Auto Assign DSC Configuration to Node based on Node Name

Question

Hi All,

I have a bunch of compiled configurations on my dev computer that I'm importing into Azure Automation using the "Import-AzAutomationDscNodeConfiguration" cmdlet.

Is there a way to auto assign the complied mof automatically to the intended node based on the node name? or do I have to go into each node and pick the corresponding configuration?

I have searched the documentation with no avail.

Digging a little more I found this cmdlet: Set-AzAutomationDscNode and was able to create the following script for that purpose:

param (  
        [String]$PathToMof,  
        [String]$AutomationAccountName   
        [String]$ResourceGroupName   
)  
  
Import-module AZ.Automation  
Connect-AzAccount  
  
# Get Node Name from Mof Path  
$NodeName   = (Get-ItemProperty -path $PathToMof).BaseName  
  
# Get Configuration Name from Mof Content  
$Line       = Get-Content $PathToMof | Select-String -SimpleMatch "ConfigurationName = " | Select-Object -First 1   
$ConfigName = [regex]::Matches($Line, "(?<=([`"']))(?:(?=(\\?))\2.)*?(?=\1)").Value  
  
$AzParams = @{  
        AutomationAccountName = $AutomationAccountName  
        ResourceGroupName     = $ResourceGroupName  
}  
  
# Import Complied Configuration to Az Automation  
$NodeConfig = Import-AzAutomationDscNodeConfiguration @AzParams -ConfigurationName $ConfigName -Path $PathToMof  
  
# Get Node Object to Extract ID  
$AzAutoNode = Get-AzAutomationDscNode @AzParams -Name $NodeName  
  
# Assign Node Configuration  
Set-AzAutomationDscNode @AzParams -Id $AzAutoNode.Id -NodeConfigurationName $NodeConfig.Name
