kubernetes - kubernetes 上的 cpu 和 gpu 资源配额

Question

团队，
我无法理解“二手”与“硬”设置限制。当我设置 requests.nvidia.com/gpu: "1"时，使用部分如何显示 requests.nvidia.com/gpu: "640" ？和 request.cpu 一样是 1 但显示 80？

    requests.nvidia.com/gpu: "640"

Resourcequotas 在创建新对象时强制执行，它对现有 pod 没有影响，它不会尝试破坏已经运行的 pod。
另外消耗的cpu单位是millicores 1000一个核心。
