For this file <https://github.com/SigNoz/signoz/blob/28bf2fe3f7c0b013685921c9d4bfdb254ac42e81/deploy/docker/clickhouse-setup/prometheus.yml#L2|here>, what files are needed to run the query-service within docker? Do I need `alerts.yml` at all or can i omit the files altogether? From my understanding the query-service acts as the prometheus server and stores the alerts in the SQLite DB on the filesystem? Also I noticed `alertmanager.yml` seems to be unused, is this needed anywhere?

Also does SigNoz support environment vars in this file as I want to be able to replace the clickhouse domain, user, password without exposing that in the file I mount into the container (`prometheus.yml`)

Hi <@U03D61XNV43>  alerts related yaml files are no longer required from v.8.x 

i don't think the prometheus yaml would not support env vars

what is your use case 

Doesn’t seem it supports env vars: <https://github.com/prometheus/prometheus/issues/2357>

My use case is not to hardcode secrets and DNS names into config files I have setup in Github and instead have that injected at runtime via Cloudformation.
