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

问题描述

假设我有一台机器，我希望能够写入存储在 S3 存储桶上的某个日志文件.

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，机器需要具有写入该存储桶的能力，但是，我不希望它能够覆盖或删除该存储桶中的任何文件(包括我希望它写入的文件).

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).

所以基本上，我希望我的机器能够只将数据附加到该日志文件中，而不会覆盖它或下载它.

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

有没有办法将我的 S3 配置为这样工作?也许我可以附加一些 IAM 政策，以便它可以像我想要的那样工作?

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

很遗憾，您不能.

S3 没有追加"操作.^* 一旦一个对象被上传，就无法修改它；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.
