Reference documentation and code samples for the Batch v1alpha API class AllocationPolicy.Types.AttachedDisk.
A new or an existing persistent disk (PD) or a local ssd attached to a VM
instance.
Device name that the guest operating system will see.
It is used by Runnable.volumes field to mount disks. So please specify
the device_name if you want Batch to help mount the disk, and it should
match the device_name field in volumes.
