Running Home Assistant with Docker (docker-compose)

Home Assistant on Docker is easier than running it with HASSIO IMO. :rocket:

Here is a high-altitude overview of how I run Home Assistant -and- then I’ll dig into the details of my setup.

• Setup Raspbian with Docker and Docker-Compose
• Plugin my Aeon Z-wave script; make sure it’s on /dev/ttyACM0
• Setup scripts for Docker-Compose
• Setup scripts so it runs on startup
• Create a backup process

Okay, details… here is how I run Home Assistant on Docker on a Raspberry Pi 4.

• Install Raspbian on the Raspberry Pi 4.
• Install Docker and Docker-Compose.
• Create /root/docker-compose.yml consisting of the following (NOTE: I use the Aeon z-wave stick at /dev/ttyACM0):

version: '3.7'
services:
  homeassistant:
    container_name: homeassistant
    image: homeassistant/raspberrypi4-homeassistant:latest
    network_mode: "host"
    ports:
      - "8123:8123"
    volumes:
      - /opt/homeassistant:/config
      - /etc/localtime:/etc/localtime:ro
      - /etc/letsencrypt:/etc/letsencrypt:ro
    devices:
      - /dev/ttyACM0:/dev/ttyACM0:rwm
    restart: always
    healthcheck:
      test: ["CMD", "curl", "-f", "http://127.0.0.1:8123"]
      interval: 30s
      timeout: 10s
      retries: 6

• Create the following file for automating the service on startup /etc/systemd/system/home-assistant.service

# /etc/systemd/system/home-assistant.service
