KUBE_GCE_ENABLE_IP_ALIASES=true will enable allocation of PodCIDR ips using the ip alias mechanism rather than using routes. NODE_IP_RANGE will control the node instance IP cidr KUBE_GCE_IP_ALIAS_SIZE controls the size of each podCIDR IP_ALIAS_SUBNETWORK controls the name of the subnet created for the cluster
