Windows Nano Server Images for 7.4+

[Herr-Sepp]

Summary of the new feature / enhancement

Since 9f48a7b the Windows nano server images are rated as unstable.

What is the reason for this?
Is it possible that we will get nano-images with a current powershell again in the future or is that no longer possible?

Is it still safe to use the 7.2 nanoimage?

Proposed technical implementation details (optional)

So https://mcr.microsoft.com/en-us/product/powershell/tags says that the tags

• nanoserver
• nanoserver-1809
• nanoserver-ltsc2022
• 7.2-nanoserver-ltsc2022
• 7.2-nanoserver-1809
• 7.3-nanoserver-ltsc2022
• 7.3-nanoserver-1809
• preview-nanoserver-ltsc2022
• preview-nanoserver-1809

are not longer supported and not longer build.

But

• lts-7.2-nanoserver-ltsc2022
• lts-7.2-nanoserver-1809
• lts-nanoserver-ltsc2022
• lts-nanoserver-1809

are supported and build regulary.

But please note:
lts-7.2-nanoserver-ltsc2022 and lts-nanoserver-ltsc2022 are the same Image (Powershell 7.2) even if "lts" should be 7.4.
Same for lts-7.2-nanoserver-1809 and lts-nanoserver-1809.

Even lts-windowsservercore-ltsc2022 is Powershell 7.2 although there is a 7.4 image for servercore

So "lts"-tags are wrong and Powershell 7.4+ is missing for Nanoserver

What is the difference between mcr.microsoft.com/powershell:7.4-windowsservercore-ltsc2022 and mcr.microsoft.com/powershell:7.4-windowsserver-ltsc2022?

It seems that there is a lack of support for windows images 😔

• No nano images anymore
• No 2025 image at all

Would it be difficult to consider supporting all 3 flavors of windows images (nanoserver, servercore and server) for windows 2019, 2022 and 2025 ?

All upstream images are available (except server:ltsc2019) 👍🏻

Upstream images references:

server
servercore
nanoserver
