调用ALIYUN::ROS::Sleep延迟其他资源的操作_资源编排(ROS)-阿里云帮助中心

ALIYUN::ROS::Sleep类型用于延迟其他资源的创建、删除、更新和回滚等操作。

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


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。
