Is there a command on 20.04 that prints out current disk into like cloud-init wants it

[Jerry Geis]

Is there a command on 20.04 that prints out the cloud-init information for
the disk ?

Like this:
  storage:
    config:
    - {ptable: msdos, wipe: superblock-recursive, preserve: false, name:
'', grub_device: true, type: disk, id: disk-0, match: {size: largest}}
    - {device: disk-0, size: -1,   wipe: superblock, flag: '', number: 1,
preserve: false, grub_device: false, type: partition, id: partition-1}
    - {fstype: ext4, volume: partition-1, preserve: false, type: format,
id: format-1}
    - {device: format-1, path: /,     type: mount, id: mount-1}

Type of output ?
I desire to print the current disk /dev/sda as like above ?
How/where is that done ?

Thanks

Jerry
