I want to create a VM Scale set and use a snapshot as base for my windows VMs. As the Set-AzureRmVmssStorageProfile only accepts images my first try was to convert the snapshot to an image by use:

$rgName = #...

$location = #...

$snapshotName = "mySnapshot"

$imageName = "myImage"



$snapshot = Get-AzureRmSnapshot -ResourceGroupName $rgName -SnapshotName $snapshotName



$imageConfig = New-AzureRmImageConfig -Location $location

$imageConfig = Set-AzureRmImageOsDisk -Image $imageConfig -OsState Generalized -OsType Windows -SnapshotId $snapshot.Id



New-AzureRmImage -ImageName $imageName -ResourceGroupName $rgName -Image $imageConfig

But in this case the image that is created has no Source Blob URI:

what gives me the error:

New-AzureRmVmss : The URI Microsoft.Azure.Commands.Compute.Automation.Models.PSImage does not look to be correct blob URI.

On my deploy commands for azure:

$vmss = New-AzureRmVmssConfig -Location $loc -SkuCapacity 2 -SkuName "Standard_DS1_v2" -UpgradePolicyMode "manual" -ErrorAction Stop



Add-AzureRmVmssNetworkInterfaceConfiguration -VirtualMachineScaleSet $vmss -Name "vmssNetwork" -Primary $true -IPConfiguration $ipConfig 

Set-AzureRmVmssStorageProfile -VirtualMachineScaleSet $vmss -OsDiskCreateOption "FromImage" -OsDiskCaching "None" `

            -Image $ImgRef -OsDiskOsType Windows -OsDiskName "C"

Set-AzureRmVmssOSProfile -ComputerNamePrefix $vmNamePrefix -AdminUsername $adminUsername -AdminPassword $adminPassword -VirtualMachineScaleSet $vmss



New-AzureRmVmss -ResourceGroupName $currentrg -Name $vmssName -VirtualMachineScaleSet $vmss -Verbose -ErrorAction Stop;

Is there a other way to create the image or set a source blob uri?
Or is it possible to use a snapshot for creating an VM Scale Set?

Afer the hint from Charles Xu I changhed the image creation to first create a dik, but I still get the same error. New Code is:

$rgName = #...

$location = #...

$snapshotName = "mySnapshot"

$imageName = "myImage"

$storageType = 'Standard_LRS'

$diskName = "myDisk"



$snapshot = Get-AzureRmSnapshot -ResourceGroupName $rgName -SnapshotName $snapshotName



$diskConfig = New-AzureRmDiskConfig -AccountType $storageType -Location $location -CreateOption Copy -SourceResourceId $snapshot.Id

$disk = New-AzureRmDisk -Disk $diskConfig -ResourceGroupName $rgName -DiskName $diskName



$imageConfig = New-AzureRmImageConfig -Location $location

$imageConfig = Set-AzureRmImageOsDisk -Image $imageConfig -OsState Generalized -OsType Windows -ManagedDiskId $disk.Id     



New-AzureRmImage -ImageName $imageName -ResourceGroupName $rgName -Image $imageConfig

You can create an image from an Azure VM. For example, you can create a windows image from the windows VM through PowerShell, see Create and use a custom image for virtual machine scale sets with Azure PowerShell. When the image is OK, Just create the VMSS like this:

New-AzureRmVmss `

  -ResourceGroupName "myResourceGroup" `

  -Location "EastUS" `

  -VMScaleSetName "myScaleSet" `

  -VirtualNetworkName "myVnet" `

  -SubnetName "mySubnet" `

  -PublicIpAddressName "myPublicIPAddress" `

  -LoadBalancerName "myLoadBalancer" `

  -UpgradePolicyMode "Automatic" `

  -ImageName "yourImage"

Also, the snapshot is OK, but you should create the image from the snapshot first. And then create the VMSS from the image. With the command New-AzureRmImage, the image should be a managed image, so you cannot see the URI. Just use the managed image Id in the command like this:

Set-AzureRmVmssStorageProfile -VirtualMachineScaleSet $vmss -OsDiskCreateOption "FromImage" -OsDiskCaching "None" -ImageReferenceId yourImageId -OsDiskOsType Windows -OsDiskName "C"

And just talk about how to create images, I would suggest you the Packer and there is an example here.

Update

I assume that your custom image is prepared. And the PowerShell script like this:

#Get the custom image 

$image = Get-AzureRmImage -ResourceGroupName charlesTerraform -ImageName myPackerImage



# Get the existing Vnet

$vnet = Get-AzureRmVirtualNetwork -ResourceGroupName charlesTerraform -Name pakcerVnet



#IP configuration

$ipName = "ipConfig"



#create the IP configuration

$ipConfig = New-AzureRmVmssIpConfig -Name $ipName -LoadBalancerBackendAddressPoolsId $null -SubnetId $vnet.Subnets[0].Id



#create vmss configuration

$vmss = New-AzureRmVmssConfig -Location "East US" -SkuCapacity 2 -SkuName "Standard_DS1_v2" -UpgradePolicyMode "manual" -ErrorAction Stop



##Add the network interface configuration to the scale set configuration

Add-AzureRmVmssNetworkInterfaceConfiguration -VirtualMachineScaleSet $vmss -Name "vmssNetwork" -Primary $true -IPConfiguration $ipConfig 



# set the stroage profile 

Set-AzureRmVmssStorageProfile -VirtualMachineScaleSet $vmss -OsDiskCreateOption "FromImage" -OsDiskCaching "None" -ImageReferenceId $image.Id -OsDiskOsType Linux 



#set the os profile

Set-AzureRmVmssOSProfile -ComputerNamePrefix "Test" -AdminUsername "azureuser" -AdminPassword "azureuser@2018" -VirtualMachineScaleSet $vmss



#create the vmss

New-AzureRmVmss -ResourceGroupName charlesTerraform -Name TestVmss -VirtualMachineScaleSet $vmss

folks. So what about create a "Virtual Machine in Scale Set" from a customized snapshot. Is this possible or one scale set could only have one base image and all vms under this scale set could only reimaged to the same baseline ?
