Home Assistant Docker Setup with Traefik

This guide provides instructions for deploying Home Assistant using Docker and Traefik as a reverse proxy. The setup includes securing the Home Assistant instance with HTTPS and configuring a trusted proxy.

Prerequisites

Docker and Docker Compose installed on your system
Traefik configured as your reverse proxy
A domain name pointing to your Home Assistant instance

Environment Variables

Before deploying the container, create a .env file from the provided .env-example file and adjust the values as needed.

cp .env-example .env
nano .env

`.env-example` file

# Home Assistant Version (Default: latest)
HOMEASSISTANT_VERSION=latest

# Home Assistant Domain
HOMEASSISTANT_DOMAIN=homeassistant.example.com

Starting the Container

Once the .env file is configured, start the Home Assistant container using:

docker-compose up -d

Configuring the Reverse Proxy

To enable proper proxy support in Home Assistant, update data/config/configuration.yaml with the following settings:

Finding the Local Subnet IP

To determine the Docker subnet used by Home Assistant, run:

docker inspect homeassistant | grep Gateway

`configuration.yaml`

http:
  ip_ban_enabled: true
  login_attempts_threshold: 5
  use_x_forwarded_for: true
  trusted_proxies:
    - 10.0.0.0/24 # Local Subnet
    - 172.18.0.0/24 # Your Docker Subnet

Accessing Home Assistant

Once everything is set up, restart Home Assistant and it should be accessible via the configured domain:

https://homeassistant.example.com

If there are any issues, check the container logs with:

docker logs -f homeassistant
