 The flag `-v "${PWD}:/data"` creates the directory `/data` inside the docker container and makes the current working directory `"${PWD}"` available there. The file `/data/berlin-latest.osm.pbf` inside the container is referring to `"${PWD}/berlin-latest.osm.pbf"` on the host.

 Note there is no `berlin-latest.osrm` file, but multiple `berlin-latest.osrm.*` files, i.e. `berlin-latest.osrm` is not file path, but "base" path referring to set of files and there is an option to omit this `.osrm` suffix completely(e.g. `osrm-partition /data/berlin-latest`).
