[packer] Packer hangs during PowerShell inline script execution (Windows 10 image)

Emin Askerov Mon, 10 Jun 2019 04:31:33 -0700

Hello All,


I am stuck with simple Packer template which provisions Windows 10 image in 
Azure. Template includes inline PowerShell script which is executed with 
elevated privileges and installs Azure PowerShell modules and then 
generalizes image using sysprep. The issue is that Packer simply hangs 
during running the inline script.  I’ve tried to debug this script on the 
separate VM and it works as expected, but when it is executed within Packer 
template it hangs for some reason. Template and debug logs are provided 
below:


Any ideas what am I doing wrong or this is a bug?
