title: Declare Name/Variable with Docker Compose
body: <p>Currently I am experimenting with Docker Compose but I want to declare a variable or something and some parts of my code and my folder name get changed when I run <code>docker-compose run ...</code></p>
  <p>Is that even possible with Docker?</p>
  <p>I want to generate a Django-Template and change some parts in the &quot;INSTALLED_APPS&quot; section.</p>
  <p>I cannot find something in the web or on stackoverflow.</p>
  <p>Thank you!</p>
