title: What causes "Authentication is needed to run '/bin/dd' as the super user" prompt when modifying files created via docker shell?

  <p>I am running a website (built with Laravel) in a Docker container. From within the docker bash shell, I ran some artisan commands (e.g. php artisan make:migration create_users_table). I am guessing the files created by these commands are owned by some Docker user group.</p>
  
  <p>When I try to modify and then save these files (in my IDE, probably as a different user from the Docker user), I get the authentication prompt above. Why is this happening, and what could /bin/dd have to do with this? (I read that dd is a Unix command line utility for converting/copying files, which could have something to do with this).</p>
