红帽全球峰会4.3. 运行容器镜像准备
在执行更新前，overcloud 需要最新的 OpenStack Platform 16.1 容器镜像。这涉及执行 container_image_prepare 外部更新过程。要执行此过程，您必须针对带有 container_image_prepare 标签的任务运行 openstack overcloud external-update run 命令。这些任务执行以下操作：
- 自动准备与您的环境相关的所有容器镜像配置。
- 将相关容器镜像拉取到 undercloud 中，除非您之前禁用了此选项。
注意
如果您不使用默认的堆栈名称(overcloud)，请将堆栈名称设置为 --stack < stack_name> 选项将 & lt;stack_name > 替换为堆栈的名称。
