# 通过模板创建工作流
<a name="workflow-template"></a>

您可以部署用于创建工作流的 CloudFormation 堆栈和基于模板的服务器。此过程包含一个示例，您可以使用该示例来快速部署工作流程。

**创建用于创建 AWS Transfer Family 工作流程和服务器的 CloudFormation 堆栈**

1. 在 [https://console.aws.amazon.com/cloudformat](https://console.aws.amazon.com/cloudformation/) ion 上打开 CloudFormation 控制台。

1. 将以下代码保存到文件中。

1. 将以下值替换为您的实际值。
   + 将 *`workflow-execution-role-arn`* 替换为实际工作流执行角色的 ARN。例如，`arn:aws:transfer:us-east-2:111122223333:workflow/w-1234567890abcdef0`
   + 将 `arn:aws:lambda:region:account-id:function:function-name` 替换为 Lambda 函数的 ARN。例如 `arn:aws:lambda:us-east-2:123456789012:function:example-lambda-idp`。

1. 按照*AWS CloudFormation 用户指南*中的[选择 CloudFormation 堆栈模板中的使用现有模板部署堆栈](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-using-console-create-stack-template.html)的说明进行操作。

部署堆栈后，您可以在 CloudFormation 控制台的 Outputs 选项卡中**查看**有关堆栈的详细信息。该模板创建了一个使用服务管理用户的新 AWS Transfer Family SFTP 服务器和一个新的工作流程，并将该工作流与新服务器关联起来。
