Setup MQTT Server

Docker Environment

In preparation for the MQTT instance, you must have Docker running on your server. I also recommend using Portainer.

Installation

I ran the eclipse-mosquitto:latest image from the Docker Hub with the following settings: - Name: mosquitto - Restart Policy: unless-stopped - Network: bridge - Ports: 1883:1883 - Volumes: /opt/mosquitto/config:/mosquitto/config and /opt/mosquitto/data:/mosquitto/data and /opt/mosquitto/log:/mosquitto/log - Environment Variables: TZ=Europe/Berlin You can change this to your timezone

Configuration

Config File

In the container under /mosquitto/config you will find the mosquitto.conf file. I changed the following settings to activate the password file and to disable anonymous access (1) :

  1. This must be executed in the container!
Bash
1
2
3
# Require authentication
allow_anonymous false
password_file /mosquitto/config/mqttuser

Add User

To add a user to the MQTT server, you can use the following commands:

First User

Bash
1
mosquitto_passwd -c /mosquitto/config/mqttuser [username]

Additional Users

Bash
1
mosquitto_passwd /mosquitto/config/mqttuser [username]
