Tried to recreate the GKE cluster to try on Kubernetes 1.2.0

Cluster came up correctly, yet the firs pod deployment is stuck in 'Pending':

[]# kubectl get pods
NAME            READY     STATUS    RESTARTS   AGE
operation-daily   0/1       Pending   0          6m 

Have been following the same script that was used for 1.1.8 (successfully).

Tried a few times - no luck.

How could I diagnose the issue? Would it be possible to go back to 1.1.8 version?
