Hi @Yongchao Liu (Neusoft America Inc) ,
Thanks for providing the additional information.
Could you provide what is the status you are seeing in
kubectl get pods/<affected-pod> and also provide 'Events' log for same by doing a
kubectl describe pods/<affected-pod> ?
You will see something under Events for the pod that states why the pod is not getting scheduled. For example, please see below -
Looking forward to your reply.
