Help with a log pipeline for Kubernetes.

I'm seeking your help in setting up a logging pipeline in a Kubernetes cluster. The goal is to implement observability and log aggregation in the most lightweight way possible. Additionally, I want to transform the logs into a queryable format to index and aggregate specific parts of the messages.

The stack I'm trying is Prometheus/Grafana/fluent-bit/loki. Failing in making it work

I'm looking for someone that helps me put together the right set of helm charts and configuration to make it work.

Thanks
