To be clear I don't know exactly how the k8s scheduler weighs CPU requests vs. limits in fitting pods to nodes. It's something I've wanted to dig further into. I do know basically how the two underlying control systems function. The cpushares system (K8S CPU requests) cannot prevent a process from taking more shares. The CPU bandwidth control system (K8S CPU limits) will throttle a process at the upper limit, but processes will not be evicted by the kubelet for hitting this limit. So if you have a pod with requests set to 20m and limits set to 200m, those pods are able to take 200m. If the scheduler is using limits to fit pods then maybe you can get 3-4 of these on a 1 core node and leave enough CPU for the other system components. If it's using some weighted combination of limits and requests then it might place more than 3-4 pods on that node, each of which is then permitted to take up to 200m. Just a theory, and I am sure there are some folks here who know exactly how it works. Maybe we'll hear from someone.
