Connect machines at scale by running PowerShell scripts with Configuration Manager

  • Article

Microsoft Configuration Manager facilitates comprehensive management of servers supporting the secure and scalable deployment of applications, software updates, and operating systems. Configuration Manager has an integrated ability to run PowerShell scripts.

You can use Configuration Manager to run a PowerShell script that automates at-scale onboarding to Azure Arc-enabled servers.

Before you get started, be sure to review the prerequisites and verify that your subscription and resources meet the requirements. For information about supported regions and other related considerations, see supported Azure regions. Also review our at-scale planning guide to understand the design and deployment criteria, as well as our management and monitoring recommendations.

If you don't have an Azure subscription, create a trial subscription before you begin.

Prerequisites for Configuration Manager to run PowerShell scripts

The following prerequisites must be met to use PowerShell scripts in Configuration Manager:

  • The Configuration Manager version must be 1706 or higher.
  • To import and author scripts, your Configuration Manager account must have Create permissions for SMS Scripts.
  • To approve or deny scripts, your Configuration Manager account must have Approve permissions for SMS Scripts.
  • To run scripts, your Configuration Manager account must have Run Script permissions for Collections.

Generate a service principal and prepare the installation script

Before you can run the script to connect your machines, you'll need to do the following:

  1. Follow the steps to create a service principal for onboarding at scale. Assign the Azure Connected Machine Onboarding role to your service principal, and limit the scope of the role to the target Azure landing zone. Make a note of the Service Principal Secret, as you'll need this value later.

  2. Follow the steps to generate the installation script from the Azure portal. While you will use this installation script later, do not run the script in PowerShell.

Create the script in Configuration Manager

Before you begin, check in Configuration Manager Default Settings that the PowerShell execution policy under Computer Agent is set to Bypass.

  1. In the Configuration Manager console, select Software Library.
  2. In the Software Library workspace, select Scripts.
  3. On the Home tab, in the Create group, select Create Script.
  4. On the Script page of the Create Script wizard, configure the following settings:
    1. Script Name - Onboard Azure Arc
    2. Script language - PowerShell
    3. Import - Import the installation script that you generated in the Azure portal. Screenshot of the Create Script screen in Configuration Manager.
  5. In the Script Wizard, paste the script generated from Azure portal. Edit this pasted script with the Service Principal Secret for the service principal you generated.
  6. Complete the wizard. The new script is displayed in the Script list with a status of Waiting for approval.

Approve the script in Configuration Manager

With an account that has Approve permissions for SMS Scripts, do the following:

  1. In the Configuration Manager console, select Software Library.
  2. In the Software Library workspace, select Scripts.
  3. In the Script list, choose the script you want to approve or deny. Then, on the Home tab, in the Script group, select Approve/Deny.
  4. In the Approve or deny script dialog box, select Approve for the script. Screenshot of the Approve or deny script screen in Configuration Manager.
  5. Complete the wizard, then confirm that the new script is shown as Approved in the Script list.

Run the script in Configuration Manager

Select a collection of targets for your script by doing the following:

  1. In the Configuration Manager console, select Assets and Compliance.
  2. In the Assets and Compliance workspace, select Device Collections.
  3. In the Device Collections list, select the collection of devices on which you want to run the script.
  4. Select a collection of your choice, and then select Run Script.
  5. On the Script page of the Run Script wizard, choose the script you authored and approved.
  6. Click Next, and then complete the wizard.

Verify successful connection to Azure Arc

The script status monitoring will indicate whether the script has successfully installed the Connected Machine Agent to the collection of devices. Successfully onboarded Azure Arc-enabled servers will also be visible in the Azure portal.
