Use Querier Front-End to talk to your own prometheus query API

[srijan55]

I have setup my own prometheus query endpoint (with custom data source). Is it possible to setup only cortex front-end which talks to this endpoint instead of its own querier and gives me all the goodness of query caching etc.

Hello. Yes, that is possible. Please take a look here: https://cortexmetrics.io/docs/configuration/prometheus-frontend/

The trick is to set downstream_url field in the frontend section and only start query-frontend component from Cortex (using target field).
