Loki S3 bucket configuration

Hi everyone,
I have successfully set up loki and s3 bucket, here is a config snippet - I am using loki-stack helm chart

          bucketnames: test_bucket
          region: us-east-2
          s3forcepathstyle: true

I do not want to pass a full bucket but instead use a folder within a bucket. I tried so far

          bucketnames: test_bucket/folder

But that doesnt work.
Anyone knows how to configure it properly?

I don’t believe that’s possible. You should have dedicated S3 bucket for Loki, there is no reason not to since there is no cost for just having a new S3 bucket.

Got it, thanks for the help.
Its more for organization purpose than anything else.
I thought I saw somewhere a potential solution using prefix.
