It requires a RunAs account and the usage of the Turn On VMs script as a pre-deployment script.

It requires a RunAs account. This script will ensure all Azure VMs in the Update Deployment are running so they recieve updates. This script will store the names of machines that were started in an Automation variable so only those machines are turned back off when the deployment is finished (UpdateManagement-TurnOffVMs.ps1) .PARAMETER SoftwareUpdateConfigurationRunContext This is a system variable which is automatically passed in by Update Management during a deployment. #> param( [string]$SoftwareUpdateConfigurationRunContext ) #region BoilerplateAuthentication #This requires a RunAs account $ServicePrincipalConnection = Get-AutomationConnection -Name 'AzureRunAsConnection' Add-AzureRmAccount ` -ServicePrincipal ` -TenantId $ServicePrincipalConnection.TenantId ` -ApplicationId $ServicePrincipalConnection.ApplicationId ` -CertificateThumbprint $ServicePrincipalConnection.CertificateThumbprint $AzureContext = Select-AzureRmSubscription -SubscriptionId $ServicePrincipalConnection.SubscriptionID #endregion BoilerplateAuthentication #If you wish to use the run context, it must be converted from JSON $context = ConvertFrom-Json $SoftwareUpdateConfigurationRunContext $vmIds = $context.SoftwareUpdateConfigurationSettings.AzureVirtualMachines $runId = "PrescriptContext" + $context.SoftwareUpdateConfigurationRunId if (!$vmIds) { #Workaround: Had to change JSON formatting $Settings = ConvertFrom-Json $context.SoftwareUpdateConfigurationSettings #Write-Output "List of settings: $Settings" $VmIds = $Settings.AzureVirtualMachines #Write-Output "Azure VMs: $VmIds" if (!$vmIds) { Write-Output "No Azure VMs found" return } } #https://github.com/azureautomation/runbooks/blob/master/Utility/ARM/Find-WhoAmI # In order to prevent asking for an Automation Account name and the resource group of that AA, # search through all the automation accounts in the subscription # to find the one with a job which matches our job ID $AutomationResource = Get-AzureRmResource -ResourceType Microsoft.Automation/AutomationAccounts foreach ($Automation in $AutomationResource) { $Job = Get-AzureRmAutomationJob -ResourceGroupName $Automation.ResourceGroupName -AutomationAccountName $Automation.Name -Id $PSPrivateMetadata.JobId.Guid -ErrorAction SilentlyContinue if (!([string]::IsNullOrEmpty($Job))) { $ResourceGroup = $Job.ResourceGroupName $AutomationAccount = $Job.AutomationAccountName break; } } #This is used to store the state of VMs New-AzureRmAutomationVariable -ResourceGroupName $ResourceGroup -AutomationAccountName $AutomationAccount -Name $runId -Value "" -Encrypted $false $updatedMachines = @() $startableStates = "stopped" , "stopping", "deallocated", "deallocating" $jobIDs= New-Object System.Collections.Generic.List[System.Object] #Parse the list of VMs and start those which are stopped #Azure VMs are expressed by: # subscription/$subscriptionID/resourcegroups/$resourceGroup/providers/microsoft.compute/virtualmachines/$name $vmIds | ForEach-Object { $vmId = $_ $split = $vmId -split "/"; $subscriptionId = $split[2]; $rg = $split[4]; $name = $split[8]; Write-Output ("Subscription Id: " + $subscriptionId) $mute = Select-AzureRmSubscription -Subscription $subscriptionId $vm = Get-AzureRmVM -ResourceGroupName $rg -Name $name -Status #Query the state of the VM to see if it's already running or if it's already started $state = ($vm.Statuses[1].DisplayStatus -split " ")[1] if($state -in $startableStates) { Write-Output "Starting '$($name)' ..." #Store the VM we started so we remember to shut it down later $updatedMachines += $vmId $newJob = Start-ThreadJob -ScriptBlock { param($resource, $vmname) Start-AzureRmVM -ResourceGroupName $resource -Name $vmname} -ArgumentList $rg,$name $jobIDs.Add($newJob.Id) }else { Write-Output ($name + ": no action taken.
