红帽全球峰会5.4. 配置 NFD Operator
Node Feature Discovery（NFD）Operator通过将节点标记为硬件特定信息来管理 OpenShift Container Platform 集群中硬件功能和配置的检测。NFD 使用特定于节点的属性标记主机，如 PCI 卡、内核、操作系统版本等。
先决条件
- 已安装 NFD Operator。
流程
运行以下命令，验证 Operator 是否已安装并运行
openshift-nfd命名空间中的 pod：$ oc get pods -n openshift-nfd输出示例
NAME READY STATUS RESTARTS AGE nfd-controller-manager-8698c88cdd-t8gbc 2/2 Running 0 2m在 NFD 控制器运行时，生成
NodeFeatureDiscovery实例，并将其添加到集群中。NFD Operator 的
ClusterServiceVersion规格提供默认值，包括作为 Operator 有效负载一部分的 NFD 操作对象镜像。运行以下命令来检索其值：$ NFD_OPERAND_IMAGE=`echo $(oc get csv -n openshift-nfd -o json | jq -r '.items[0].metadata.annotations["alm-examples"]') | jq -r '.[] | select(.kind == "NodeFeatureDiscovery") | .spec.operand.image'`可选：在默认的
deviceClassWhiteList字段中添加条目来支持更多网络适配器，如 NVIDIA BlueField DPUs。apiVersion: nfd.openshift.io/v1 kind: NodeFeatureDiscovery metadata: name: nfd-instance namespace: openshift-nfd spec: instance: '' operand: image: '${NFD_OPERAND_IMAGE}' servicePort: 12000 prunerOnDelete: false topologyUpdater: false workerConfig: configData: | core: sleepInterval: 60s sources: pci: deviceClassWhitelist: - "02" - "03" - "0200" - "0207" - "12" deviceLabelFields: - "vendor"运行以下命令来创建 'NodeFeatureDiscovery' 实例：
$ oc create -f nfd-instance.yaml输出示例
nodefeaturediscovery.nfd.openshift.io/nfd-instance created运行以下命令，通过查看
openshift-nfd命名空间中的 pod 来验证实例是否已启动并正在运行：$ oc get pods -n openshift-nfd输出示例
NAME READY STATUS RESTARTS AGE nfd-controller-manager-7cb6d656-jcnqb 2/2 Running 0 4m nfd-gc-7576d64889-s28k9 1/1 Running 0 21s nfd-master-b7bcf5cfd-qnrmz 1/1 Running 0 21s nfd-worker-96pfh 1/1 Running 0 21s nfd-worker-b2gkg 1/1 Running 0 21s nfd-worker-bd9bk 1/1 Running 0 21s nfd-worker-cswf4 1/1 Running 0 21s nfd-worker-kp6gg 1/1 Running 0 21s等待短暂的时间，然后验证 NFD 是否已向节点添加标签。NFD 标签使用
feature.node.kubernetes.io前缀，以便您可以轻松过滤它们。$ oc get node -o json | jq '.items[0].metadata.labels | with_entries(select(.key | startswith("feature.node.kubernetes.io")))' {
