Loki + S3 (minIO) configuration

Question

I'm tryig to configure Loki on separate VM with S3 (minIO) as a object store, using docker-composer.

The minIO/s3 bucket is public and addiotionaly I have added r/w permission to it.

There are no errors in logs.

The file loki_cluster_seed.json successfully created, but no index/chunks dirs

Loki version 2.8.2

Can someone help me to find out the issue?

My configuration.
