kubectl top pod - Display Resource (CPU/Memory/Storage) usage of pods
kubectl top pod [OPTIONS]
Display Resource (CPU/Memory/Storage) usage of pods.
The 'top pod' command allows you to see the resource consumption of pods.
Due to the metrics pipeline delay, they may be unavailable for a few minutes since pod creation.

--containers=false If present, print usage of containers within a pod.
--no-headers=false If present, print output without headers.
-l, --selector="" Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)
--sort-by="" If non-empty, sort pods list using specified field. The field can be either 'cpu' or 'memory'.
