Sample script to upload a VHD to Azure and create a new VM

This script takes a local .vhd file from a generalized VM and uploads it to Azure, creates a Managed Disk image and uses the to create a new VM.

This sample requires Azure PowerShell Az 1.0 or later. Run Get-Module -ListAvailable Az to see which versions are installed. If you need to install, see Install Azure PowerShell module.

Run Connect-AzAccount to sign in to Azure.

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

Clean up deployment

Run the following command to remove the resource group, VM, and all related resources.

Remove-AzResourceGroup -Name $resourceGroup

Script explanation

This script uses the following commands to create the deployment. Each item in the table links to command specific documentation.

Command Notes
