This script creates a virtual machine by attaching an existing managed disk as OS disk. Use this script in preceding scenarios:
If you don't have an Azure subscription, create an Azure free account before you begin.
#Provide the subscription Id
$subscriptionId = 'yourSubscriptionId'
#Provide the name of your resource group
$resourceGroupName ='yourResourceGroupName'
#Provide the name of the snapshot that will be used to create OS disk
$snapshotName = 'yourSnapshotName'
#Provide the name of the OS disk that will be created using the snapshot
$osDiskName = 'yourOSDiskName'
#Provide the name of an existing virtual network where virtual machine will be created
$virtualNetworkName = 'yourVNETName'
#Provide the name of the virtual machine
$virtualMachineName = 'yourVMName'
#Provide the size of the virtual machine
#e.g. Standard_DS3
#Get all the vm sizes in a region using below script:
#e.g. Get-AzVMSize -Location westus
$virtualMachineSize = 'Standard_DS3'
#Set the context to the subscription Id where Managed Disk will be created
Select-AzSubscription -SubscriptionId $SubscriptionId
$snapshot = Get-AzSnapshot -ResourceGroupName $resourceGroupName -SnapshotName $snapshotName
$diskConfig = New-AzDiskConfig -Location $snapshot.Location -SourceResourceId $snapshot.Id -CreateOption Copy
$disk = New-AzDisk -Disk $diskConfig -ResourceGroupName $resourceGroupName -DiskName $osDiskName
#Initialize virtual machine configuration
$VirtualMachine = New-AzVMConfig -VMName $virtualMachineName -VMSize $virtualMachineSize
#Use the Managed Disk Resource Id to attach it to the virtual machine. Please change the OS type to linux if OS disk has linux OS
$VirtualMachine = Set-AzVMOSDisk -VM $VirtualMachine -ManagedDiskId $disk.Id -CreateOption Attach -Windows
#Create a public IP for the VM
$publicIp = New-AzPublicIpAddress -Name ($VirtualMachineName.ToLower()+'_ip') -ResourceGroupName $resourceGroupName -Location $snapshot.Location -AllocationMethod Dynamic
#Get the virtual network where virtual machine will be hosted
$vnet = Get-AzVirtualNetwork -Name $virtualNetworkName -ResourceGroupName $resourceGroupName
# Create NIC in the first subnet of the virtual network
$nic = New-AzNetworkInterface -Name ($VirtualMachineName.ToLower()+'_nic') -ResourceGroupName $resourceGroupName -Location $snapshot.Location -SubnetId $vnet.Subnets[0].Id -PublicIpAddressId $publicIp.Id
$VirtualMachine = Add-AzVMNetworkInterface -VM $VirtualMachine -Id $nic.Id
#Create the virtual machine with Managed Disk
New-AzVM -VM $VirtualMachine -ResourceGroupName $resourceGroupName -Location $snapshot.Location
Run the following command to remove the resource group, VM, and all related resources.
Remove-AzResourceGroup -Name myResourceGroup
This script uses the following commands to get managed disk properties, attach a managed disk to a new VM and create a VM. Each item in the table links to command specific documentation.
Command | Notes |
---|---|
Get-AzDisk | Gets disk object based on the name and the resource group of a disk. Id property of the returned disk object is used to attach the disk to a new VM |
New-AzVMConfig | Creates a VM configuration. This configuration includes information such as VM name, operating system, and administrative credentials. The configuration is used during VM creation. |
Set-AzVMOSDisk | Attaches a managed disk using the Id property of the disk as OS disk to a new virtual machine |
New-AzPublicIpAddress | Creates a public IP address. |
New-AzNetworkInterface | Creates a network interface. |
New-AzVM | Create a virtual machine. |
Remove-AzResourceGroup | Removes a resource group and all resources contained within. |
For marketplace images use Set-AzVMPlan to set the plan information.
Set-AzVMPlan -VM $VirtualMachine -Publisher $Publisher -Product $Product -Name $Bame
