Traefik + homeassistant (without TLS certificate)

Traefik Traefik v2
1

Hello!
I've been trying for a few days to make traefik work with homeassistant, but I can't.
I don't know if the problem is with traefik or homeassistant, so I'll start with making sure traefik is set up correctly.

Here's my setup: home wifi (no tls/https required), with a raspberry pi 4 (reserved ip 192.168.2.95) running ubuntu 20.04 and docker. I would like to access my containers via 192.168.2.95/servicename on any browser connected to the home wifi network. So I think traefik is the right tool.

I created an internal network with docker network create pi and I have a single docker-compose file for traefik and homeassistant (which I will populate with other services in the future).

I have found tons of examples of traefik.toml and docker-compose.yml files with traefik and other services, but none has helped. Here is my current configuration:

traefik.toml:

[entryPoints]
  [entryPoints.web]
    address = ":80"

[api]
  dashboard = true
  insecure = true

[providers.docker]
  watch = true
  network = "web" # should this be "pi"?
  exposedByDefault = false

docker-compose.yml:


version: '3.4'
services:
  traefik:
    image: 'traefik:2.3'
    container_name: 'traefik'
    restart: 'unless-stopped'
    ports:
      - '80:80'
      - '8080:8080'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /home/ubuntu/traefik/traefik.toml:/etc/traefik/traefik.toml
    networks:
      - pi

  homeassistant:
    container_name: homeassistant
    image: homeassistant/raspberrypi4-homeassistant:stable
    volumes:
      - /home/ubuntu/homeassistant/config:/config
      - /etc/localtime:/etc/localtime:ro
    restart: unless-stopped
    labels: # do I need a Host rule? do I need middleware to edit the request?
      - 'traefik.enable=true'
      - 'traefik.http.routers.homeassistant.rule=PathPrefix(`/homeassistant`)'
      - 'traefik.http.services.homeassistant.loadbalancer.server.port=8123'
    networks:
      - pi

networks:
  pi:
    external: true

When I navigate to 192.168.2.95/homeassistant the browser gives me a 404: Not Found error. I can access the traefik dashboard at 192.168.2.95:8080, but that's about it. What am I missing?
