 | **volume-nocopy**     | By default, if you attach an empty volume to a container, and files or directories already existed at the mount-path in the container (`dst`), the Engine copies those files and directories into the volume, allowing the host to access them. Set `volume-nocopy` to disables copying files from the container's filesystem to the volume and mount the empty volume.<br /><br />A value is optional:<ul><li>`true` or `1`: Default if you do not provide a value. Disables copying.</li><li>`false` or `0`: Enables copying.</li></ul>
 | **volume-opt**        | Options specific to a given volume driver, which will be passed to the driver when creating the volume. Options are provided as a comma-separated list of key/value pairs, for example, `volume-opt=some-option=some-value,some-other-option=some-other-value`. For available options for a given driver, refer to that driver's documentation.
