MQTT with RabbitMQ and Node-RED

This post shows how to enable MQTT in RabbitMQ, and use Node-RED to test the setup. Official Docker container images of both RabbitMQ and Node-RED are used for convenience.

To start RabbitMQ Docker container run

docker run -it --name myrabbitmq -p 5672:5672 -p 15672:15672 -p 1883:1883 -p 15675:15675 rabbitmq:3

AMQP port 5672, management web interface port 15672, MQTT protocol port 1883, and WebSocket protocol port 15675 are exposed. MQTT over WebSocket can be accessed at ws://

If you kill the above shell and need to run the same container again

docker start -ai myrabbitmq

Management web interface plugin and MQTT plugin need to be enabled next.

Start a Bash shell into the container

docker exec -it myrabbitmq /bin/bash

Enable the plugins by issuing the rabbitmq-plugins command

rabbitmq-plugins enable rabbitmq_management
rabbitmq-plugins enable rabbitmq_mqtt
rabbitmq-plugins enable rabbitmq_web_mqtt
rabbitmq-plugins enable rabbitmq_amqp1_0

Now, you should be able to log into the management interface at http://localhost:15672 using username/password guest/guest, and use MQTT from any compatible MQTT client. AMQP 1.0 plugin is also enabled in case you want to emulate a service such as Azure Service Bus.

Node-RED, a popular tool to orchestrate IoT devices, can now be used to test MQTT.
