前缀嵌套时无法在s3存储桶上应用生命周期策略

Question

I have applied a lifecycle policy on s3 bucket name ( async-download ) with prefix tmp_active_job_storage/

This works as expected when prefix is immediately after bucket name.

Below is the object key:

https://async-download.s3.amazonaws.com/tmp_active_job_storage/file_name.png

But this is not working when I introduced one folder between the bucket name and prefix. Folder name before prefix is dynamic key I can't apply rule on it.

Now modified object key is:

https://async-download.s3.amazonaws.com/1111-2222-3333-4444/tmp_active_job_storage/file_name.png

In API documentation PUT Bucket lifecycle - Amazon Simple Storage Service I can not see any support for prefix as regex.

Is there any way to achieve this?

Answer 1

Folder name before prefix is...

By definition, nothing can come "before" a key prefix. The prefix is the beginning of the object key. S3 lifecycle rules only support exact string matches, not regexes.

You need a common prefix at the beginning of all the object keys, or you need to dedicate a bucket to store these temporary files (and nothing else) so that the lifecycle policy can be applied to the entire bucket.
