In the announcement of wave 9 of the resource kit for PowerShell Desired State Configuration, the PowerShell team states that improvements will be published to the individual resources instead of waiting for the next wave. This got me thinking whether I really wanted to check the growing number of DSC resource individually. That’s why I created a download script to fetch all of them from TechNet.

You are probably using a regular PowerShell script to compile your node configurations into MOF files. If you are using configuration data instead of parameters, you need to pull it into your script to pass it on to the node configuration. There are two very different approaches to this.

The Meta Configuration in PowerShell Desired State Configuration (DSC) contains the parameters for the Local Configuration Manager (LCM). Before a meta configuration can be injected into a virtual machine a small section must be removed from the MOF file. This post contains two functions automate this process

In large deployments using PowerShell Desired State Configuration (DSC) it is inevitable to implement a pull server because of the centralized configuration management. The nodes connecting to a pull server are identified by a globally unique identifier (GUID). Those GUIDs are - for a start - entirely independent from the hostname. I will present several approaches to managing the GUIDs used for DSC nodes.

If you are planning to use PowerShell Desired State Configuration on a larger scale you need to take a step back and think about the design of your node configurations. In this post I will give you some hints how to approach this.

If you are using push mode for PowerShell Desired State Configuration you will be dearly missing that modules can be dynamically loaded when they are needed. The following example demonstrates how to deploy all resources from the current wave. It only uses resources contained in PowerShell 4.0.

In a previous post I described how to inject the meta as well as the node configuration. As it is, the Local Configuration Manager (LCM) does not create the scheduled tasks necessary to apply, monitor and correct the configuration. In this post I will explain how to make sure that LCM kicks off.

Many resources for Desired State Configuration require credentials to successfully execute the specified task. For example, if you are copying files or directories using the file resource, the Local Configuration Manager needs appropriate credentials to access the source location. This is a crucial requirements when the configuration is applied on a workgroup host and the source location is inaccessible by the system account. In this post, I will explain how to use credentials in the configuration.

When learning about DSC you will likely read dozens of articles and try to make sense of them. I will give you a head start and point you to the most helpful articles that I have used in the past.

In large environments, you will need to automate the meta configuration necessary to kick off the local configuration manager. Microsoft has published a lengthy article about injecting a meta as well as a node configuration into VMs and VHDs. I will present a such easier method fully integrated and supported by the LCM. This article only describes which location can be used to inject MOFs.
