IndexError: list index out of range for GCE dynamic inventory

[abdulrahim umar]

When running the dynamic inventory script against a gce deployment , some nodes with external ips some without (running connecting through NAT ) i encounter this error when running list:

sh-3.2# ./inventory/gce/gce.py --list

Traceback (most recent call last):

  File "./inventory/gce/gce.py", line 287, in <module>

    GceInventory()

  File "./inventory/gce/gce.py", line 111, in __init__

    print(self.json_format_dict(self.group_instances(),

  File "./inventory/gce/gce.py", line 242, in group_instances

    meta["hostvars"][name] = self.node_to_dict(node)

  File "./inventory/gce/gce.py", line 214, in node_to_dict

    'gce_public_ip': inst.public_ips[0],

IndexError: list index out of range

only happens when there are nodes without external ips.When given temporary external ips the dynamic inventory proceeds as expected.Not sure if a bug in the gce.py script or elsewhere.
