5.4. 可选：使用 BMO 管理用户置备的集群中的现有主机

流程

1. 创建 Secret CR 和 BareMetalHost CR。

   1. 将以下 YAML 保存到 controller.yaml 文件中：

      ---
      apiVersion: v1
      kind: Secret
      metadata:
        name: controller1-bmc
        namespace: openshift-machine-api
      type: Opaque
      data:
        username: <base64_of_uid>
        password: <base64_of_pwd>
      ---
      apiVersion: metal3.io/v1alpha1
      kind: BareMetalHost
      metadata:
        name: controller1
        namespace: openshift-machine-api
      spec:
        bmc:
          address: <protocol>://<bmc_url> 

      1

      
          credentialsName: "controller1-bmc"
        bootMACAddress: <nic1_mac_address>
        customDeploy:
          method: install_coreos
        externallyProvisioned: true 

      2

      
        online: true
        userData:
          name: controller-user-data-managed
          namespace: openshift-machine-api

      Copy to Clipboard Toggle word wrap

      1

      您只能使用支持虚拟介质网络引导的裸机主机驱动程序，如 redfish-virtualmedia 和 idrac-virtualmedia。

      2

      您必须将值设为 true，以防止 BMO 重新置备裸机控制器主机。

2. 运行以下命令来创建裸机主机对象：

   $ oc create -f controller.yaml

   Copy to Clipboard Toggle word wrap

   输出示例

   secret/controller1-bmc created
   baremetalhost.metal3.io/controller1 created

   Copy to Clipboard Toggle word wrap
