Note

The unix-block device type is supported for containers. It supports hotplugging.

Unix block devices make the specified block device appear as a device in the instance (under /dev). You can read from the device and write to it.

Device options

unix-block devices have the following device options:

Key	Type	Default	Description
gid	int	0	GID of the device owner in the instance
major	int	device on host	Device major number
minor	int	device on host	Device minor number
mode	int	0660	Mode of the device in the instance
path	string	-	Path inside the instance (one of source and path must be set)
required	bool	true	Whether this device is required to start the instance (see Hotplugging)
source	string	-	Path on the host (one of source and path must be set)
uid	int	0	UID of the device owner in the instance

Hotplugging

Hotplugging is enabled if you set required=false and specify the source option for the device.

In this case, the device is automatically passed into the container when it appears on the host, even after the container starts. If the device disappears from the host system, it is removed from the container as well.
