title: Not able to find the magento2 database config file
body: <p>I have setup magento2 in docker container build using the docker file. Now I want to automate the database setup process so looking for the config file where I can set the database configuration like database name,username and password. </p>
  
  <p>Reading few blog post says it is available at <code>/app/etc/env.php</code> but I cannot find the <strong>env.php</strong> file inside these location under my magento2 setup directory.</p>
  
  <p>Those who are docker container for magento2, how do you automate the magento setup process (<strong><em>setting up database &amp; Creating admin account</em></strong>) after magento2 installation.</p>
  
  <p>Why is the env.php missing or does it comes only after initial database  set up is done once. </p>
