<p>One side effect of using bind mounts, for better or for worse, is that <strong>you can change the host filesystem via processes running in a container,</strong> including creating, modifying, or deleting important system files or directories.

This is a powerful ability which can have security implications, including impacting non-Docker processes on the host system</p>

<p>A tmpfs mount is not persisted on disk, either on the Docker host or within a container.

<p>If you mount an <strong>empty volume</strong> into a directory in the container in which files or directories exist, these files or directories are propagated (copied) into the volume. Similarly, if you start a container and specify a volume which does not already exist, an empty volume is created for you. This is a good way to pre-populate data that another container needs.</p>

<p>If you mount a <strong>bind mount or non-empty volume</strong> into a directory in the container in which some files or directories exist, these files or directories are obscured by the mount, just as if you saved files into /mnt on a Linux host and then mounted a USB drive into /mnt. The contents of /mnt would be obscured by the contents of the USB drive until the USB drive were unmounted. The obscured files are not removed or altered, but are not accessible while the bind mount or volume is mounted.</p>
