Hello,

I think it's because you are not using the right version, I recommend using an explicit version because the management of the latest tag (no tag means latest) by Docker can be surprising.

version: '3.7'

services:
  fake-service:
    image: traefik/whoami:v1.7.1
    environment:
      - 'WHOAMI_PORT_NUMBER=3993'

$ docker-compose up
issue-traefik-fake-service-1  | 2022/01/08 14:00:18 Starting up on port 3993

v1.10.2 and it still does not work:

When using the env variable instead of the --port command it is ignored completley.

Changing the tag from empty to the given version does not change the behaviour.

@DDzwiedziu I can confirm it is working with traefik/whoami:v1.10.2 docker image.
