6.6. 镜像流映射
集成的 registry 收到新镜像时，便会创建镜像流映射并将其发送至 OpenShift Container Platform，从而提供镜像的项目、名称、标签和镜像元数据。
注意
配置镜像流映射是高级功能。
该信息用于创建新镜像（如果尚未存在）并将此镜像标记到镜像流中。OpenShift Container Platform 存储每个镜像的完整元数据，如命令、入口点和环境变量。OpenShift Container Platform 中的镜像不可变，名称最长 63 个字符。
以下镜像流映射示例结果是将镜像标记为 test/origin-ruby-sample:latest：
