红帽全球峰会9.6. 下载 RHCOS 集群镜像
安装程序需要 Red Hat Enterprise Linux CoreOS (RHCOS) 镜像来安装集群。在可选时，在部署前下载 Red Hat Enterprise Linux CoreOS (RHCOS) 会删除创建集群时访问互联网的需要。
使用安装程序查找并下载 Red Hat Enterprise Linux CoreOS (RHCOS) 镜像。
先决条件
- 运行安装程序的主机可以访问互联网。
流程
进入包含安装程序的目录并运行以下命令：
$ ./openshift-install coreos print-stream-json使用命令的输出来查找 IBM Cloud® 镜像的位置。
