How to use Traefik v1.7 with Let's Encrypt and Docker?

Traefik Traefik v1

Hi everyone,

I'm trying to do this official tutoriel for configuring Traefik with Let's Encrypt and Docker: https://docs.traefik.io/v1.7/user-guide/docker-and-lets-encrypt/

Instead of having the my-docker-registry.com/my-awesome-app/app:latest image, I used the containous/whoami image.

However, it seems to me that it is not working. I cannot access the host whoami.shinobi.com either through http or https. I can only access it with the http link and the ip address provided in the backend section of the Traefik dashboard.

Here's the docker-compose.yml file for the Traefik reverse proxy:

version: '3.7'

services:
  traefik:
    image: traefik:v1.7
    restart: always
    ports:
      - 80:80
      - 443:443
      - 8080:8080
    networks:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./acme.json:/acme.json
    container_name: traefik
    command:
      - --api
      - --docker
      - --debug=true
      - --logLevel=DEBUG
      - --defaultentrypoints=https,http
      - --entryPoints=Name:http Address::80 Redirect.EntryPoint:https
      - --entryPoints=Name:https Address::443 TLS
      - --retry
      - --docker.endpoint=unix:///var/run/docker.sock
      - --docker.watch=true
      - --docker.exposedbydefault=false
      - --docker.domain=shinobi.com
      - --acme.email=myemail@address.com
      - --acme.storage=acme.json
      - --acme.entryPoint=https
      - --acme.onHostRule=true
      - --acme.httpchallenge.entrypoint=http
      - --acme.caServer=https://acme-staging-v02.api.letsencrypt.org/directory

    labels:
      - "traefik.enable=true"
      - "traefik:frontend.rule=Host:monitor.traefik.com"

networks:
  web:
    external: true

and here the docker-compose.yml file for the whoami application:

version: '3.7'

services:
  whoami:
    image: containous/whoami
    depends_on:
      - db
      - redis
    restart: always
    networks:
      - web
      - default 
    labels:
      - "traefik.docker.network=web"
      - "traefik.enable=true"
      - "traefik.basic.frontend.rule=Host:whoami.shinobi.com"
      - "traefik.basic.protocol=http"
      - "traefik.admin.frontend.rule=Host:admin.shinobi.com"
      - "traefik.admin.protocol=https"
      - "traefik.admin.port=443"
    
  db:
    image: postgres:12
    restart: always
    
  redis:
    image: redis:latest
    restart: always 
    
networks:
  web:
    external: true

Can someone please provide some guidance?

I have those errors on the Traefik logs:
