Running Mosquitto with auth in Docker

Simple example of how to run Mosquitto with auth in Docker. Based on the official Eclipse Mosquitto MQTT Broker Docker image.

Place the Mosquitto credentials to the .env file that will be used by the docker-compose.

MOSQUITTO_USERNAME=mosquitto
MOSQUITTO_PASSWORD=mosquitto

Build and run

docker-compose build
docker-compose up -d

Testing

Try the MQTT client to connect to the Mosquitto MQTT Broker. Use 127.0.0.1:1883 for a local environment.

Or use official mosquitto_pub and mosquitto_sub utilities for publishing and subscribing.

# Subscribe to topic.
mosquitto_sub -h localhost -t test -u "mosquitto" -P "mosquitto"

# Publish a message.
mosquitto_pub -h localhost -t test -m "hello." -u "mosquitto" -P "mosquitto"
