Simple HomeAssistant docker-compose setup

First, create a directory where HomeAssistant will reside. I use /opt/homeassistant.

Create docker-compose.yml:

services:
  homeassistant:
    container_name: homeassistant
    restart: unless-stopped
    image: ghcr.io/home-assistant/home-assistant:stable
    network_mode: host
    privileged: true
    environment:
      - TZ=Europe/Berlin
    volumes:
      - ./homeassistant_config:/config
    depends_on:
      - mosquitto
  mosquitto:
    image: eclipse-mosquitto
    network_mode: host
    volumes:
      - ./mosquitto_conf:/mosquitto/config
      - ./mosquitto_data:/mosquitto/data
      - ./mosquitto_log:/mosquitto/log

Now start homeassistant so it creates the default config files:

docker-compose up

Once you see

homeassistant    | [services.d] done.

Press Ctrl+C to abort.

Now we’ll create the Mosquitto MQTT server config file in mosquitto_conf/mosquitto.conf:

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

listener 1883
## Authentication ##
allow_anonymous false
password_file /mosquitto/config/mosquitto.passwd

Now create the mosquitto password file and fix the permissions using

touch mosquitto_conf/mosquitto.passwd
chown -R 1883:1883 mosquitto_conf

We can now start create the homeassistant mosquitto user using

docker-compose run mosquitto mosquitto_passwd -c /mosquitto/config/mosquitto.passwd homeassistant

Enter a random password that will be used for the homeassistant user

Now we can edit the homeassistant config homeassistant_config/configuration.yml. This is my config - ensure to insert the random MQTT password we used before instead of ep2ooy8di3avohn1Ahm6eegheiResh:

# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

http:
  use_x_forwarded_for: true
  trusted_proxies:
  - 127.0.0.1
  ip_ban_enabled: true
  login_attempts_threshold: 5

mqtt:
  broker: "127.0.0.1"
  username: "homeassistant"
  password: "ep2ooy8di3avohn1Ahm6eegheiResh"

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

Now we can start the server using

docker-compose up

You can also use our script to generate a systemd service to autostart the docker-compose config on boot:

curl -fsSL https://techoverflow.net/scripts/create-docker-compose-service.sh | sudo bash /dev/stdin

Now login to the web interface on port 8123 and configure your HomeAssistant!
