title: How can I run docker container without entering into container
body: <p>I have Dockefile</p>
  
  <pre><code>FROM centos:7
  </code></pre>
  
  <p>So I have no entrypoint in dockerfile.
  Then I build it to image </p>
  
  <pre><code>sudo docker build -t my_container .
  </code></pre>
  
  <p>Then I start it.</p>
  
  <pre><code>sudo docker run -t my_container
  </code></pre>
  
  <p>And I get open tty to container    </p>
  
  <pre><code>root@my_container_id/
  </code></pre>
  
  <p>If I start it without <code>-t</code> it stopped immidiately after start.
  How can I run docker container without start tty and without entrypoint?</p>
