5.3. 使用 BMO 在用户置备的集群中置备新主机

流程

1. 创建 Secret CR 和 BareMetalHost CR。

   1. 将以下 YAML 保存到 bmh.yaml 文件中：

      ---
      apiVersion: v1
      kind: Secret
      metadata:
        name: worker1-bmc
        namespace: openshift-machine-api
      type: Opaque
      data:
        username: <base64_of_uid>
        password: <base64_of_pwd>
      ---
      apiVersion: metal3.io/v1alpha1
      kind: BareMetalHost
      metadata:
        name: worker1
        namespace: openshift-machine-api
      spec:
        bmc:
          address: <protocol>://<bmc_url> 

      1

      
          credentialsName: "worker1-bmc"
        bootMACAddress: <nic1_mac_address>
        externallyProvisioned: false 

      2

      
        customDeploy:
          method: install_coreos
        online: true
        userData:
          name: worker-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 BareMetalHost 自定义资源中的 spec.externallyProvisioned 规格设置为 false。默认值为 false。

2. 运行以下命令来创建裸机主机对象：

   $ oc create -f bmh.yaml

   Copy to Clipboard Toggle word wrap

   输出示例

   secret/worker1-bmc created
   baremetalhost.metal3.io/worker1 created

   Copy to Clipboard Toggle word wrap

3. 批准所有证书签名请求 (CSR)。

   1. 运行以下命令验证主机的置备状态是否为 provisioned：

      $ oc get bmh -A

      Copy to Clipboard Toggle word wrap

      输出示例

      NAMESPACE               NAME          STATE                    CONSUMER   ONLINE   ERROR   AGE
      openshift-machine-api   controller1   externally provisioned              true             5m25s
      openshift-machine-api   worker1       provisioned                         true             4m45s

      Copy to Clipboard Toggle word wrap

   2. 运行以下命令，获取待处理的 CSR 列表：

      $ oc get csr

      Copy to Clipboard Toggle word wrap

      输出示例

      NAME        AGE   SIGNERNAME                                    REQUESTOR                                         REQUESTEDDURATION CONDITION
      csr-gfm9f   33s   kubernetes.io/kube-apiserver-client-kubelet   system:serviceaccount:openshift-machine-config-o
      perator:node-bootstrapper   <none>              Pending

      Copy to Clipboard Toggle word wrap

   3. 运行以下命令来批准 CSR：

      $ oc adm certificate approve <csr_name>

      Copy to Clipboard Toggle word wrap

      输出示例

      certificatesigningrequest.certificates.k8s.io/<csr_name> approved

      Copy to Clipboard Toggle word wrap
