title: How Should I Get Application Configuration into my Docker Containers?
body: <p>I read the following article about "How Should I Get Application Configuration into my Docker Containers?"
  <a href="https://dantehranian.wordpress.com/2015/03/25/how-should-i-get-application-configuration-into-my-docker-containers/" rel="noreferrer">https://dantehranian.wordpress.com/2015/03/25/how-should-i-get-application-configuration-into-my-docker-containers/</a></p>
  
  <p>It summarizes 4 options for this that were relevant back in 2015.
  In short:</p>
  
  <ol>
  <li><p>Baking the Configuration into the Container</p></li>
  <li><p>Setting the Application Configuration Dynamically via Environment Variables</p></li>
  <li><p>Setting the Application Configuration Dynamically via Environment Variables (using an external kv store)</p></li>
  <li><p>Map the Config Files in Directly via Docker Volumes</p></li>
  </ol>
  
  <p>I'm wondering if nowadays these options are still the only ones viable or are there any new options/patterns to do this?</p>
  
  <p>Thanks.</p>
