Create a managed disk from a snapshot with CLI (Linux)
This script creates a managed disk from a snapshot. Use it to restore a virtual machine from snapshots of OS and data disks. Create OS and data managed disks from respective snapshots and then create a new virtual machine by attaching managed disks. You can also restore data disks of an existing VM by attaching data disks created from snapshots.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.
When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
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'
Run the script
#Provide the subscription Id of the subscription where you want to create Managed Disks subscriptionId="<subscriptionId>" #Provide the name of your resource group resourceGroupName=myResourceGroupName #Provide the name of the snapshot that will be used to create Managed Disks snapshotName=mySnapshotName #Provide the name of the new Managed Disks that will be create diskName=myDiskName #Provide the size of the disks in GB. It should be greater than the VHD file size. diskSize=128 #Provide the storage type for Managed Disk. Premium_LRS or Standard_LRS. storageType=Premium_LRS #Set the context to the subscription Id where Managed Disk will be created az account set --subscription $subscriptionId #Get the snapshot Id snapshotId=$(az snapshot show --name $snapshotName --resource-group $resourceGroupName --query [id] -o tsv) #Create a new Managed Disks using the snapshot Id #Note that managed disk will be created in the same location as the snapshot az disk create --resource-group $resourceGroupName --name $diskName --sku $storageType --size-gb $diskSize --source $snapshotId
Clean up resources
Run the following command to remove the resource group, VM, and all related resources.
az group delete --name myResourceGroupName
This script uses following commands to create a managed disk from a snapshot. Each command in the table links to command specific documentation.
|az snapshot show||Gets all the properties of a snapshot using the name and resource group properties of the snapshot. Id property is used to create managed disk.|
|az disk create||Creates a managed disk using snapshot Id of a managed snapshot|
