Open Stack

Hi All,


After deleting the heat-stack , I am polling until the stack is DELETED.

I am following below way of polling until stack-get fails with HTTPNotFound
Exception.

Is there any other better way of checking whether stack is DELETED instead
of catching exception.

>>> from heatclient.client import Client

heat_client = Client('1', endpoint=heat_url, token=auth_token)

heat_client.stacks.delete(stack_name)


******poll loop**********

try:

    stack_get = heat_client.stacks.get(stack_name)

except (heatexception.HTTPNotFound):

                # stack is deleted

if 'IN_PROGRESS' in stack_get.status:

               # sleep and again loop

*********************************


Thanks

Eswar
