Use OSRM instead of Google Maps

1. How to install and use OSRM backend?

1.1 Why we should use OSRM instead of Google Maps.

Currently, API of Google maps only support for a response from request, thus we must futher add money for many requests in production. Thus, a OSRM solution is open-source project which help for personal projects (mobile/ web) or small projects without add more money.

1.2 OSRM solution.

OSRM is Open Source Routing Machine.

Step 1: Download maps: http://download.geofabrik.de/index.html

Note: - Use ``.osm`` file
      - docker-hub: https://hub.docker.com/r/osrm/osrm-backend/
      - Github link: https://github.com/Project-OSRM/osrm-backend

Step 2: Get Vietnam osm data from Geofabrik website

$wget http://download.geofabrik.de/asia/vietnam-latest.osm.bz2  # For Vietnam

Step 3: Extract maps data via docker command

$docker run -t -i -p 5000:5000 -v "${PWD}:/data" osrm/osrm-backend osrm-extract -p /opt/car.lua /data/vietnam-latest.osm

Step 4: Run partition and customize along with other containers

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

$docker run -t -i -v $(pwd):/data osrm/osrm-backend osrm-customize /data/vietnam-latest.osrm

Step 5: Launch a routed map server (online map server)

$docker run -t -i -p 5000:5000 -d -v $(pwd):/data osrm/osrm-backend osrm-routed --algorithm mld /data/vietnam-latest.osrm

$docker ps -a

Step 5: Check running osrm map server

2. Build OSRM front-end.

$docker run -p 9966:9966 osrm/osrm-frontend

Result:

Let’s enjoy with OSRM !!!
