Can you share repro instructions that triggered the images to restart?

Hi @fady-azmy-msft , this is the image i am trying to pull.
docker pull mcr.microsoft.com/windows/servercore:ltsc2022

Can you also share the steps you took that triggered this bug?

I'm afraid I'll need a bit more details on your repro steps just to make sure we repro the same setup. See this issue as an example of repro steps.

Hello, @fady-azmy-msft i have been using the different windows images mcr.microsoft.com/windows/servercore:ltsc2022 this is one of the image of them . But when i used this image in the kubernetes pod the pod is restarting multiple times. same with all windows images what might be the issue.
can you please clarify.

Hi, I'm trying to understand your situation a bit more. Correct me if I'm wrong but I'm assuming that you're:

  • using a Jenkins server to build, test, and deploy Windows Containers (specifically Windows Server Core 2022)
  • connecting that Jenkins server AKS
  • AKS is managing your pod of Windows Containers

If you're not using AKS to manage your pod and connect Jenkins as a CI/CD server, we may ask you to first trying deploying the pod with AKS then connecting Jenkins. If you are using AKS, did you first check to see that normally deploying a pod worked before connecting the CI/CD component?

Hello @ntrappe-msft for me the pod is creating with linux images. But only the issue is i am unable to run windows images it is saying unable to pull the image.
can you please clarify that can we run more than two windows images in a single pod

Thanks for explaining your problem a bit further. What I'm hearing is that you:

  • Have a Kubernetes cluster with a Linux node as the host
  • Will be running both Linux and Windows Containers in this cluster
  • When you try to pull a Windows container image, you're getting an error message

If all the above is true, then there is a problem. All containers in a pod or cluster must share the same host operating system. However, Windows containers require a Windows host and Linux containers require a Linux host to run. It's not possible to run Windows container images directly on a Linux node.

When we see errors with failing to pull an image like docker pull mcr.microsoft.com/windows/servercore:ltsc2022, it's often because Docker Desktop is switched to "Linux containers" or another platform mismatch. In this case, it's stemming from an incompatible node type.

Next Steps

You can create a Kubernetes cluster with both Windows and Linux nodes but you'll have to schedule your Windows containers to run on Windows nodes. Here are 2 resources to help you with this:
