红帽全球峰会12.5. 获取 AWS Marketplace 镜像
如果要使用 AWS Marketplace 镜像部署 OpenShift Container Platform 集群，您必须首先通过 AWS 订阅。订阅提供的提供的 AMI ID 可让您使用安装程序用来部署计算节点的 AMI ID。
注意
您应该只修改计算机器的 RHCOS 镜像以使用 AWS Marketplace 镜像。control plane 机器和基础架构节点不需要 OpenShift Container Platform 订阅，且默认使用公共 RHCOS 默认镜像，这不会对 AWS bill 造成订阅成本。因此，您不应该修改集群默认引导镜像或 control plane 引导镜像。将 AWS Marketplace 镜像应用到它们时，会生成无法恢复的额外许可成本。
先决条件
- 有 AWS 账户购买的产品。此帐户不必与用于安装集群的帐户相同。
流程
- 从 AWS Marketplace 完成 OpenShift Container Platform 订阅。
-
记录特定 AWS 区域的 AMI ID。如果使用 CloudFormation 模板来部署计算节点，则必须使用 AMI ID 值更新
