title: How to create a docker base image?
body: <p>My local system is ubuntu 14.04. In this local system, I installed VM which contains sles 12. In this local VM (sles 12), I configure some of the application of my use. </p>
  
  <p>I'm totally new to Docker. I want to create a docker base image which contains this sles 12 image into which my applications are also present. </p>
  
  <p>How I can create such a docker image, in which sles 12 os is available and into that my applications also can be run?</p>
