Docker mounts the path into the container. The file system path must exist before the swarm initializes the container for the task.\n\nThe following examples show bind mount syntax\n\nTo mount a read-write bind\n\nBounded code example (external data; do not execute automatically):\n```console\n  $ docker service create \\\n    --mount type=bind,src=<HOST-PATH>,dst=<CONTAINER-PATH> \\\n    --name myservice \\\n    <IMAGE>\n```\n\nTo mount a read-only bind\n\nBounded code example (external data; do not execute automatically):\n```console\n  $ docker service create \\\n    --mount type=bind,src=<HOST-PATH>,dst=<CONTAINER-PATH>,readonly \\\n    --name myservice \\\n    <IMAGE>\n```\n\n> [!IMPORTANT] > > Bind mounts can be useful but they can also cause problems.
