Can not reproduce Traefik quick start. Getting http 503 error

[Twofyw]

I'm following Traefik quick start and arrived at the following docker compose file:

version: '3'

services:
  traefik:
    image: traefik:v2.10
    restart: always
    command: --api.insecure=true --providers.docker
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  whoami:
    image: traefik/whoami
    labels:
      - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"

However it always give me http 503 error.

$ curl -v -H Host:whoami.docker.localhost http://127.0.0.1
*   Trying 127.0.0.1:80...
* Connected to 127.0.0.1 (127.0.0.1) port 80 (#0)
> GET / HTTP/1.1

* Connection #0 to host 127.0.0.1 left intact

I've tried to replace the service with python -m http.server using static config and it works. So I wonder if the 503 error is related to the whoami image.

Hello,

As you can see everything works well:

docker-compose.yml

```yml version: '3' services: traefik: image: traefik:v2.10 restart: always command: --api.insecure=true --providers.docker ports: - "80:80" - "443:443" - "8080:8080" volumes: - /var/run/docker.sock:/var/run/docker.sock whoami: image: traefik/whoami:v1.9.0 labels: - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)" ```

Your problem is not related to whoami.
