title: How to show all shared memory allocated by docker
body: <p>When I run a docker image with <code>ipc=host</code> and call <code>shmget</code> to allocate a shared memory in container, I can run <code>ipcs -m</code> to display this shared memory information on the host.</p>
  
  <p>If I use the default ipc mode to run the docker image, I can run <code>ipcs -m</code> to display shared memory in docker, but I can not use the same method to display it on the host. </p>
  
  <p>Is there any way to display all shared memory information allocated by docker container on the host，even if the ipc mode is not host？</p>
