Learning PowerShell DSC - Second Edition

By: James Pogran

Overview of this book

The main goal of this book is to teach you to configure, deploy, and manage your system using the new features of PowerShell v5/v6 DSC. This book begins with the basics of PowerShell Desired State Configuration, covering its architecture and components. It familiarizes you with the set of Windows PowerShell language extensions and new Windows PowerShell commands that make up DSC. Then it helps you create DSC custom resources and work with DSC configurations with the help of practical examples. Finally, it describes how to deploy configuration data using PowerShell DSC. Throughout this book, we will be focusing on concepts such as building configurations with parameters, the local configuration manager, and testing and restoring configurations using PowerShell DSC. By the end of the book, you will be able to deploy a real-world application end-to-end and will be familiar enough with the powerful Desired State Configuration platform to achieve continuous delivery and efficiently and easily manage and deploy data for systems.

Locally pushing DSC configurations

What do we mean by "pushing DSC configurations locally?" When we apply a DSC configuration to the computer we are logged into, we are applying or pushing the DSC configuration onto the computer. We call it pushing because we are actively copying the MOF file and triggering an execution on the target node; we are active participants in the whole process. The Start-DSCConfiguration cmdlet does the work for us, but we are actively requesting the operations to be performed. This is clear when we contrast this with a DSC pull server. The DSC engine on the target node pulls the DSC configuration when an execution run is scheduled, whereas we push the DSC configuration to the target node when we want to execute it interactively using Start-DSCConfiguration.

The Start-DSCConfiguration cmdlet syntax we will be using is this:
