Pi-hole behind Traefik-v2-Proxy

[erde815]

Hello everybody,

Currently I am trying to make Pi-hole avaible with the Traefik-v2-Proxy on my network. I looked at some toutorials on the internet and also experimented myself. But unfornunately it does not work.

My docker-compose.yaml for Traefik

version: "3.4"

networks:
  bridge_proxy:
    external: true

services:
  traefik:
    tty: false
    image: traefik:latest
    restart: unless-stopped
    hostname: traefik.nonprod.fritz.box
    container_name: traefik
    dns: 172.31.200.2
    dns_search: nonprod.fritz.box
    extra_hosts:
      - "dev-srv:192.168.0.40"
    ports:
      - "80:80/tcp"
      - "443:443/tcp"
      - "8080:8080/tcp"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    networks:
        bridge_proxy:
          ipv4_address: 172.31.201.1
    command:
      - "--log.level=DEBUG"
      - "--providers.docker.exposedByDefault=false"
      - "--providers.docker.network=bridge_proxy"
      - "--providers.docker.endpoint=unix:///var/run/docker.sock"
      - "--global.checknewversion=false"
      - "--global.sendanonymoususage=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--entrypoints.traefik.address=:8080"
      - "--entrypoints.web.http.redirections.entrypoint.to=websecure"
      - "--entrypoints.web.http.redirections.entrypoint.scheme=https"
      - "--api.insecure=true"
      - "--api.dashboard=true"
      - "--api.debug=true"

My docker-compose.yaml for Pi-hole:

version: "3.4"

networks:
  bridge_proxy:
      external: true

services:
  pihole:
    image: pihole/pihole:latest
    restart: unless-stopped
    hostname: pihole.nonprod.fritz.box
    container_name: pihole
    cap_add:
      - NET_ADMIN
    extra_hosts:
      - "dev-srv:192.168.0.40"
    ports:
      - "53:53/udp"
      - "53:53/tcp"
    volumes:
      - './etc_pihole/:/etc/pihole'
      - './etc_dnsmasq.d/:/etc/dnsmasq.d'
    environment:
      TZ: 'Europe/Berlin'
      WEBPASSWORD: 'foobar'
      DNS1: '192.168.0.1'
      DNS2: '8.8.4.4'
    networks:
      bridge_proxy:
        ipv4_address: 172.31.200.3
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=bridge_proxy"
      # routers configuration
      - "traefik.http.routers.pihole.entrypoints=websecure"
      - "traefik.http.routers.pihole.rule=Host(`dev-srv.fritz.box`)&&Path(`/pihole`)"
      - "traefik.http.routers.pihole.middlewares=addprefix-pihole"
      - "traefik.http.routers.pihole.service=pihole"
      # middlewares configuration
      - "traefik.http.middlewares.addprefix-pihole.addprefix.prefix=/admin"
      # services configuration
      - "traefik.http.services.pihole.loadbalancer.server.port=80"
      - "traefik.http.services.pihole.loadbalancer.passhostheader=true"

I can access Pi-Hole by ip address (172.31.200.3). There I can log in and the website is displayed to me completely. If I open Pi-hole with the Traefik-URL (https://dev-srv.fritz.box/pihole) then I have the error message 404.

Can you help me please? Thanks in advance.

Greetings Erik
