GPU资源限制

Question

我在限制Pods对群集中可用GPU的访问时遇到麻烦。

这是我的.yaml：

kind: Pod
metadata:
  name: train-gpu
  spec:
  containers:
  - name: train-gpu
    image: index.docker.io/myprivaterepository/train:latest
    command: ["sleep"]
    args: ["100000"]
    resources:
      limits:
        nvidia.com/gpu: 1 # requesting 1 GPU

当我在此容器中运行nvidia-smi命令时，所有的GPU都会显示出来，而不仅仅是1个。

任何建议将不胜感激。

一些有用的信息：
