title: Is it possible to share memory between docker containers?
body: <p>I work on an application with different processes and I'm asked to contain those processes for achieving more isolation.</p>
  
  <p>The problem is that the processes share memory with a single "hypervisor" process in order to exchange data (they use classic shared buffers). This solution was implemented for performance requirement and because it is running in user-space, so there aren't content switching between user-space and kernel-space.</p>
  
  <p>If I'm not wrong is not possible to run more than one docker container inside a single IPC namespace, but I don't know if it is possible that a single docker container belongs to different IPC namespaces, this could solve my problem. </p>
  
  <p>Other solutions are welcome, just keep in mind that performance is a requirement, thanks in advance.</p>
