Reverse proxy to remote url

Traefik Traefik v2
,
1

Hi,

I have a main server, exposed to the outside with ports 80 and 443.
I already have a Traefik instance working well with docker.
I now have a RaspberryPi, on my network, that I would like to expose, but through my main reverse-proxy (traefik).

It should look like this.

But I'm not able to generate my backend service.
As if Traefik doesn't care about my configuration.

My docker-compose.yml file:

version: "2"

services:
  traefik:
    image: traefik:latest
    restart: always
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    networks:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./acme.json:/acme.json
      - ./traefik.yaml:/traefik.yaml
    container_name: traefik

  whoamii:
    image: containous/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.rule=Host(`leon.xxxxxx.fr`)"
    networks: 
      - web

networks:
  web:
    external: true
  local:

My traefik.yml :

log: 
  level: DEBUG
api: 
  insecure: true  
entryPoints: 
  web: 
    address: ":80"
  websecure: 
    address: ":443"

  docker: 
    exposedByDefault: false

  letsencrypt:
    acme:

      storage: /acme.json
      tlschallenge: {}
http: 
  routers: 
    homeass:
      entryPoints: 
        - websecure
      service: homeass
      rule: "Host(`domo.xxxxxx.fr`)"
      tls: {}
  services: 
    homeass:
      loadBalancer:
        servers: 
          - "http://192.168.1.202"

When I access to my dashboard, I have no trace of my service.

What did I miss ?
Why can't I generate my service ?

Thanks for the help,

Hi @LeNouveau

You are mixing static and dynamic configuration in your traefik.yml
https://doc.traefik.io/traefik/getting-started/configuration-overview/

Split out your dynamic options into another file and add a parameter to load the dynamic configuration.

Hi,

I never realised there are 2 types of files.

## Dynamic configuration

Now, I understand what it means, in the examples. ^^'

Thanks you !
