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

  1. 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
    Copy to Clipboard Toggle word wrap

    输出示例

    NAME                                      READY   STATUS    RESTARTS   AGE
nfd-controller-manager-8698c88cdd-t8gbc   2/2     Running   0          2m
    Copy to Clipboard Toggle word wrap

  2. 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'`
    Copy to Clipboard Toggle word wrap

  3. 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"
    Copy to Clipboard Toggle word wrap

  4. 运行以下命令来创建 'NodeFeatureDiscovery' 实例： 

    $ oc create -f nfd-instance.yaml
    Copy to Clipboard Toggle word wrap

    输出示例

    nodefeaturediscovery.nfd.openshift.io/nfd-instance created
    Copy to Clipboard Toggle word wrap

  5. 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
    Copy to Clipboard Toggle word wrap

    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
    Copy to Clipboard Toggle word wrap

  6. 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")))'
