4.2. 使用 ARM64 引导镜像在集群中添加多架构计算机器集

先决条件

• 已安装 OpenShift CLI（oc）。

流程

• 使用以下命令创建机器集，并修改 resourceID 和 vmSize 参数。此机器集将控制集群中的 ARM64 worker 节点：

  $ oc create -f arm64-machine-set-0.yaml

  使用 ARM64 引导镜像的 YAML 机器集示例

            zone: "<zone>"

  1

  将 resourceID 参数设置为 arm64 引导镜像。

  2

  将 vmSize 参数设置为安装中使用的实例类型。一些实例类型是 Standard_D4ps_v5 或 D8ps。
