# Compute API needs attached disks to be specified in a custom format.
# This provides a handy shortcut for generating a preformatted config.

# @param [String] source self_link of an existing disk resource
# @param [Boolean] writable The mode in which to attach this disk.
# (defaults to READ_WRITE)
# @param [Boolean] boot Indicates whether this is a boot disk.
# (defaults to false)
# @param [String] device_name Specifies a unique device name of your
# choice that is reflected into the /dev/disk/by-id/google-* tree of
# a Linux operating system running within the instance.
# @param [Object] encryption_key Encrypts or decrypts a disk using
# a customer-supplied encryption key.
# @param [Object] auto_delete Specifies whether the disk will be
# auto-deleted when the instance is deleted. (defaults to false)
# @return [Hash]
