1 is correct, 2 is partially correct, and 3 is not correct. It is absolutely true Kubernetes will reserve the amount of CPU you request, although it will also allow you to exceed that request if you attempt to and there is free CPU time to service you. 2 is correct in so far as Google run daemonsets on GKE which themselves have CPU requests and limits, and thus there will never be a node which as 100% cpu free for you to request. 3 is simply incorrect - it may be true that for some combinations of nodes and workloads it is not possible for the Kubernetes scheduler to bin-pack efficiently, but for large clusters with diverse workloads this should not be a problem. |
