Catch all domains

I am not able to run a Container within Docker Compose that catches all domains. I tried with

...
environment:
      - VIRTUAL_HOST=_
...

or

...
environment:
      - VIRTUAL_HOST=*
...

or removing VIRTUAL_HOST param

But nothing of above catches the domain, instead throws error 503 Service Temporarily Unavailable.

Any idea?

@wader thank you! works like this:

version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
    environment:
      - DEFAULT_HOST=_
  professional-site:
    image: betalab/professional-site
    container_name: professional-site
    environment:
      - VIRTUAL_HOST=_

I had the same issue, the DEFAULT_HOST behaviour isn’t well documented. I fixed that in pull request #1145
