About the Book

Whenever you think of Desired State Configuration (DSC), you think of Windows systems and bring them to the desired state they should be when defined from a configuration. However, DSC version 3 threw a whole different ballgame and expanded more to become cross-platform after the class-based DSC resources were decoupled from Windows already, supporting Linux-based systems.

In this extensive handbook, you will learn about the philosophy and rise of ideas from the core PowerShell DSC members and community. There's also a whole different set of terminologies to explore, as the core engine has been written in Rust. The book covers this in more depth, touches upon new operations, like `Export` or `Delete`, and how you can get started building command-based DSC resources. In the last chapter, advanced concepts are teached, covering the adapter lookup table for adapted resources, migration from DSC v1/v2 Configuration Documents and how DSC v3 has implemented localization.

DSC is not a PowerShell cmdlet anymore, but instead an executable for different platforms. You can now easily run it on your MacOS, Windows, or Linux machine. This handbook will use Windows as primary system.

Is this book for you?

This book is for the system administrator, DevOps engineer, and even developers that are managing large scale cross-platform systems. Yes, you heard that right. All these roles can make use of this book even though you don't have to manage these systems. Instead, developers can assist system administrators or DevOps engineers by writing tools in different languages other then PowerShell, which in turn can hook into DSC's core engine. You will learn all about it in this book!
