Azure Policy to Install Custom Script Extension From Private Github Repository

[pravyn]

Hello,

We are developing a custom script extension that will be deployed as a policy. To achieve this, we need to retrieve PowerShell code from a private GitHub repository. The PowerShell script is responsible for installing the required extension.

While the code snippet provided works for public repositories (sample below) , we are seeking guidance on how to securely pass the Personal Access Token (PAT) to download the PowerShell script from a private repository.

"fileUris": [
                      ],      https://github.com/Azure/azure-quickstart-templates/blob/b1908e74259da56a92800cace97350af1f1fc32b/201-list-storage-keys-windows-vm/getprocess.ps1
 
                      "commandToExecute": "powershell.exe -ExecutionPolicy Unrestricted -File getprocess.ps1"

Thanks,
Praveen
