将数据附加到S3对象 [英] Append data to an S3 object

问题描述

假设我有一台想要写入存储在S3存储桶中的特定日志文件的机器.

Let's say that I have a machine that I want to be able to write to a certain log file stored on an S3 bucket.

因此，机器需要具有对该存储桶的写入功能，但是，我不希望它具有覆盖或删除该存储桶中的任何文件(包括我要写入的文件)的能力.

So, the machine needs to have writing abilities to that bucket, but, I don't want it to have the ability to overwrite or delete any files in that bucket (including the one I want it to write to).

因此，基本上，我希望我的机器只能将数据追加到该日志文件，而不覆盖它或下载它.

So basically, I want my machine to be able to only append data to that log file, without overriding it or downloading it.

有没有一种方法可以配置S3使其正常工作?也许有一些IAM策略可以附加到它上，这样它就可以像我想要的那样工作了?

Is there a way to configure my S3 to work like that? Maybe there's some IAM policy I can attach to it so it will work like I want?

推荐答案

不幸的是，你不能.

S3没有追加"操作. ^* 上传对象后，就无法对其进行修改.您唯一的选择是上传一个新对象来替换它，这不符合您的要求.

S3 doesn't have an "append" operation.^* Once an object has been uploaded, there is no way to modify it in place; your only option is to upload a new object to replace it, which doesn't meet your requirements.
