使用创建 AWS Secrets Manager 密钥和亚马逊文档数据库实例 AWS CloudFormation
此示例将创建一个秘密，并使用该秘密中的凭证作为用户和密码，创建一个 Amazon DocumentDB 实例。该密钥已附加用于指定谁可以访问密钥的基于资源的策略。该模板还可以从 轮换函数模板 创建 Lambda 轮换函数，并将秘密配置为协调世界时每月第一天上午 8:00 到 10:00 之间自动轮换。作为安全最佳实践，该实例位于 Amazon VPC 中。
此示例使用了 Secrets Manager 的以下 CloudFormation 资源：
有关使用创建资源的信息 AWS CloudFormation，请参阅《 AWS CloudFormation 用户指南》中的 “学习模板基础知识”。
