Loki is an amazing log aggregation tool, and we’ve fully migrated our services here at Vokke. We’re all in. That said, we run Loki and the corresponding Grafana stack on our own infrastructure, and the setup was a little painful, primarily because of a lack of consistent documentation for the most recent version.

So here’s the config that worked for us, using a local MinIO object store. If you need a hand, feel free to email me at [email protected] and I’ve see if I can help!
