Just assume, we have a only one node with 60 GB memory. Pod A scheduled with request of 10 GB and no limit. After some time, it start using 55 GB ( ignore systems reserves for now). system now has only left with 5 GB free. If new podB scheduled with request of 10GB, what is systems behavior? * Will it place Pod A and evict PodB softly since it can’t accommodate both pods on same node? Kubelet should evict pod A because it is using a higher % of memory than it requested. * * Scheduling fail to pod B since it can’t accommodate since node doesn’t enough requested memory? No, scheduling should not fail. Scheduler knows only requests and from requests angle scheduler is fine. * For more details you might want to refer https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/pod-preemption.md#preemption---eviction-workflow -- Srinivas Kotaru _______________________________________________ dev mailing list [email protected]<mailto:[email protected]> http://lists.openshift.redhat.com/openshiftmm/listinfo/dev
