A prerequisite for doing this is that the hosts have joined the same Swarm.\n\nTo join an overlay network named multi-host-network with a busybox container\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker run --network multi-host-network busybox sh\n```\n\n> [!NOTE] > > This only works if the overlay network is attachable > (created with the --attachable flag).\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
