title: How to install the same version of a docker image?
body: <p>On machine A I have docker image FOO/BAR installed. How do I query the version of that image, and how do I install the same version to machine B?</p>
  
  <p>Please note that on machine B I don't need the newest available version of FOO/BAR, but the same version as machine A. I don't want to keep local modifications to the image made on machine A.</p>
