Terraform、已创建但未正确链接的基础设施、SQS、Lambda、CloudWatch

Question

我正在尝试使用 Terraform 创建 AWS 基础设施。 SQS、Lambda 和 CloudWatch。我可以成功创建基础架构，但无法正确 link。

即当 SQS 消息为 added/sent?

时，CloudWatch 将触发一个事件到 lambda 函数

我在这里遗漏了什么吗？

}

Answer 1

我建议更改体系结构以按计划使用 SQS 消息。只需按计划将 cloudwatch 事件规则更改为运行，间隔时间较短，例如一分钟左右，并且在每次执行期间，使用 SQS API 消耗尽可能多的消息

更新

AWS 已于 2018 年 6 月将 SQS 事件源添加为 lambda 的触发器。
