Create File using DSC PowerShell Script - Part I

PowerShell DSC is one of my favorite topics to teach, because the technology is simply amazing. Usually I do not have enough time with a customer to teach all of the built-in resources. I would guess that the Script resource is one of the least understood.This sample has tested on PSVersion 4.0.

Applies To: Windows PowerShell 4.0, Windows PowerShell 5.0

Step 1. Script Resource Log File Example

Here is an elegantly simple use of the Script resource. We could make it more complex in many ways, but I prefer to start out with a simple use case first. The code is its own documentation. Study it carefully.

configuration WinLogAutoGen{
    param()
    #import the module of DSC for using DSCResources.
    Import-DscResource -ModuleName PSDesiredStateConfiguration;
    # use the file resource to create file.
    File windowsupdatelog{
        DestinationPath  = 'C:\Windows\windowsupdate2.log';
        Ensure = 'Present';
        Contents = 'Dev';
    }
 }
#Set mof file path in other word where to generate mof file.
WinLogAutoGen -Outputpath D:\Harshal;
#Run mof file in other word apply mof configuration to server.
Start-DscConfiguration -Wait -Verbose -Force -path D:\Harshal;

Notice the Write-Verbose statements. These are important for logging and output when the resource runs.
