Description of problem:

when I create a simple service type LoadBalancer, the cluster cannot assign an external ip and the service remains stuck in pending status:

NAME          CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
egress-test   172.30.38.195   <pending>     9999/TCP   4m


Version-Release number of selected component (if applicable):
3.3

How reproducible:
reliably.


Steps to Reproduce:
please find instructions here to create the cluster in google cloud:
https://github.com/raffaelespazzoli/openshift-enablement-exam

and here to reproduce the service problem
https://github.com/raffaelespazzoli/openshift-enablement-exam/blob/master/misc/egress/setup-egress-test.md


Actual results:
pending status forever


Expected results:
external ip assigned to the service and load balancing on google cloud rules created by the openshift.


Additional info:

here is the log from the master service controller:
