语法
{
"Type": "ALIYUN::ROS::Sleep",
"Properties": {
"DeleteDuration": Number,
"UpdateRollbackDuration": Number,
"UpdateDuration": Number,
"CreateDuration": Number,
"Triggers": Map
}
}属性
| 属性名称 | 类型 | 必须 | 允许更新 | 描述 | 约束 |
|---|---|---|---|---|---|
| DeleteDuration | Number | 否 | 是 | 删除资源前等待的时长。 | 取值范围：0~1800。 单位：秒。 |
| UpdateRollbackDuration | Number | 否 | 是 | 资源更新回滚前等待的时长。 | 仅当资源栈状态为回滚中且Triggers参数发生变化时触发。 取值范围：0~1800。 单位：秒。 |
| UpdateDuration | Number | 否 | 是 | 资源更新前等待的时长。 | 仅当资源栈状态为更新中且Triggers参数发生变化时触发。 取值范围：0~1800。 单位：秒。 |
| CreateDuration | Number | 否 | 否 | 创建资源前等待的时长。 | 取值范围：0~1800。 单位：秒。 |
| Triggers | Map | 否 | 是 | 资源更新等待和更新回滚等待的触发器。 | 在资源栈更新或回滚时，只有更新了Triggers参数，才会触发UpdateDuration和UpdateRollbackDuration。 |
返回值

无
示例
本示例中定义的资源如下：
- 一个专有网络实例（VPC）
- 一个交换机（vSwitch）
- 一个安全组（SecurityGroup）
- 一个自定义延迟时间（Sleep）
- 两个ECS实例（CenterServer和OtherServer）
本示例创建了VPC网络下的ECS实例，具体如下：
- CenterServer中有自定义脚本需要部署Nginx服务，将CenterServer中的公钥发送到OtherServer，能够使CenterServer免密登录到OtherServer，OtherServer中的脚本会访问CenterServer中的服务。
- 将CreateDuration指定为60秒，等待CenterServer内部应用部署完成，以便OtherServer成功访问CenterServer中的服务。说明 虽然CenterServer实例创建成功，但是内部的应用需要时间安装和启动，因此需要指定等待时间。
