"No network settings" warning for pods not in running state

[jdef]

Periodically this warning appears in the k8s apiserver logs:

W1217 20:14:02.332606   22621 rest.go:238] No network settings: api.ContainerStatus{State:api.ContainerState{Waiting:(*api.ContainerStateWaiting)(0xc208314fc0), Running:(*api.ContainerStateRunning)(nil), Termination:(*api.ContainerStateTerminated)(nil)}, RestartCount:0, PodIP:"", Image:"kubernetes/pause:latest"}
W1217 20:21:30.153627   22621 rest.go:238] No network settings: api.ContainerStatus{State:api.ContainerState{Waiting:(*api.ContainerStateWaiting)(0xc208678420), Running:(*api.ContainerStateRunning)(nil), Termination:(*api.ContainerStateTerminated)(nil)}, RestartCount:0, PodIP:"", Image:"kubernetes/pause:latest"}
W1217 21:24:30.065444   22621 rest.go:238] No network settings: api.ContainerStatus{State:api.ContainerState{Waiting:(*api.ContainerStateWaiting)(0xc208790610), Running:(*api.ContainerStateRunning)(nil), Termination:(*api.ContainerStateTerminated)(nil)}, RestartCount:0, PodIP:"", Image:"kubernetes/pause:latest"}

It's seems clear that since the net container is still in a Pending state that it's completely valid to not have yet been assigned a PodIP. So k8s really shouldn't be logging warnings here.

Data point: it took about 45 min of running my looping replication controller resizer to start generating these.
