Target Audience

You are already convinced of Nix but find the learning curve extremely steep. The documentation explains a lot, but doesn't provide you the right abstractions in the right order. You are going to use Nix in a real-life project and want to do it right.

First 3 days: Discover the power of Nix and its most important foundational concepts in just 3 days! We'll guide you through the essentials, so you'll be ready to conquer complex concepts with ease. You'll learn how to streamline your workflow and get up and running in no time!

After the first 3 days: Upgrade your NixOS skills with our 2-day class! Discover how to deploy packages as services and create declarative admin interfaces - all while ensuring seamless integration with NixOS through automated testing. Perfect for Nix users looking to take their skills to the next level!

Class Goals

We teach from first principles instead of offering simple internet tutorials. Our aim is to enable you to solve future problems yourself.

In this class, you will learn how to:

Nix Part:

• Define declarative development environments
• Create reproducible, cacheable packages
• Manage, patch, pin dependencies
• Cross-compile projects (or at least prepare your project for that)
• Extend nixpkgs with complex overlays
• Create your own corporate package set
• Use Nix with and without Flakes

NixOS Part:

• Maintain NixOS setups on servers, cloud, laptops
• Define containers, VMs, custom installers
• Update and evolve systems without risk
• Create your own configurable NixOS modules
• Define powerful declarative integration tests
• Create your own corporate Linux distro

Class Content (Nix part, 3 days)

The class provides a mix of theory and practice sessions. In the theory sessions, the teacher motivates the upcoming knowledge session with real-life examples. The practice sessions are exercises which each participant can download and solve on their machine alone or in a team, receiving help from the teacher anytime.
