README

Adapter for external geocoding services with caching, monitoring, metrics etc. Has built-in support for timezone queries (resolve coordinates to timezone) implemented using amazing Brad Fitzpatrick's library. Supports Google's Geocoding API and Opencage for now.

Usage

Docker image

docker run \
    -p 8080:8080 -p 9092:9092 \
    -e REDIS_HOST=redis \
    -e GOOGLE_API_KEY_SERVER=<your-google-key> \
    -e OPENCAGE_API_KEY=<your-opencage-key> \
    rentberry:geocoder

This will start geocoding service that listens for grpc connections on port 8080 and exposes prometheus metrics on /metrics on port 9092
