Ascend Device Plugin

请在任意节点执行以下步骤验证Ascend Device Plugin的安装状态。

操作步骤

  1. 通过如下命令查看K8s集群中Ascend Device Plugin的Pod，需要满足Pod的“STATUS”为Running，READY为1/1。如果集群中有多个节点安装了Ascend Device Plugin，每一个节点都需要确认。
    kubectl get pods -n kube-system -o wide | grep device-plugin

    回显示例：

    1
    ascend-device-plugin-daemonset-910-85p9v   1/1     Running   0          19h     192.168.185.251   ubuntu       <none>           <none>
  2. 通过如下命令查看K8s集群中Ascend Device Plugin的日志。
    kubectl logs -n kube-system Ascend Device Plugin组件的Pod名字

    回显示例如下，表示组件正常。

  3. 通过如下命令查看K8s中节点的详细情况。如果节点详情中的“Capacity”字段和“Allocatable”字段出现了昇腾AI处理器的相关信息，表示Ascend Device Plugin给K8s上报芯片正常，组件运行正常。
    kubectl describe node K8s中的节点名
