This repo contains the TUM-GI IoT Stack consists of:

• FROST-Server: Access and store sensor data and IoT metadata based on the SensorThingsAPI.
• Grafana: Visualize timeseries and other data in the Browser.
• Node-RED: Connect and translate between sensor data platforms and the SensorThingsAPI.
• Caddy: Reverse proxy and automated SSL provider

• Docker: https://www.docker.com/
• Docker compose: https://docs.docker.com/compose/cli-command/#installing-compose-v2
• Docker swarm: https://docs.docker.com/engine/swarm/
  • Run docker swarm --init to initialize as single node swarm on your Docker host
  • For more advanced setups, e.g. with multiple nodes see: https://docs.docker.com/engine/swarm/

docker volume create caddy_config
docker volume create caddy_data
docker volume create grafana_data
docker volume create grafana_config
docker volume create frost_db_data
docker volume create nodered_data

First, clone this repo and switch to the cloned folder. The folder name will be used as name for this stack in Docker.

git clone https://github.com/tum-gis/tum-gis-iot-stack-basic.git myStackname
cd myStackname

Edit .env according to your needs. Make sure to set DOMAIN to your DNS name, e.g. mydomain.com. For local testing use localhost. ADMIN_EMAIL is only used for notifications regarding automated SSL certificate management.

Use the *_SUBPATH variables to set the url subpath, where the services should be available. For instance, if you set FROST_SUBPATH to /frost the FROST-Server will be available at: https://DOMAIN/FROST_SUBPATH, https://mydomain.com/frost.

After the configuration is finished, you can bring up the stack using docker compose.

docker compose up --build -d

When the stack has fully booted, the services are available at:

• FROST-Server: https://DOMAIN/FROST_SUBPATH
• Node-RED: https://DOMAIN/NODERED_SUBPATH
• Grafana: https://DOMAIN/GRAFANA_SUBPATH

Run docker compose ps to check the health status of the stack. All services should be listed as healthy.

❯ docker compose ps
