Answer
IPC namespaces isolate shared memory and semaphore segments.
Quick Answer
Docker uses IPC namespaces to isolate System V IPC (message queues, semaphores, shared memory) between containers. By default each container gets its own IPC namespace — processes in different containers can't share memory or signal each other via IPC. --ipc=host or --ipc=container: relaxes this for specific use cases.
