I just spent some time helping a user who's struggling to deploy a basic template in dev preview. Among other issues we ran into, the database pod failed to start because: 1) it took 7 minutes before the persistent volume claim was bound 2) once it was bound, the container stayed in "ContainerCreating" state for several minutes (should be several seconds). Presumably these are both infrastructure problems (not sure what the binding issue would be, but the container create is probably a bad node or an unhealthy docker daemon on a node).
Though the PVC was bound to the PV, I would expect that the actual PV was not provisioned in AWS (can be seen in the PV json where the volume ID is just a placeholder while the EBS volume is provisioned in AWS). This is an issue that we are currently experiencing with Online Dev Preview. *** This bug has been marked as a duplicate of bug 1392650 ***
