+ k8s 1.23.9

安装amd的内核驱动

wget https://repo.radeon.com/amdgpu-install/22.20.3/ubuntu/jammy/amdgpu-install_22.20.50203-1_all.deb
sudo apt install ./amdgpu-install_22.20.50203-1_all.deb

kubectl create -f https://raw.githubusercontent.com/RadeonOpenCompute/k8s-device-plugin/master/k8s-ds-amdgpu-dp.yaml

工作负载 pod 中调用amd的gpu demo

resources.limits中加入一个对应的标识就行了

apiVersion: v1
kind: Pod
metadata:
  name: alexnet-tf-gpu-pod
  labels:
    purpose: demo-tf-amdgpu
spec:
  containers:
    - name: alexnet-tf-gpu-container
      image: rocm/tensorflow:latest
      workingDir: /root
      env:
      - name: HIP_VISIBLE_DEVICES
        value: "0" # # 0,1,2,...,n for running on GPU and select the GPUs, -1 for running on CPU
      command: ["/bin/bash", "-c", "--"]
      args: ["python3 benchmarks/scripts/tf_cnn_benchmarks/tf_cnn_benchmarks.py --model=alexnet; trap : TERM INT; sleep infinity & wait"]
      resources:
        limits:
          amd.com/gpu: 1 # requesting a GPU
