How to diagnose Kubernetes Pod Launching problems?

I followed these instructions to create a Hello-World WebApp with C#/.NET Core 3.1 with Visual Studio 2019 V16.5.2 and deployed to Azure Kubernetes Services (AKS) and it worked great. In addition to being able to debug/single-step with Visual Studio, I could also use the kubectl run command and edit the deployment to make it a LoadBalancer and see my hello-world web page in the browser.

Then I published the same image of the WebApp to my personal DockerHub account and tried to deploy to Docker for desktop/Kubernetes. When doing kubectl get pods -o wide I saw the status of the pod is ImagePullBackOff and kubectl logs <podname> fails to give me a log where might have some hints as to the problems.

(1) How does one diagnose a problem like this with no log files?

(2) Could this be a bug since this image works on AKS? I'd prefer to use Docker Desktop.

Thanks

I am using this: kubectl describe pod {pd-id}

it shows whole bunch of the information including errors related to pulling image.

also most probably your ImagePullBackOff is related to authentication problem of kubernetes against image registry.
