Auto delete disk using libcloud

i'm trying to create a VM using libcloud with auto delete feature. The thing is that it only works for boot disks.

Example:

new_node = driver.create_node("my_node_str", size, get_root_snapshot(driver), location,ex_service_accounts=sa_scopes, ex_disk_auto_delete=True, ...

Then I attach a disk:

driver.attach_volume(my_node,...,ex_boot=False, ex_auto_delete=True)

So i go to GCE and this volume auto delete is turned OFF

So, i try to change it "manually" using libcloud:

conn.ex_set_volume_auto_delete(vol, node)

And I get the error :

libcloud.common.google.GoogleBaseError: u"Invalid value for field 'disk': 'myvolume1-worker-disk'

But the disk is created, attached and it is working on my VM.

Debugging libloud everything seems to be ok acording to documentation (https://cloud.google.com/compute/docs/reference/latest/instances/setDiskAutoDelete):

It calls:

u'/zones/us-central1-b/instances/myinstancename/setDiskAutoDelete'

With parameters: 'deviceName': volume.name, 'autoDelete': auto_delete, any clues?

It looks like there may be a bug with attach_volume. I'll do a bit of testing and get that fixed up if so.

Regarding using ex_set_volume_auto_delete, you need to pass in a StorageVolume object. It looks like you are just passing in a string (the name of the disk).

You could try,

disk_obj = driver.ex_get_volume('string-name-of-disk')
driver.ex_set_volume_auto_delete(node_obj, disk_obj, ex_auto_delete=True)

I'll follow up about the first issue when I look into it more.
