Eclipse Mosquitto MQTT Broker | Support by cloudimg

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview Eclipse Mosquitto is the open source message broker that implements the MQTT protocol, the de facto standard for lightweight publish and subscribe messaging on the Internet of Things. It is small, fast and battle tested, and is the broker recommended by the OASIS MQTT technical committee. This image delivers Eclipse Mosquitto fully installed and configured, so a working MQTT broker is running within minutes of launch. The current stable line is provided.

What Is Included Eclipse Mosquitto, installed from the official Mosquitto PPA, running as a single node broker. The mosquitto-clients package provides the mosquitto_pub and mosquitto_sub command line tools for publishing and subscribing from the instance itself or remote machines. The broker is the only workload on the image, so the platform stays lean and predictable.

Authentication Enabled By Default The image ships with password authentication switched on. The Mosquitto configuration sets allow_anonymous to false and points at a password file, so anonymous MQTT connections are rejected from the moment the broker starts. There is no public or default broker access.

Secure First Boot On the first boot of your instance a one shot service generates a fresh, strong password for the cloudimg MQTT user, unique to that instance, applies it to the broker with mosquitto_passwd and writes it to a file that only the root user can read. No shared or default MQTT credentials ship in the image.

Ready To Use The broker, the password file and the MQTT command line tools are all configured. Connect over SSH, read the generated password, and immediately publish and subscribe with mosquitto_pub and mosquitto_sub. The broker listens for MQTT on port 1883 by default; the user guide explains how to add a TLS listener on 8883 with your own certificate.
