title: Docker contain receiving unsolicited HTTP POST Requests
body: <p>When i start my django app in a docker container. I get the following Error/Warning every 5 or 10 seconds. (the app is using gunicorn HTTP server)</p>
  
  <blockquote>
    <p>Invalid HTTP_HOST header: '10.255.255.12:8082'. You may need to add
    u'10.255.255.12' to ALLOWED_HOSTS.</p>
  </blockquote>
  
  <p>My question is not how to fix the error, but what is making the requests? I realise that this may be as a result of some line of code in my app, and i haven't shared any of my code. I am asking if anyone is aware of anything with django/gunicorn/docker which would be sending requests, perhaps some sort of tool which makes requests periodically as a status test?</p>
