With the latest update for Azure Arc for Servers, you are now able to deploy and use extensions with your Azure Arc enabled servers. With the Custom Script extension, you can run scripts on Azure Arc enabled servers and works similar to the custom script extension for Azure virtual machines (VMs).

When this Extension is added to an Azure Arc machine, it can download PowerShell and shell scripts and files from Azure storage
