What is mosquitto?

from eclipse/mosquitto:

Mosquitto is an open source implementation of a server for version 3.1 and 3.1.1 of the MQTT protocol. It also includes a C and C++ client library, and the mosquitto_pub and mosquitto_sub utilities for publishing and subscribing.

from mqtt.org:

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers.

Usage

How to use this image

This image contains the server binary from the mosquitto project and client utilities such as mosquitto_pub and mosquitto_sub for publishing and subscribing.

❯ docker run --rm -it ruimarinho/mosquitto

By default, the mosquitto server will run as user mosquitto for security reasons and on the default port 1883.

Using a custom config

The default /etc/mosquitto is read by the mosquitto server so you can map a host volume to customize it:

❯ docker run \
  -p 1883:1883 \
  -p 9001:9001 \
  -v /volume1/applications/mosquitto:/etc/mosquitto \
  -d \
  mosquitto -c /etc/mosquitto/mosquitto.conf -v

Running mosquitto client utilities

Run a test server:

❯ docker run --rm -it \
  --name mosquitto-server \
  ruimarinho/mosquitto

mosquitto_sub

mosquitto_sub is an mqtt client that subscribes to a single topic and prints all the messages it receives.

❯ docker run --rm -it \
  --link mosquitto-server \
  ruimarinho/mosquitto mosquitto_sub -h mosquitto-server -t '#'

mosquitto_pub

mosquitto_pub is an mqtt client that publishes a message on a single topic and exits.

❯ docker run --rm -it \
  --link mosquitto-server \
  ruimarinho/mosquitto mosquitto_pub -h mosquitto-server -t home-assistant/switch/1/on -m "Switch is ON"
