#attached_disk_obj(source, writable: true, boot: false, device_name: nil, encryption_key: nil, auto_delete: false) ⇒ Hash

Returns an attached disk configuration hash.

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

Example output: 

:boot=>true,
:mode=>"READ_WRITE",
:source=>"https://www.googleapis.com/compute/v1/projects/myproj/zones/us-central1-f/disks/mydisk",
:type=>"PERSISTENT"

See Instances.insert API docs for more info: cloud.google.com/compute/docs/reference/rest/v1/instances/insert

Parameters:

  • source (String) —

    self_link of an existing disk resource

  • writable (Boolean) (defaults to: true) —

    The mode in which to attach this disk. (defaults to READ_WRITE)

  • boot (Boolean) (defaults to: false) —

    Indicates whether this is a boot disk. (defaults to false)

  • device_name (String) (defaults to: nil) —

    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.

  • encryption_key (Object) (defaults to: nil) —

    Encrypts or decrypts a disk using a customer-supplied encryption key.

  • auto_delete (Object) (defaults to: false) —

    Specifies whether the disk will be auto-deleted when the instance is deleted. (defaults to false)

Returns:

  • (Hash)
