sudo mkdir /opt/homeassistant3. Change to the newly created "homeassistant" directory:
cd /opt/homeassistant4. Within the "homeassistant" directory, create a new subdirectory called "config." This subdirectory will store your Home Assistant configuration files:
mkdir configCreating the Docker Compose File
Now that we have the directory structure set up, we'll create the Docker Compose file, which defines the configuration of our Home Assistant container. Open a text editor (nano, vim, or any other of your choice) and create a new file called "docker-compose.yml." Add the following content to the file:
version: '3'
services:
homeassistant:
container_name: homeassistant
image: "ghcr.io/home-assistant/home-assistant:stable"
volumes:
- /opt/homeassistant/config:/config
- /etc/localtime:/etc/localtime:ro
restart: unless-stopped
privileged: true
network_mode: hostSave the file once you've added the above lines. This Docker Compose file defines the configuration for the Home Assistant container, including the image to use (stable version from Docker Hub), volume mappings for the configuration files, container restart behavior, and network mode.
Bringing Up the Container
With the Docker Compose file ready, you can now bring up the Home Assistant container. Follow these steps:
1. Open a terminal and navigate to the /opt/homeassistant directory.
2. Issue the following command to bring up the container:
sudo docker compose up -dLet's break down the command:
sudo: Run the command with root privileges.docker compose: Use Docker Compose to manage the container.up: Bring up the new container as specified in the Compose file.-d: Detach the process, allowing it to run in the background.
The first time you execute this command, Docker Compose will pull the Home Assistant container from Docker Hub.
