Mosquitto MQTT Broker

Frigate with Home Assistant requires an MQTT broker. Here is how to set it up

compose.yml

version: '3.0'

services: 
 mosquitto:
    image: eclipse-mosquitto
    container_name: mosquitto
    volumes:
      - ./:/mosquitto
      - ./data:/mosquitto/data
      - ./log:/mosquitto/log
    ports:
      - 1883:1883
      - 9001:9001 

/mosquitto/config/mosquitto.conf

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
listener 1883

## Authentication ##
allow_anonymous true

setup mosquitto authentication

add a username password so only allowed devices can access this broker

mosquitto_passwd -c /mosquitto/config/password.txt hass

# set new password

/mosquitto/config/mosquitto.conf

update this file to lock down the broker

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
listener 1883

## Authentication ##
allow_anonymous false
password_file /mosquitto/config/password.txt

There will be a permission's issue, resolve this by changing ownership of all files in that folder

sudo chown USER -R /mosquitto
