title: Let a container use the OpenJDK and libraries of an existing container
body: <p>I am doing some experiments with my thesis involving the cold start problem that occurs with containers. My test application is a spring boot application that is build on the openjdk image. The first thing I want to try to resolve the problem of cold start, is the following:</p>
  
  <p>Have a container ready, in the container is the openjdk and the libraries that the springboot app uses. I start my other container, using the ipc and networknamespace of the already existing container, and then be able to use the openjdk and the libraries of this container to run the jar file. </p>
  
  <p>I am not exactly sure on how to achieve this? Can i achieve this by using volumes or should i be looking for a completely different approach?</p>
  
  <p>On a another note, if i want x containers to run, i will make sure there are x pre-existing containers running. This is to make sure that every container has its own specific librarycontainer to work with. Would this be okay ?</p>
  
  <p>In short, any way that I can speed up the spring boot application by using a second containers that is connected through ipc/net; would be helpfull to my problem.</p>
