I'm trying to setup Taefik using `docker-compose`.

I tried a lot of things, but still it seems that my Letsencrypt config is mostly ignored. Can somebody help me with fixing my configuration or finding a way to debug this?

**Traefik Config**

`docker-compose.yml`

```auto
version: '3'

services:
  traefik:
    # The official v2 Traefik docker image
    image: traefik:v2.1
    container_name: traefik
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      # So that Traefik can listen to the Docker events
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik.yml:/etc/traefik/traefik.yml
      - ./acme.json:/acme.json

networks:
  default:
    external: 
      name: gateway
# Requires command:
# docker network create \
# --driver=bridge \
# --attachable \
# --internal=false \
# gateway

```

`traefik.yml`

```auto
entrypoints:
  http:
    address: ":80"
  https:
    address: ":443"

providers:
  docker:
    exposedbydefault: false

certificatesresolvers:
  letsencrypt:
    acme:
      email: "js@example.com"
      storage: "/acme.json"
      httpchallenge:
        entrypoint: http
      caServer: "https://acme-staging-v02.api.letsencrypt.org/directory"

api:
  insecure: true 

log:
  level: "DEBUG"
accessLog: {}

```

```auto

-rw-r--r-- 1 root root 583 Mar 21 21:37 docker-compose.yml
-rw------- 1 root root 434 Mar 21 21:28 traefik.yml

```

**Application Config**

```auto
version: '3'

services:
  whoami:
    # A container that exposes an API to show its IP address
    image: containous/whoami
    container_name: whoami
    labels:

      - traefik.http.routers.whoami.tls=true
      - treafik.http.routers.whoami.tls.certresolver=letsencrypt

networks:
  default:
    external: 
      name: gateway

```

Oh no, I got it. It was a typo; I had typed `treafik` instead of `traefik` in the application config... 🙄
