IoT Hub

A docker swarm-ed Hub for recieving, storing and showing IoT data. It relies on a Mosquitto broker for recieving the messages, InfluxDB for storage and Grafana for showing it.

System requirements

The swarm has been tested on Linux version of Docker 18.01.

Run

In a bash, a first run should use:

make

or:

./run.sh

It'll initiate all of the internal assets.

For subsequent runs, use:

make deploy

To stop the swarm, use:

make rm

Implementation

• The MQTT broker uses the official Eclipse image. It exposes the default port to all IPs and waits for messages.
• The adaptor/MQTT subscriber is written in Python. It does the subscription and listens to all the topics (#). It is log enabled through an environment variable. The image was uploaded to DockerHub, for docker stach deploy command.
• The official InfluxDB docker image is used for data storage. At the initial setup, a default database (called "iot") is created.
• For visual feedback, Grafana is used. All the neccessary configurations have been made and saved in grafana subfolder. It acceses them through a bind mount. Though in future versions the config should be stored as JSON format.
