You can use this command to view how many pods are on each node in Kubernetes using just kubect.
kubectl get pods -A -o=custom-columns=NODE:.spec.nodeName | sort | uniq -c | sort -n
In our case, we have a limit of 25 pods per node, so we have daemon sets fail to roll out if nodes already have 25 pods. So, this is helpful.
It can also be helpful when decoming nodes as you track the removal of pods from them.
