Issue to track 20H2 support

[anamnavi]

This issue will track when full windows 20H2 support will be back and we can publish those images to ACR. At the moment, we have provided images and corresponding dockerfiles for nanoservercore and windowsservercore 20H2 distributions but can't publish it to ACR.

An issue has been created on the ACR repo too: Azure/acr#532

@anamnavi @TravisEz13 Any news on this? I see that LTSC 2022 has been released, so I guess it's supported in ARC. It'd be nice to support the last SAC as well.

[TravisEz13]

We have images available for ltsc2022. You'll have to ask ACR about their plan to release support for ltsc2022. We have moved to an internal preview environment to get support early.

[TravisEz13]

@anamnavi plans to add 20H2 images soon.

I find it quite unfortunate that there's no news on this subject. It feels like ACR is lagging behind and will become end-of-life.

@GrumpyMeow We can support 2022, feel free to submit a PR.

Update (2021-10-03):
looking at your ask again, you are trying to run thing on 20H1, you can't run newer versions on an older host on Windows.

[vboulineau]

@TravisEz13 ltsc2022 is already published on DockerHub, but still nothing for 20H2. It's not great because 20H2 starts to be used as current SAC by multiple providers, like GKE: https://cloud.google.com/kubernetes-engine/docs/how-to/creating-a-cluster-windows#1.20

@vboulineau, Great, feel free to submit a PR. We are still working on getting 2022 support fully out. We'll work back from there as time allows.

cc @anamnavi, I don't know if you have time to add 20H2 images.

[vboulineau]

I think the misunderstanding came from ACR support: it does now support up to Windows 2022 (with all versions in between), not only 2022. I've opened the PR to remove the BrokenFlag for 20H2 and hopefully it should build successfully.

[vboulineau]

Thanks for merging the PR quickly. Is the image publication to mcr.microsoft.com automated? Because I don't see the tags there yet: https://mcr.microsoft.com/v2/powershell/tags/list

I wonder if I did not miss to update release/servicing/windowsservercore/getLatestTag.ps1

[TravisEz13]

getlatesttag.ps1 shouldn't be used anymore. I think it should all be released now. We aren't allowed to automatically trigger off PR merges. We usually release a few days after the second Tuesday of the month.
