Create a managed disk from a VHD file in a storage account in the same subscription with CLI (Linux)

This script creates a managed disk from a VHD file in a storage account in the same subscription. Use this script to import a specialized (not generalized/sysprepped) VHD to managed OS disk to create a virtual machine. Or, use it to import a data VHD to managed data disk.

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

Prerequisites

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively

Run the script

#Provide the subscription Id
subscriptionId="<subscriptionId>"

#Provide the name of your resource group.
#Ensure that resource group is already created 
resourceGroupName=myResourceGroupName

#Provide the name of the Managed Disk
diskName=myDiskName

#Provide the size of the disks in GB. It should be greater than the VHD file size.
diskSize=128


#Provide the URI of the VHD file that will be used to create Managed Disk. 
# VHD file can be deleted as soon as Managed Disk is created.
# e.g. https://contosostorageaccount1.blob.core.windows.net/vhds/contosovhd123.vhd 
vhdUri=https://contosostorageaccount1.blob.core.windows.net/vhds/contosoumd78620170425131836.vhd

#Provide the storage type for the Managed Disk. Premium_LRS or Standard_LRS.
storageType=Premium_LRS


#Provide the Azure location (e.g. westus) where Managed Disk will be located. 
#The location should be same as the location of the storage account where VHD file is stored.
#Get all the Azure location supported for your subscription using command below:
#az account list-locations
location=westus

#Set the context to the subscription Id where Managed Disk will be created
az account set --subscription $subscriptionId

#Create the Managed disk from the VHD file 
az disk create --resource-group $resourceGroupName --name $diskName --sku $storageType --location $location --size-gb $diskSize --source $vhdUri

Clean up resources

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

az group delete --name myResourceGroupName
