How to setup Fly log shipper with Loki on Grafana Cloud

1

I’m trying to ship my logs to Loki on Grafana Cloud and I’ve set appropriate secrets however when the app is deployed I get :point_down:

 2022-06-30T22:04:40.625 app[c0ae4e53] lhr [info] 2022-06-30T22:04:40.625077Z ERROR sink{component_kind="sink" component_id=loki component_type=loki component_name=loki}:request{request_id=377}: vector_core::stream::driver: Service call failed. error=ServerError { code: 401 } request_id=377

I am not sure whether I am using the incorrect fields but this is how I set

LOKI_URL
LOKI_USERNAME
LOKI_PASSWORD

Could you please help me understand what’s wrong?

Okay, LOKI_PASSWORD should be the API key generated as described here.

Role should be at least MetricsPublisher.

After that it just worked.
