Azure PowerShell - Create VM in existing service

Question

I use a powershell script to create a virtual machine in azure.

The script goes like this :

$serviceName = 'nameOfTheService'
$vmName = 'nameOfTheVM'

$osDiskName = 'nameOfTheDisk'

$config = New-AzureVMConfig -Name $vmName -DiskName $osDiskName -InstanceSize $size | Add-AzureEndPoint -Name 'Remote Desktop' -LocalPort 3389 -PublicPort 3389 -Protocol tcp

New-AzureVM -ServiceName $serviceName -Location $location -VMs $config

First time runs just fine.

If I delete the VM and re-run the script, it says that "the specified DNS name is already take", wich is true because I did not deleted the cloud service.

Is there a way I can reuse the existing cloud service when creating the machine?

When you deploy several VMs to one CouldService, you only need to define AffinityGroup to the first VM you create, not the later ones.

#Create VM with a New Cloud Service 
New-AzureVM –ServiceName $cloudService -VMs $vmConfig -VNetName $virtualNetwork -AffinityGroup $affinityGroup
#Create VM into an existing Cloud Service
New-AzureVM –ServiceName $cloudService -VMs $vmConfig -VNetName $virtualNetwork
