VROOM Docker image

This image includes all dependencies and projects needed to successfully run an instance of vroom-express on top of vroom. Within 2 minutes you'll have a routing optimization engine running on your machine.

docker run -dt --name vroom \
    --net host \  # or set the container name as host in config.yml and use --port 3000:3000 instead, see below
    -v $PWD/conf:/conf \ # mapped volume for config & log
    -e VROOM_ROUTER=osrm \ # routing layer: osrm, valhalla or ors
    vroomvrp/vroom-docker:v1.10.0

If you want to build the image yourself, run a

docker build -t vroomvrp/vroom-docker:v1.10.0 --build-arg VROOM_RELEASE=v1.10.0 --build-arg VROOM_EXPRESS_RELEASE=v0.9.0 .

Note, you should have access to a self-hosted instance of OSRM, Valhalla or OpenRouteService for the routing server, see e.g. docker-compose.yml for an example.

Tagging

The tagging scheme follows the release convention of vroom core.

Customization

Environment variables

• VROOM_ROUTER: specifies the routing engine to be used, osrm, valhalla or ors. Default osrm.

The pre-configured host for the routing servers is localhost and port: 8080 for ORS, port: 5000 for OSRM and port: 8002 for Valhalla.

Note, the environment variable VROOM_ROUTER has precedence over the router setting in config.yml.

Volume mounting

All relevant files are located inside the container's /conf directory and can be shared with the host. These include:

• access.log: the server log for vroom-express
• config.yml: the server configuration file, which gives you full control over the vroom-express configuration. If you need to edit the configuration, run docker restart vroom to restart the server with the new settings.

Add a -v $PWD/vroom-conf:/conf to your docker run command.

Build arguments

If you prefer to build the image from source, there are 2 build arguments:

• VROOM_RELEASE: specifies VROOM's git branch, commit hash or release (e.g. v1.10.0) to install in the container
• VROOM_EXPRESS_RELEASE: specifies vroom-express's git branch, commit hash or release (e.g. v0.9.0) to install in the container

Note, not all versions are compatible with each other

docker-compose

We include a docker-compose.yml in the project to get you started easily.

docker-compose up -d will pull the latest vroom-docker image and the latest openrouteservice docker image.

Routing Server

You have the option to use OSRM, Valhalla or OpenRouteService. However, the proper setup in Docker or docker-compose depends on how you run the routing server.

Routing server in local Docker container

If you started the routing layer in a separate Docker container via docker run, you'll have to start the vroom container on the host network by adding --net host. The disadvantage is that you'll have to assign vroom-express configured port on the host machine. If port 3000 is already occupied on your machine, configure a different port in config.yml.

Alternatively you can add both containers to a private Docker network and change the routing server host(s) to the routing server container name(s) in config.yml before restarting the vroom container. However, the concepts involved are beyond the scope of this project.

Whole stack started with docker-compose

Make sure to include a network_mode: host in your vroom service section, which will have the same effect as adding --net host to a docker run statement.

Also here the alternative is to create a private Docker network, where your services only publish the ports needed to run the stack. Note, you'll have to change the host(s) in config.yml to the service name(s) defined in docker-compose.yml.

Routing server on a remote server

In this case, you'll have to edit the mapped config.yml to include the host and port you published the routing server on.
