There are several Prometheus helm charts out there. The one I use runs a sidecar container that watches for config changes and tells Prometheus to reload the config. So you don't need the operator - there are other approaches.

But that configmap does not change by itself.

The same with annotations approach - its very limited.

Wdym the configmap doesn't change by itself? I don't want my configurations changing "magically" without my say so

The two features I need (and can get without the provider) are: 1. If I (manually, explicitly) change the configmap, prometheus can pick it up without being restarted. This is provided by the side-car container. 2. If new pods come online they are automatically detected and scraped by Prometheus. As long as they have the annotations saying: a) this pod should be scraped, b) scrape on this port, and c) scrape at this URL - then they will be scraped.
