I'm trying to set up a Kubernetes pod using a Windows container image from my private Docker container registry, but I'm hitting a snag. I managed to push the Windows image successfully, but when I create the pod, it shows up with the status 'ImagePullBackOff'. The error details indicate that it failed to extract a layer from the image due to missing files. I have Docker Desktop installed on Windows 10, and here's the process I've followed for the setup. Can anyone help me figure out why this is happening?

It sounds like you're trying to run Windows containers on a Linux-based Kubernetes setup, which can be tricky. Generally, you can’t pull Windows container images on a Linux kernel. Kubernetes on Docker Desktop may not support this mix properly, so you might need to ensure you're set up in a purely Windows container mode to avoid these kernel compatibility issues.
You might want to check your Docker Desktop settings to ensure Windows worker nodes are enabled. Sometimes Docker Desktop can toggle between Windows and Linux containers, but that doesn’t always translate well to Kubernetes pods. Configuring your node to prioritize Windows containers could help resolve the pull issue you're facing.
Is that configurable in Docker Desktop on Windows? Would love some guidance on how to do that.
Gotcha! So I should switch everything to Windows containers before applying? Thanks for clarifying!
