AWS CloudWatch Events Rule 是否支持 S3 存储桶/键名称中的任何通配符

问题描述

我正在尝试创建一个由不同 AWS 账户中 S3 存储桶中的文件更改触发的事件规则.详细说明在这里

到目前为止，该规则适用于确切的文件名，但我需要使其适用于文件名前缀.在工作示例中，文件名是一个确切的字符串，在非工作示例中，文件名是通配符.CloudWatch Events 规则 JSON 模式是否支持通配符?

工作配置:

{来源":[aws.s3"]，帐户":[1111111xxxxx"]，细节": {事件来源":[s3.amazonaws.com"]，事件名称":[放置对象"]，"requestParameters": { "bucketName": ["mybucket"], "key": ["myfile-20180301.csv"] }}}

非工作配置:

{来源":[aws.s3"]，帐户":[1111111xxxxx"]，细节": {事件来源":[s3.amazonaws.com"]，事件名称":[放置对象"]，"requestParameters": { "bucketName": ["mybucket"], "key": ["myfile-*"] }}}

解决方案

我使用 基于内容的过滤(2020 年 2 月发布)，例如 prefix.>

所以在你的情况下，解决方案应该是:

{来源":[aws.s3"]，帐户":[1111111xxxxx"]，细节": {事件来源":[s3.amazonaws.com"]，事件名称":[放置对象"]，请求参数":{"bucketName": ["mybucket"],"key": [{ "prefix": "myfile-" }]}}}

I am trying to create an event rule that is triggered by a change in a file in S3 bucket in different AWS account. Detail description is here

So far the rule works fine with exact file names, but I need to make it work with filename prefixes. In the working example, the file name is an exact string in the non-working example the file name is a wildcard. Does CloudWatch Events Rule JSON pattern supports wildcards?

Working configuration:

{
  "source": ["aws.s3"],
  "account": ["1111111xxxxx"],
  "detail": {
    "eventSource": ["s3.amazonaws.com"],
    "eventName": ["PutObject"],
    "requestParameters": { "bucketName": ["mybucket"], "key": ["myfile-20180301.csv"] }
  }
}

Non-working configuration:

{
  "source": ["aws.s3"],
  "account": ["1111111xxxxx"],
  "detail": {
    "eventSource": ["s3.amazonaws.com"],
    "eventName": ["PutObject"],
    "requestParameters": { "bucketName": ["mybucket"], "key": ["myfile-*"] }
  }
}

解决方案

I found a fancy solution for this using Content-based filtering (released in February 2020) like prefix for example.

So in your case, the solution should be:

{
  "source": ["aws.s3"],
  "account": ["1111111xxxxx"],
  "detail": {
    "eventSource": ["s3.amazonaws.com"],
    "eventName": ["PutObject"],
    "requestParameters": {
      "bucketName": ["mybucket"],
      "key": [{ "prefix": "myfile-" }]
    }
  }
}
