Is there any way to list all PODs that are using the most CPU on the node using kubectl command. I could not see this in the official documentation.
To know which pod scheduled on a specific node has most CPU requests you can describe that node and check the Non-terminated Pods section.
kubectl describe node masternode
Non-terminated Pods: (8 in total)
Namespace Name CPU Requests CPU Limits Memory Requests Memory Limits AGE

kubectl top podname
kubectl top nodenameYou can get by using
kubectl top pods # This will give you which pod is using how much CPU and Memory
kubectl top nodes # This will give you which node is using how much CPU and MemoryMake sure metric server has deployed on the cluster.
