title: Docker: Difference between `docker run` and `docker service`
body: <p>I am very new to <code>docker</code> , just started venturing into this. I read online about this. I came to know of the following commands of <code>docker</code> which is: <code>docker run</code> and <code>docker service</code>. As I understood , with <code>docker run</code> we are spinning a new <code>container</code>. However I am not clear what <code>docker service</code> do? Does it spin container in a <code>Swarm</code>?</p>
  
  <p>Can anyone help understand in simple to understand?</p>
