title: docker-compose - restart policy - don't preserve changes in image
body: <p>Let's consider following example:   </p>
  
  <pre><code>version: '3'
  services:
    some_service:
      build: .
      restart: unless-stopped
  </code></pre>
  
  <p>This <code>docker-compose</code> works properly, however during restart it preserve changes (in filesystem) introduced in previous running (before restart).<br>
  How to configure restart-policy to force loosing changes in fileysystem?  Is it possible to change restart-policy on running container?</p>
