Source: https://docs.traefik.io/assets/img/providers.png

Introduction

In this tutorial we will show you how you can route non-Docker services through Traefik.

Let’s suppose you want to access your Pi-hole admin console (http://192.168.0.10:80/admin) by browsing to pihole.example.com.

Prerequisites

You have read our other articles:

• Traefik 2.0 + Docker — a Simple Step by Step Guide
• Traefik 2.0 + Docker — an Advanced Guide

and you use this Traefik configuration.

Make sure you configure in the providers section of your /opt/traefik/data/traefik.yml an external configuration file /config.yml.

providers:                         
  docker:
  endpoint: "unix:///var/run/docker.sock"
  exposedByDefault: false
  file:
    filename: /config.yml

Setup config.yml

Edit /opt/containers/traefik/data/config.yml and create a new router pihole:

http:
  routers:
    pihole:
      entryPoints:
        - "https"
      rule: "Host(`pihole.example.com`)"
      middlewares:
        - addprefix-pihole
      tls:
        certResolver: http
      service: pihole
