--ipc=how

Sets the configuration for IPC namespaces when handling RUN instructions. The configured value can be "" (the empty string) or "container" to indicate that a new IPC namespace is created, or it can be "host" to indicate that the IPC namespace in which podman itself is being run is reused, or it can be the path to an IPC namespace which is already in use by another process.
