--ipc=ipc

Set the IPC namespace mode for a container. The default is to create a private IPC namespace.

• "": Use Podman's default, defined in containers.conf.
• container:id: reuses another container's shared memory, semaphores, and message queues
• host: use the host's shared memory, semaphores, and message queues inside the container. Note: the host mode gives the container full access to local shared memory and is therefore considered insecure.
• none: private IPC namespace, with /dev/shm not mounted.
• ns:path: path to an IPC namespace to join.
• private: private IPC namespace.
• shareable: private IPC namespace with a possibility to share it with other containers.
