overpass-immu-docker

overpass-immu-docker is a Docker container that enables local querying of OpenStreetMap (OSM) data using the Overpass API, eliminating the dependency on public Overpass API servers.

OSM data is ingested from .pbf files into the Overpass database format and stored on the host filesystem via Docker volumes, keeping the container itself stateless and immutable.
