title: Is there a formula for calculating the overhead of a Docker container?
body: <p>Supposed I want to run several Docker containers at the same time.</p>
  
  <p>Is there any formula I can use to find out in advance on how many containers can be run at the same time by a single Docker host? I.e., how much CPU, memory &amp; co. do I have to take into account for the containers themselves?</p>
