Mainflux

Mainflux is modern, scalable, secure, open-source, and patent-free IoT cloud platform written in Go.

It accepts user and thing (sensor, actuator, application) connections over various network protocols (i.e. HTTP, MQTT, WebSocket, CoAP), thus making a seamless bridge between them. It is used as the IoT middleware for building complex IoT solutions.

For more details, check out the official documentation.

Features

• Multi-protocol connectivity and bridging (HTTP, MQTT, WebSocket and CoAP)
• Device management and provisioning (Zero Touch provisioning)
• Mutual TLS Authentication (mTLS) using X.509 Certificates
• Fine-grained access control (policies, ABAC/RBAC)
• Message persistence (Cassandra, InfluxDB, MongoDB and PostgresSQL)
• Platform logging and instrumentation support (Prometheus and OpenTelemetry)
• Event sourcing
• Container-based deployment using Docker and Kubernetes
• LoRaWAN network integration
• OPC UA integration
• Edge Agent and Export services for remote IoT gateway management and edge computing
• SDK
• CLI
• Small memory footprint and fast execution
• Domain-driven design architecture, high-quality code and test coverage

Prerequisites

The following are needed to run Mainflux:

• Docker (version 20.10)
• Docker compose (version 1.29)

Developing Mainflux will also require:

• Go (version 1.19.2)
• Protobuf (version 3.6.1)

Install

Once the prerequisites are installed, execute the following commands from the project's root:

docker-compose -f docker/docker-compose.yml up

This will bring up the Mainflux docker services and interconnect them. This command can also be executed using the project's included Makefile:

make run

If you want to run services from specific release checkout code from github and make sure that MF_RELEASE_TAG in .env is being set to match the release version

git checkout tags/<release_number> -b <release_number>
# e.g. `git checkout tags/0.13.0 -b 0.13.0`

Check that .env file contains:

MF_RELEASE_TAG=<release_number>

docker-compose should be used for development and testing deployments. For production we suggest using Kubernetes.

Usage

The quickest way to start using Mainflux is via the CLI. The latest version can be downloaded from the official releases page.

It can also be built and used from the project's root directory:

make cli
./build/mainflux-cli version

Additional details on using the CLI can be found in the CLI documentation.
