Pre-process the extract with the car profile and start a routing engine HTTP server on port 5000

docker run -t -v "$(pwd):/data" osrm/osrm-backend osrm-extract -p /opt/car.lua /data/berlin-latest.osm.pbf
docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-extract -p /opt/car.lua /data/berlin-latest.osm.pbf

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 `"$(pwd)/berlin-latest.osm.pbf"` on the host.
The flag `-v "${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.

docker run -t -v "$(pwd):/data" osrm/osrm-backend osrm-partition /data/berlin-latest.osrm

docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-customize /data/berlin-latest.osrm

Note that `berlin-latest.osrm` has a different file extension.
