New-Nano: automating Windows Nano Server lab builds with PowerShell

I wrote this function to automate Nano Server lab builds into Hyper-V. You need to supply the “Windows Server 2016 Technical Preview 5” ISO, which you can get here or here. My script is based partially on ideas presented in the Microsoft TechNet article “Getting Started with Nano Server“.

You will need to have Hyper-V on your computer, have a Hyper-V switch on a network that has DHCP running somewhere (if you have a switch in Hyper-V defined as “External”, this should work fine). You will also need to supply a working directory.

New-Nano copies the required files from the ISO, runs Microsoft’s cmdlet New-NanoServerImage to build a Hyper-V disk image, creates a new VM from that disk image, starts the VM, and gets network information from the VM. The function then runs an example PowerShell Session to demonstrate connectivity to the new Nano VM. Total build time in my tests is a little over three minutes.

If you look to the bottom of the script, you will see an example of how to call the New-Nano function.

Further refinements would be to install features and packages to the Nano, and to do domain joins. Please note that this should only be used for a lab environment because the administrator password is in plaintext. If this was going into a production environment, you would want to encode it.

Enjoy. Please try it out and leave a comment.
