IoT Prototyping Backend

Overview

This project is a backend solution for prototyping Internet of Things (IoT) services. It leverages the power of Docker containers to easily integrate Grafana, InfluxDB, and Node-RED into a seamless, scalable, and robust backend system. The solution aims to provide rapid prototyping capabilities for IoT applications that need real-time data visualization, storage, and workflow automation.

Features

• Eclipse Mosquitto: MQTT broker
• Grafana: Real-time data visualization and monitoring dashboard
• InfluxDB: High-performance data storage
• Node-RED: Flow-based development tool for visual programming and data flow automation

Prerequisites

• Docker
• Docker Compose
• Git

Installation

git clone https://github.com/your-repo/iot-backend-prototyping.git
cd iot-backend-prototyping

Launch Docker Containers

bash

docker-compose up -d

Docker

First install DockerDesktop and docker-compose:

• https://www.docker.com/products/docker-desktop/
• https://docs.docker.com/compose/install/

docker-compose --file software/container/docker-compose.yml up

Mosquitto

Eclipse Mosquitto is an open source message broker which implements a server for MQTT. It runs in Docker and is exposed on the default MQTT port 1883. You can subscribe to and push into topics:

mosquitto_sub -h localhost -t '#' -p 1883
mosquitto_pub -h localhost -p 1883 -t '/' -m $(date --utc +%s)

There is also a very usefuly tool to debug MQTT: MQTT Explorer, that is also available at mqtt-explorer.com.

Node-RED

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.

It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click

NodeRed is also running in Docker: http://localhost:1880/

A simple introduction to Node-RED can be found - along with the nodes / the code - in this repository, please have a look!

InfluxDB

InfluxDB is a database for any time series data with a single. It runs in Docker and is exposed on port 8086:

InfluxDb is running here: http://localhost:8086/ (admin:adminadmin)

Grafana

Grafana is a software to build operational dashboards. It runs in Docker and is exposed on port 3000:

You can login to Grafana: http://localhost:3000/login (admin:admin)
