Loki is complaining about missing config for compactor. Has something changed since this was posted?

@pinpox You can see another example config here - https://github.com/grafana/loki/blob/main/cmd/loki/loki-local-config.yaml

Thanks!

I managed to get this config working just by adding the below.

compactor:
  working_directory: /var/lib/loki
  shared_store: filesystem
  compactor_ring:
    kvstore:
      store: inmemory

You can probably cut the config down altogether by using the common key. I'll give that a go and post my result here if I have any luck with that.

Oh and thanks to Xe for writing this!
