NixOS

services-flake provides declarative, composable, and reproducible services for Nix development environment, and is based on flake-parts. Enabling users to have NixOS-like service on macOS and Linux.

nixpkgs (https://github.com/NixOS/nixpkgs) is a monorepo containing a collection of Nix packages. It also includes various utility Nix functions (like writeShellApplication), as well as the NixOS Linux distribution (including the Module System).

nix-darwin brings NixOS like configuration to macOS, allowing you to install packages (among doing other things) purely through Nix.

If you’ve ever used NixOS before, you might be familiar with the way services are managed. Let’s take a quick look at an example to understand if that will help us arrive at a solution for our problem.

In the last section, we saw how easy it is to run services in NixOS. We are looking for something similar for our development environment that runs across platforms. Additionally, the solution should:

Running services in NixOS is a breeze. For example, running a PostgreSQL Database is as simple as adding one line to your configuration:

Choose from one of the following ways to install NixOS:

[!tip] Welcome to NixOS Asia NixOS Asia is a community of Nix and NixOS users, promulgated initially from the Indian subcontinent. Talk to us on Zulip!

Whethere you are on macOS or NixOS, you can install and setup fonts in an unified fashion with Nix using home-manager.

In this second tutorial, we will walk you through the process of installing NixOS. Unlike the first installation tutorial, we will use the command line to install NixOS manually, except for using disko to specify disk partitions declaratively in Nix itself. This is the first step toward our next tutorial, where we will automate the entire installation process.

The above downloaded Nix file uses a hardcoded disk device. So, we need to replace it with the device name of the disk we want to install NixOS on. We can use lsblk to find it.

This tutorial will walk you through the steps necessary to install NixOS, enable flakes while tracking the resulting system configuration in a Git repository.
