      description:
      - Name of the resource. Provided by the client when the resource is created.
        The name must be 1-63 characters long, and comply with RFC1035. Specifically,
        the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?`
        which means the first character must be a lowercase letter, and all following

      description:
      - Size of the persistent disk, specified in GB. You can specify this field when
        creating a persistent disk using the sourceImage or sourceSnapshot parameter,
        or specify it alone to create an empty persistent disk.
      - If you specify this field along with sourceImage or sourceSnapshot, the value
        of sizeGb must not be less than the size of the sourceImage or the size of
        the snapshot.

    diskEncryptionKey:
      description:
      - Encrypts the disk using a customer-supplied encryption key.
      - After you encrypt a disk with a customer-supplied key, you must provide the
        same key if you use the disk later (e.g. to create a disk snapshot or an image,
        or to attach the disk to a virtual machine).
      - Customer-supplied encryption keys do not protect access to metadata of the
        disk.
      - If you do not provide an encryption key when creating the disk, then the disk
        will be encrypted using an automatically generated key and you do not need
        to provide a key to use the disk later.

          description:

            key that protects this resource.

      - The source snapshot used to create this disk. You can provide this as a partial
        or full URL to the resource.
      returned: success
      type: dict
    sourceSnapshotEncryptionKey:
      description:
      - The customer-supplied encryption key of the source snapshot. Required if the
        source snapshot is protected by a customer-supplied encryption key.

    sourceSnapshotId:
      description:
      - The unique ID of the snapshot used to create this disk. This value identifies
        the exact snapshot that was used to create this persistent disk. For example,
        if you created the persistent disk from a snapshot that was later deleted
        and recreated under the same name, the source snapshot ID would identify the
        exact version of the snapshot that was used.
