4.3. 使用 Node Feature Discovery 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
     topologyupdater: false # False by default
     operand:
       image: registry.redhat.io/openshift4/ose-node-feature-discovery:v4.10
       imagePullPolicy: Always
     workerConfig:
       configData: |
         core:

           sleepInterval: 60s
         #  sources: [all]
         #  klog:
         #    addDirHeader: false
         #    alsologtostderr: false
         #    logBacktraceAt:
         #    logtostderr: true
         #    skipHeaders: false
         #    stderrthreshold: 2
         #    v: 0
         #    vmodule:
         ##   NOTE: the following options are not dynamically run-time configurable
         ##         and require a nfd-worker restart to take effect after being changed
         #    logDir:
         #    logFile:
         #    logFileMaxSize: 1800
         #    skipLogHeaders: false
         sources:
           cpu:
             cpuid:
         #     NOTE: whitelist has priority over blacklist
               attributeBlacklist:

   Copy to Clipboard Toggle word wrap

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

   $ oc create -f NodeFeatureDiscovery.yaml

   Copy to Clipboard Toggle word wrap

流程

1. 进入到 Operators Installed Operators 页面。
2. 查找 Node Feature Discovery，并在 Provided APIs 下看到一个方框。
3. 单击 Create instance。
4. 编辑 NodeFeatureDiscovery CR 的值。
5. 点 Create。
