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](https://github.com/openbikesensor/portal/issues/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 does not use submodules anymore:

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

Production setup

There is a guide for a deployment based on docker at docs/production-deployment.md. Lots of non-docker deployment strategies 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.

Upgrading and migrating is described in UPGRADING.md for each version.

Migrating (Production)

Migrations are done with Alembic, please refer to its documentation for help. Most of the time, running this command will do all the migrations you need:

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

This command is equivalent to running migrations through alembic, then regenerating the SQL functions that compute vector tiles directly in the database:

# equivalent to the above command, you don't usually run these
docker-compose run --rm api alembic upgrade head
docker-compose run --rm api tools/prepare_sql_tiles

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. Create a file at api/config.overrides.py with the secret in it:

  KEYCLOAK_CLIENT_SECRET="your secret here"

  You can use this file in development mode to change settings without editing the git-controlled default file at api/config.dev.py. Options in this file take precendence.

• 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, run the upgrade command to generate the database schema:

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

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

You should also import OpenStreetMap data now.

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 done with Alembic, please refer to its documentation for help. Most of the time, running this command will do all the migrations you need:

docker-compose run --rm api alembic upgrade head

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 :)

Connecting to the PostgreSQL database

If you need to connect to your development PostgreSQL database, you should install psql locally. The port 5432 is already forwarded, so you can connect with:

psql -h localhost -U obs -d obs

The password is obs as well.
