Very powerful also in a hybrid environment with the hybrid worker.
You can run, manage, schedule the same scripts but also for on-prem VMs.

I too am getting the error:

Invoke-AzVMRunCommand : A parameter cannot be found that matches parameter name ‘ScriptString’.

I am running the command in a Powershell (v7.1) runbook through my Azure Automation account.

In reply to David. you can save your Powershell script in a Blob and then before you run the Invoke-AzVMRunCommand, download the .ps1 file to the runbook temp folder

In reply to David. Yes, but you would need to build a script to download the file on to the machine and then run it.

one question can run the code in the block or just run a .ps1 that on a blob ?

In reply to Ryan.

Hi Ryan,

please try to send the invoke-azvmruncommand to a variable. You can then read the (output) message from this variable….

$result = Invoke-AzVMRunCommand ….

If ($result.Value.Count -gt 0) { Write-Output $result.Value[0].Message }

Have fun….

Thanks for the detailed write-up. Question: is there a way to return the output of the script executed against each VM in the Azure portal? For example, I’d like to run the ‘uptime’ command across my fleet and have those results appear in the output for the playbook. Thanks in advance.
