Top of pods in a node

kubectl get pods --all-namespaces -o wide | grep NODE_NAME | awk '{print $1" "$2}' | xargs -n2 kubectl top pods --no-headers --namespace | sort -t ' ' --key 2 --numeric --reverse

List pods resources requests

kubectl get pod -A -o custom-columns="Name:metadata.name,CPU-request:spec.containers[*].resources.requests.cpu,CPU-limit:spec.containers[*].resources.limits.cpu,Memory-request:spec.containers[*].resources.requests.memory,Memory-limits:spec.containers[*].resources.limits.memory"

List per node resources requests and limits
