验证

• 通过查看机器配置对象来查看引导镜像管理功能的当前状态：

  $ oc get machineconfiguration cluster -o yaml

  使用引导镜像引用的机器集示例

  kind: MachineConfiguration
  metadata:
    name: cluster
  # ...

• 运行以下命令来获取引导镜像版本。机器集中引导镜像的位置和格式因平台而异。但是，引导镜像总是列在 spec.template.spec.providerSpec. 参数中。

  $ oc get machinesets <machineset_name> -n openshift-machine-api -o yaml
