Formula Student telemetry base station system

This repository contains code for the base station system of a Formula Student racing team.

The system is divided in two main components: the database, based on PostgreSQL+TimescaleDB, and the dashboard, based on Grafana.

Docker is used to containerize the system.

Requirements

• Docker
• Docker Compose (optional, for older Docker versions that do not include the compose CLI command)

Usage

• Open a command-line terminal in the top-level folder of this project
• Run docker compose up (if it doesn't work, try docker-compose up; you might be using an older version of the Docker CLI)
• After setup, Grafana will be running on port 3000 and PostgreSQL will be running on port 5432
  • Grafana can be accessed at localhost:3000
  • PostgreSQL can be accessed at localhost:5432
    • Data is stored on the host machine at /data/db/, and will persist even when containers are stopped or removed

FAQ

I'm on Windows and WSL2 (Vmmem in particular) fills up my memory

Solution: limit WSL2 RAM usage via .wslconfig. See here for complete instructions: microsoft/WSL#4166 (comment)

docker.errors.DockerException: Error while fetching server API version

Solution: Docker is probably not running, check if it's running.

PostgreSQL initialization is failing

There might be some leftover files from previous Docker initializations. Run docker-compose down and then docker-compose up.
