Cloud and Datacenter Management by Anders Bengtsson

Deploy new VM and attach a template data disk

I was working on a scenario were we needed to deploy new VMs and attach a data disk that included a number of tools. This Azure Powershell script will deploy a new VM, make a copy of a template data disk with all the tools, and attach the disk to the new VM.

Before you run the script you need to update at least network settings, source storage Account and target storage account. You might also update VMsize, CloudService and VMName. The current script will create a new VM with a named based on the current date and time. Information about Your storage accounts can be found in the Azure management portal, under each storage Account.

## Parameters

### Admin account settings
$login = “AdminUser”
$Password = “YourSecretPassword!!”

### Vm name and cloud service settings
$TimeStamp = Get-Date -Format ddHHmmss
$NewVMName = “TEST-” + $TimeStamp
$CloudServiceName = Get-AzureService -ServiceName myCloudService
$InstanceSize = “Small”

### Network Settings
$SubnetName = “Subnet-1”
$VNetName = “vnet01”

### Source Storage Account and tool disk source URL
$srcStorageAccount = “contosostorage201501”
$srcStorageKey = “FJHmK//VbvHeeEgRqukL1015XjP2mU+DQvy65TmCR9TMw==”
$srcUri = “https://contoso0001.blob.core.windows.net/vhds/myToolsDisk.vhd”

### Target Storage Account and blob container settings
$destStorageAccount = “contoso0002”
$destStorageKey = “f94MIsNiwrv4qJBqEOfbVUQeSNkvT4QA==”
$containerName = “vhds”
