I have a question regarding setting up **Reverse Geocoding** (to get cities/countries stats). I understand that I need to define the Photon URL via environment variables in `docker-compose.yml`.

Could you confirm where exactly these variables (`PHOTON_API_HOST` etc.) should be placed? Do I need to add them under **both** the `dawarich_app` service AND the `dawarich_sidekiq` service to ensure the background jobs can see them, or is adding them to `dawarich_app` sufficient?

Thanks again for the help!

They should be placed in both services, you can use default compose file as a reference

Hi @Freika it is possible to set the Photon Host with : if th Phonton Container is on the same host how Dawarich is?

Should be, but if you mean running under same docker container, I haven’t tried it
