title: Docker "Sharing Dependencies"
body: <p>Along with the readings with Docker, I stopped a couple of times with the fact that Docker containers not only share the host kernel, but If possible they share common binaries and libraries.</p>
  
  <p>What I understand from that, is that If I'm running the same docker Image twice on the same host, and this image is using some files x,y,z  (say libraries / bins .. anything). These files will also be shared among the 2 launched containers? What is even more is that if I'm running two different images, they still could share these common dependencies. What I'm asking for is just two things ... </p>
  
  <p>1- Verification / Explanation --> Is that true / false + explanation (how does that happen)<br>
  2- If true --> Is there a practical example, that I can run 2 containers (of the same / diff images) and verify they are seeing the same files / libs. </p>
  
  <p>I hope my question is clear and someone has an answer :) </p>
