Struggling with Ansible GCE inventory

[Tzach Livyatan]

I'm following the instructions at http://docs.ansible.com/ansible/guide_gce.html but failed to get gce.py running

./inventories/gce/gce.py --list

Traceback (most recent call last):

  File "./inventories/gce/gce.py", line 374, in <module>

    GceInventory()

  File "./inventories/gce/gce.py", line 115, in __init__

    self.driver = self.get_gce_driver()

  File "./inventories/gce/gce.py", line 230, in get_gce_driver

    gce = get_driver(Provider.GCE)(*args, **kwargs)

  File "/usr/lib/python2.7/site-packages/libcloud/common/google.py", line 493, in __init__

    "file: '%s'" % key)

ValueError: Missing (or not readable) key file: ''

I set the following env vars:

export GCE_EMAIL=my GCE client email

export GCE_PROJECT=my project

export GCE_CREDENTIALS_FILE_PATH=path to json file

the following works fine:

gcloud compute instances list

so the problem is not with my connectivity or permissions.

Any idea will be appreciated
