In the case where we have configured the LCM in ApplyAndAutocorrect mode, upon detecting that the Current State and Desired State do not match, it will make a call back into the Set function and attempt to bring the environment back in its Desired State. And the Test method obtains information about the Current State by making a call into the Get function and compares it against the Desired State. The Set method is responsible for bringing the environment into its Desired State. The Get method is the one responsible for obtaining information about the Current State of a given resource. What we are missing is information about the Current State.Įvery DSC resource needs to define three core functions: Get, Set and Test. It has that information on disk in the Current.mof file. By default, the LCM knows about the Desired State. Unfortunately for me, DSC is not going to help me with the example above.įor the Local Configuration Manager (LCM) to check if the environment is configured as defined or not, we need a way to obtain information about both the Current State and the Desired State of each resource defined within the DSC configuration. The goal of DSC is to make sure the Current State of an environment matches its Desired State.
I am just short of 5’9″, and just shy of 180 pounds. However, as much as it saddens me to admit it, the result of Test-DSCConfiguration -Detailed on this “Desired State” would be False for both resources. If you were to ask my wife what my desired state should be, it would be something like: Let’s look at an example to illustrate this concept.
We currently have the following official ReverseDSC Orchestrator Scripts available on GitHub: These technology-specific scripts are referred to as Orchestrator Scripts, and include logic that is specific to the current piece of technology being extracted. While ReverseDSC core is technology agnostic, and it provides interfaces to extract current configurations into DSC scripts, it does require a technology-specific component to be able to properly extract information from the existing environment. As long as there is a DSC Module for the technology component, you can use ReverseDSC to extract its current configuration. ReverseDSC, at its core, is an extensible solution that you can use to extract your existing environment as a Desired State Configuration (DSC) script.

That’s right, you can simply run a script against your existing complex environment, such as SharePoint, and automatically generate these 150,000 lines of DSC code that represent your environment. ReverseDSC is a module that provides a set of functions that can be used to reverse engineer an existing environment into a DSC script. Most organizations already have an existing investment in technology solutions, and rewriting their imperative set of scripts into a declarative DSC configuration script is not a project everyone is willing to undertake. So how can an organization that has an existing SharePoint footprint get started with DSC, without spending months re-writing their configuration? It can simply use ReverseDSC. Some of the most complex SharePoint environments I have seen being deployed with PowerShell DSC exceed the 150,000 lines of code. While the SharePointDSC module is very mature, having been around for almost 3 years, it still represents a fair investment for clients to re-write their Imperative deployment script into DSC. One of the most complex solutions out there to manage via DSC is certainly SharePoint. This enables organizations to create a complex automation solution that allows them to manage, via DSC, different components of their technology stacks. There are now several hundred DSC modules available in the PowerShell Gallery. PowerShell Desired State Configuration (DSC) has been around for a few years now, and many organizations are using it to help them automate parts of their DevOPS pipeline.
