare"
];
};
};
};
