Question

For one of the pod in the AKS cluster showing as pending status from long time and when I check through describe pod getting this message.

Events:

Hi,

It could be resources limit and request on the pod itself are higher than the exiting resources on the nodes, can you share the output of the describe command:
kubectl describe pod <pod-name> -n <namespace>
