title: Docker Container run -d flag
body: <p>I am running docker run container command in 2 ways</p>
  
  <ol>
  <li><code>docker container run 4e5021d210f6</code>
  
  <ul>
  <li>It shows container exited N seconds ago on running docker container ls -a</li>
  </ul></li>
  <li><code>docker container run -d 4e5021d210f6</code> 
  
  <ul>
  <li>It also shows container exited N seconds ago on running docker container ls -a 
  but do get some long string "954f102a3c83f6fb7c83189415448c4bb101ff1afe775f2d9b7b4cd70f4e137e" (I do not know what is this number)</li>
  </ul></li>
  </ol>
