}Properties
| Property Name | Type | Required | Update allowed | Description | Constraints |
| DeleteDuration | Number | No | Yes | Wait duration before resource deletion. | Valid values: 0 to 1800. Unit: seconds. |
| UpdateRollbackDuration | Number | No | Yes | Wait duration before rollback during an update. | Takes effect only when the stack rolls back and Triggers changes. Valid values: 0 to 1800. Unit: seconds. |
| UpdateDuration | Number | No | Yes | Wait duration before resource update. | Takes effect only when the stack updates and Triggers changes. Valid values: 0 to 1800. Unit: seconds. |
| CreateDuration | Number | No | No | Wait duration before resource creation. | Valid values: 0 to 1800. Unit: seconds. |
| Triggers | Map | No | Yes | Triggers update and rollback wait behavior. | UpdateDuration and UpdateRollbackDuration take effect only when this parameter changes. |
Return values
Fn::GetAtt
None.
Examples
This example defines the following resources:
- A virtual private cloud (VPC)
- A vSwitch
- A security group
- A custom delay (Sleep)
- Two ECS instances (CenterServer and OtherServer)
The example creates ECS instances in a VPC:
- CenterServer deploys Nginx and sends its public key to OtherServer for passwordless SSH. OtherServer then accesses the Nginx service on CenterServer.
- CreateDuration is set to 60 seconds so CenterServer finishes deploying before OtherServer tries to access it.Note Instance creation completes before application installation finishes. The sleep accounts for this startup delay.
