Hello

I am trying to use the dynamic inventory script:

$ ./openstack.py --host 10.2.1.111

Traceback (most recent call last):

File “./openstack.py”, line 246, in

main()

File “./openstack.py”, line 232, in main

inventory = shade.inventory.OpenStackInventory(\*\*inventory\_args)

File “/usr/local/lib/python2.7/dist-packages/shade/inventory.py”, line 35, in **init**

self.extra\_config = config.get\_extra\_config(

AttributeError: ‘OpenStackConfig’ object has no attribute ‘get\_extra\_config’

That line:

class OpenStackInventory(object):

# Put this here so the capability can be detected with hasattr on the class

extra\_config = None

config = os\_client\_config.config.OpenStackConfig(

config\_files=os\_client\_config.config.CONFIG\_FILES + config\_files)

#Line 35

self.extra\_config = config.get\_extra\_config(

config\_key, config\_defaults)

It is calling os\_client\_config.config.OpenStackConfig

This object has this method get\_extra\_config:

def get\_extra\_config(self, key, defaults=None):

“”"Fetch an arbitrary extra chunk of config, laying in defaults.

:param string key: name of the config section to fetch

:param dict defaults: (optional) default values to merge under the

found config

“”"

if not defaults:

defaults = {}

return \_merge\_clouds(

self.\_normalize\_keys(defaults),

self.\_normalize\_keys(self.cloud\_config.get(key, {})))

Any clue?

Regards

Sergio
