红帽全球峰会4.2. 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。这包括执行 container_image_prepare 外部更新过程。要执行这个过程，您必须针对带有 container_image_prepare 标签标记的任务运行 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，除非您之前禁用了这个选项。
注意
如果不使用默认堆栈名称(overcloud)，请使用 --stack <stack_name> 选项替换 < ;stack_name& gt; 选项设置堆栈名称，并将 < stack_name > 替换为您的堆栈的名称。
流程
Source
stackrc文件：$ source ~/stackrc
针对带有
container_image_prepare标签的任务运行openstack overcloud external-update run命令：$ openstack overcloud external-update run --stack <stack_name> --tags container_image_prepare
