OpenBikeSensor Portal

This repository contains the source code required to run the OpenBikeSensor data collection portal. It is separated into components:

• api: The backend service, written in Python 3 with Sanic, SQLAlchemy, and a PostgreSQL/PostGIS database for storage. It also depends highly on OpenMapTiles to generate vector tiles of the data.
• frontend: A React single-page application that allows access to the data, provides summaries and visualizations, and lets users adjust settings and manage and publish their tracks.

Check out the Architecture Documentation for more details on what parts the whole application is made of.

This project follows semantic versioning. Refer to issue #44 for a description of what that means for our project and what is considered the public interface.

Clone the Project

First of all, you must clone this project. This project uses submodules, thus ensure, that they are cloned as well:

git clone --recursive https://github.com/openbikesensor/portal

# ... or if you forgot the --recursive argument, you can run this in the
# repository's directory later:
git submodule update --init --recursive

Production setup

There is a guide for a deployment based on docker in the deployment folder. Lots of non-docker deployment strategy are possible, but they are not "officially" supported, so please do not expect the authors of the software to assist in troubleshooting.

This is a rather complex application, and it is expected that you know the basics of deploying a modern web application securely onto a production server. We are sorry that we cannot guide you through all the details of that, as we just don't have the capacities to do so. Please research the respective topics first. If you struggle with application-specific issues, please let us know, we might be able to assist with those.

Please note that you will always need to install your own reverse proxy that terminates TLS for you and handles certificates. We do not support TLS directly in the application, instead, please use this prefered method.

Migrating (Production)

Migrations are not implemented yet. Once we need them, we'll add them and document the usage here.

Upgrading from v0.2 to v0.3

After v0.2 we switched the underlying technology of the API and the database. We now have no more MongoDB, instead, everything has moved to the PostgreSQL installation. For development setups, it is advised to just reset the whole state (remove the local folder) and start fresh. For production upgrades, please follow the relevant section in UPGRADING.md.

Development setup

We've moved the whole development setup into Docker to make it easy for everyone to get involved.

Install docker

Please install Docker Engine as well as Docker Compose onto your machine.

Then clone the repository as described above.

Configure Keycloak

Login will not be possible until you configure the keycloak realm correctly. Boot your keycloak instance:

docker-compose up -d keycloak

Now navigate to http://localhost:3003/ and follow these steps:

• Click Administration Console and log in with admin / admin.
• Hover over the realm name on the top left and click Add realm.
• Name the Realm obs-dev (spelling matters) and create it.
• In the sidebar, navigate to Configure → Clients, and click Create on the top right.
• Client ID should be portal. Click Save.
• In the Tab Settings, edit the new client's Access Type to confidential and enter as Valid Redirect URIs: http://localhost:3000/login/redirect, then Save
• Under Credentials, copy the Secret and paste it into api/config.dev.py as KEYCLOAK_CLIENT_SECRET. Please do not commit this change to git.
• In the sidebar, navigate to Manage → Users, and click Add user on the top right.
• Give the user a name (e.g. test), leave the rest as-is.
• Under the tab Credentials, choose a new password, and make it non-temporary. Click Set Password.

We are going to automate this process. For now, you will have to repeat it every time you reset your keycloak settings, which are stored inside the PostgreSQL as well. Luckily, the script api/tools/reset_database.py does not affect the state of the keycloak database, so this should be rather rare.

Prepare database

Start the PostgreSQL database:

docker-compose up -d postgres

The first time you start postgres, a lot of extensions will be installed. This takes a while, so check the logs of the docker container until you see:

PostgreSQL init process complete; ready for start up.

If you don't wait long enough, the following commands might fail. In this case, you can always stop the container, remove the data directory (local/postgres) and restart the process.

Next, initialize an empty database, which applies the database schema for the application:

docker-compose run --rm api tools/reset_database.py

To be able serve dynamic vector tiles from the API, run the following command once:

docker-compose run --rm api tools/prepare_sql_tiles.py

You might need to re-run this command after updates, to (re-)create the functions in the SQL database that are used when generating vector tiles.

You should also import OpenStreetMap data now, see below for instructions.

Boot the application

Now you can run the remaining parts of the application:

docker-compose up -d --build api worker frontend

Your frontend should be running at http://localhost:3001 and the API at http://localhost:3000 -- but you probably only need to access the frontend for testing.

Migrating (Development)

Migrations are not implemented yet. Once we need them, we'll add them and document the usage here.

Import OpenStreetMap data

You need to import road information from OpenStreetMap for the portal to work. This information is stored in your PostgreSQL database and used when processing tracks (instead of querying the Overpass API), as well as for vector tile generation. The process applies to both development and production setups. For development, you should choose a small area for testing, such as your local county or city, to keep the amount of data small. For production use you have to import the whole region you are serving.

• Install osm2pgsql.

• Download the area(s) you would like to import from GeoFabrik.

• Import each file like this:

  osm2pgsql --create --hstore --style api/roads_import.lua -O flex \
    -H localhost -d obs -U obs \
    path/to/downloaded/myarea-latest.osm.pbf 
  

You might need to adjust the host, database and username (-H, -d, -U) to your setup, and also provide the correct password when queried. For the development setup the password is obs. For production, you might need to expose the containers port and/or create a TCP tunnel, for example with SSH, such that you can run the import from your local host and write to the remote database.

The import process should take a few seconds to minutes, depending on the area size. A whole country might even take one or more hours. You should probably not try to import planet.osm.pbf.

You can run the process multiple times, with the same or different area files, to import or update the data. You can also truncate the road table before importing if you want to remove outdated road information.

Refer to the documentation of osm2pgsql for assistance. We are using "flex mode", the provided script api/roads_import.lua describes the transformations and extractions to perform on the original data.

Troubleshooting

If any step of the instructions does not work for you, please open an issue and describe the problem you're having, as it is important to us that onboarding is super easy :)
