本文以批量在ECS实例中执行命令为例,介绍如何在系统运维管理 OOS(CloudOps Orchestration Service)控制台新建自定义模板。
登录系统运维管理控制台。
选择自动化任务 > 自定义任务模板,单击创建模板。
使用示例模板创建或使用本地文件创建。
示例模板选择批量执行命令,单击下一步。
如果您已经预先编写好批量执行命令YAML或JSON格式的模板文件,您可以选择使用本地文件创建,上传后,单击下一步。

(可选)获取ECS实例已经预置,如需修改可以在模板参数-targets部分进行配置。
说明选择需要执行命令的 ECS 实例,在创建执行时填写相关信息。详情,请参见创建执行。
在命令内容区域,编辑脚本内容,单击创建模板。
填写模板名称,单击完成创建。
