This places the database files in a known location on the host system, and makes it easy for tools and applications on the host system to access the files. The downside is that the user needs to make sure that the directory exists, and that e.g. directory permissions and other security mechanisms on the host system are set up correctly. | |||

| **WARNING**: because MongoDB uses memory mapped files it is not possible to use it through vboxsf to your host ([vbox bug](https://www.virtualbox.org/ticket/819)). VirtualBox shared folders is not supported by mongodb (see [docs.mongodb.org](https://docs.mongodb.org/manual/administration/production-notes/#fsync-on-directories) and related [jira.mongodb.org](https://jira.mongodb.org/browse/SERVER-8600) bug). This means that it is not possible with the default setup using Docker Toolbox to run a MongoDB container with the data directory mapped to the host. | |||
