How might you scope this to the subscription level. I’m struggling with doing so. I found one of the folks that commented but it seems like his script loops through each subscription and then through each resource and then the next subscription and so on….

Any help would be greatly appreciated.

In reply to Thomas Maurer. Thank you that was the problem I was using powershell v5. Thomas, if I wanted to use this script to copy a .exe from repository to the server, can it be done?

Hi Thomas,

I have multiple subscription and at one go I need to start it parallelly but it is not working for me. below is my code
$subs | ForEach-Object -parallel {
Select-AzSubscription -Subscription “$($_.name)” -ErrorAction Stop -ErrorVariable errorvar
$vmdetails+=Get-AzVM -Status | Where-Object {$_.StorageProfile.OsDisk.OsType -eq ‘Windows’ -and $_.PowerState -eq ‘VM running’}
$vmdetails
}
$vmdetails | ForEach-Object -Parallel {

$Extensions = Get-AzVMExtension -VMName $_.Name -ResourceGroupName $_.ResourceGroupName
if($Extensions.ProvisioningState -notcontains ‘Failed’)
{
$out2=Invoke-AzVMRunCommand -ResourceGroupName $_.ResourceGroupName -Name $_.Name -CommandId ‘RunPowerShellScript’ -ScriptPath .\RunScript.ps1
}
}
$ subs contains all my subscription details

If I remove parallel for subs then code works like a charm

Hello
I got a case for run a PowerShell script to install some software on VM. I plan to use Runbook with managed identity. In that runbook I will gather all VMs from the RG, and than run the script which would be downloaded to the VM from Blob. All those actions needs to be done from runbook. I do not want to use Set-AzureVMCustomScriptExtension for that as it needs to be scheduled action per RG. Can I use Invoke-AzVMRunCommand with the localpath as a value for -script paramter ?

Hi Thomas,

For longer scripts that I want to run often, is it possible to add a custom default script to the eleven that Microsoft provides, or do I have to use ‘RunPowerShell Script’ every time and paste in my code?

Thanks
