Please note the following about this traefik example for Docker Pi-hole

  • Still requires standard Pi-hole setup steps, make sure you've gone through the README and understand how to setup Pi-hole without traefik first
  • Update these things before using:
    • set instances of homedomain.lan below to your home domain (typically set in your router)
    • set your Pi-hole ENV WEBPASSWORD if you don't want a random admin pass
  • This works for me, Your mileage may vary!
  • For support, do your best to figure out traefik issues on your own:
    • by looking at logs and traefik web interface on port 8080
    • also by searching the web and searching their forums/docker issues for similar question/problems
  • Port 8053 is mapped directly to Pi-hole to serve as a back door without going through traefik
  • There is some delay after starting your container before traefik forwards the HTTP traffic correctly, give it a minute

After running docker-compose up -d you should see this if you look at logs on traefik docker-compose logs -f traefik

Also your port 8080 should list the Route/Rule for pihole and backend-pihole container.
