Thanks. I checked kube-up and it seems kubelet uses both --configure-cbr0 and --network-plugin=kubenet. Kubenet takes precedence, it creates cbr0, but it does not restart docker.
It looks like docker doesn't need to use --bridge=cbr0 when using the kubenet network plugin on kubelet. The pods will still have the IPs from cbr0. If this is correct, then the problem I described previously is not an issue with kubenet. I like to get confirmation if someone knows this is indeed true.
