Installation Instructions Using Docker Compose

Installing Home Assistant using Docker Compose is a straightforward way to get started. Docker Compose simplifies deployment by managing Home Assistant and its dependencies through a single configuration file.

Prerequisites
  • Ubuntu server (18.04 or later)
  • Docker and Docker Compose installed

Install Docker and Docker Compose:

If Docker and Docker Compose are not already installed, you can install them with the following commands:

# Install Docker
sudo apt update
sudo apt install -y docker.io

# Start and enable Docker service
sudo systemctl start docker
sudo systemctl enable docker

# Install Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Docker Compose Configuration for Home Assistant

  1. Create a Directory for Home Assistant:

    mkdir home-assistant
cd home-assistant

  2. Create a Docker Compose File:

    Create a file named docker-compose.yml in the Home Assistant directory with the following content:

    services:
  homeassistant:
    container_name: home-assistant
    image: "ghcr.io/home-assistant/home-assistant:stable"
    volumes:
      - ${DOCKER}/home-assistant/config:/config
      - /etc/localtime:/etc/localtime:ro
    environment:
      - PUID=${PUID}
      - PGID=${PGID}
      - TZ=${TZ} 
    restart: unless-stopped
    ports:
      - ${HTTP_PORT}:8123
    depends_on:
      - homeassistant-db
    privileged: true

  homeassistant-db:
    image: docker.io/postgres:16.3
    container_name: homeassistant-db
    restart: unless-stopped
    environment:
      - POSTGRES_USER=homeassistant_user
      - POSTGRES_PASSWORD=superstrongpassword
      - POSTGRES_DB=homeassistant-db
      # ensure the database gets created correctly
      # https://github.com/matrix-org/synapse/blob/master/docs/postgres.md#set-up-database
      - POSTGRES_INITDB_ARGS=--encoding=UTF-8
    volumes:
      - ${DOCKER}/home-assistant/schemas:/var/lib/postgresql/data
    security_opt:
      - no-new-privileges:true

    This configuration sets up the Home Assistant container, uses the latest image, and maps the container's configuration directory to a Docker volume for data persistence.

  3. Start the Home Assistant Container:

    Run the following command to start Home Assistant using Docker Compose:

    sudo docker-compose up -d

    This command downloads the Home Assistant Docker image (if not already available), creates and starts the container in detached mode.

  4. Verify the Installation:

    Open your web browser and navigate to http://<your_server_ip>:8123 to access the Home Assistant web interface. You should see the Home Assistant onboarding screen if the installation was successful.

Basic Setup Instructions
