10.3. 使用 Node Feature Discovery Operator

Node Feature Discovery（NFD）Operator 通过监视 NodeFeatureDiscovery CR 来编排运行 Node-Feature-Discovery 守护进程所需的所有资源。根据 NodeFeatureDiscovery CR，Operator 将在所需命名空间中创建操作对象（NFD）组件。您可以编辑 CR 来选择另一个 命名空间、镜像、imagePullPolicy 和 nfd-worker-conf，以及其他选项。

作为集群管理员，您可以使用 OpenShift Container Platform CLI 或 Web 控制台创建 NodeFeatureDiscovery 实例。

10.3.1. 使用 CLI 创建 NodeFeatureDiscovery 实例

作为集群管理员，您可以使用 CLI 创建 NodeFeatureDiscovery CR 实例。

先决条件

  • OpenShift Container Platform 集群
  • 安装 OpenShift CLI（oc）。
  • 以具有 cluster-admin 特权的用户身份登录。
  • 安装 NFD Operator。

流程

  1. 创建以下 NodeFeatureDiscovery 自定义资源（CR），然后在 NodeFeatureDiscovery.yaml 文件中保存 YAML： 

    apiVersion: nfd.openshift.io/v1
kind: NodeFeatureDiscovery
metadata:
  name: nfd-instance
  namespace: openshift-nfd
spec:
  instance: "" # instance is empty by default
  operand:
    namespace: openshift-nfd
    image: quay.io/openshift/origin-node-feature-discovery:4.8
    imagePullPolicy: Always

  2. 运行以下命令来创建 NodeFeatureDiscovery CR 实例： 

    $ oc create -f NodeFeatureDiscovery.yaml

验证

  • 要验证是否已创建实例，请运行： 

    $ oc get pods

    输出示例
