Access Azure VM with PowerShell and MS Live credentials - powershell

Question

I want to change the size an Azure VM with powershell. The reason is: I use machine for development. I need A2 size for 4 hours a day. The owner of the VM asked to switch the size of the machine to A0 when I do not develop. I have access to the Azure subscription with my MS Live account. Now I change the size manually through Azure Portal. I want to automate this task with PowerShell. The script should set the size to A2, wait for 4 hours and set it back to A0. I just want to doubleclick the script before starting my development and just forget about the question.
I have the following understanding of the general procedure:
Run Import-AzurePublishSettings
Run Select-AzureSubscription
Get VM object with Get-AzureVM
Run Set-AzureVMSize
Update-AzureVM
I can not get publish profile, because I do not own the machine. Is there a way to authenticate with MS Live account?

Answer 1

Skip the Import-Azurepublish and do a Add-AzureAccount instead. That will popup UI for authenticating with your MS Live account.
Once that is done you can use Select-AzureSubscription
For Classic Deployment you need this:
# authenticate if no account is already added to the powershell session
if (!(Get-AzureAccount)){ Add-AzureAccount }
# Get the vm object out of azure
$vm = get-azurevm | where name -eq "name of the vm"
# Now all you need is to is update the VM with its new size:
$vm | Set-AzureVMSize -InstanceSize Medium | Update-AzureVM
If the VM is deployed via the Resource Manager (RM Model)
if (!(Get-AzureRMContext)){ Add-AzureRmAccount }
Select-AzureRmSubscription -SubscriptionId "{subscriptionId}"
$vm = Get-AzureRmVm | where name -eq "{vmName}"
$vm.HardwareProfile.vmSize = "Medium"
Update-AzureRmVM -VM $vm
btw. Medium is what A2 is called in the API.
