Читать книгу Windows Server 2022 & Powershell All-in-One For Dummies - Sara Perrott - Страница 20

Nano provides an even simpler interface and a much more limited console, which is referred to as the Recovery Console. It isn’t available through the regular installer on the disc; instead, you have to download the container image from Microsoft. Nano has a much smaller footprint, both in terms of disk and compute needs, than Desktop Experience or Server Core. Because it has a smaller overall footprint, the attack surface is also reduced. Windows Server Nano 2022 is available only as a container base operating system image and can only be run as a container on a container host.

Nano can’t be managed through Group Policy. You need to use PowerShell DSC instead if you want to manage Nano at scale. You may be asking why you would even use Nano when it’s such a limited version of the operating system. If you need to run container workloads that use .NET, Nano is an excellent candidate because it has been optimized to run .NET Core applications.

If you want to check it out, you can download the Nano server images from Microsoft’s container registry on DockerHub with this command:

docker pull mcr.microsoft.com/windows/nanoserver

You can also go to https://hub.docker.com/_/microsoft-windows-nanoserver to see more information about the current Nano server container image. This includes a description of the image, reviews, and additional resources.

If you want to find out more about containers and using Docker commands, check out Book 8.

Note: You won’t really see Nano discussed in depth anywhere in this book because you’re far more likely to encounter the Desktop Experience or Server Core installations of Windows Server 2022.
