Kube-router is project that provides one cohesive solution that provides CNI networking for pods, an IPVS based network service proxy and iptables based network policy enforcement.

Kube-router also provides a service proxy, so kube-proxy will not be deployed in to the cluster.

Installing kube-router on a new Cluster

The following command sets up a cluster with Kube-router.

export ZONES=mylistofzones
kops create cluster \
  --zones $ZONES \
  --networking kube-router \
  --yes \


No additional configurations are required to be done by user. Kube-router automatically disables source-destination check on all AWS EC2 instances. For the traffic within a subnet there is no overlay or tunneling used. For cross-subnet pod traffic ip-ip tunneling is used implicitly and no configuration is required.
