I’ve been working on automation for Azure VM deployment with the Microsoft CustomScriptExtension for VMs.

http azure.microsoft.com/blog/2014/04/24/automating-vm-customization-tasks-using-custom-script-extension/

The CustomScriptExtension works great from the Azure portal. I just click on the checkbox to enable it, and specify the powershell script located on the Azure storage container and it will run on the VM after it boots up. It succeeds with exit code of 0.

What I need help on is calling the CustomScriptExtension from command line via the Azure Powershell. I’m using azure-xplat-cli to create an Azure Windows VM from the CLI, and everything works (from VM launch encompassing cloud service creation and role creation, to endpoint creation, endpoint ACL creation, enabling CustomScriptExtension on the VM). When I then try to use Azure Powershell to run CustomScriptExtension it fails.

I followed the directions here: http://fabriccontroller.net/blog/posts/customizing-your-microsoft-azure-virtual-machines-with-the-new-customscript-extension/

It appears CustomScriptExtension works, the script is downloaded, but it fails with exit code 1. However, if I run the same script manually on the command line, it succeeds.

I can’t seem to get to the root cause without more verbose error messages.

Thanks in advance, Jeff

Below are some logs comparing a successful run vs the unsuccessful run via Azure Powershell:

For w99app11 when it was launched from Azure portal page (and CustomScriptExtension works). Logs follow:
