Welcome to the kube-router wiki!
Kube-router consist of 3 core components
Network services controller is responsible for reading the services and endpoints information from Kubernetes API server and configure IPVS accordingly.
Please read blog for design details and pros and cons compared to iptables based Kube-proxy https://cloudnativelabs.github.io/post/2017-05-10-kube-network-service-proxy/
Demo of Kube-router's IPVS based Kubernetes network service proxy
Features:
- round robin load balancing
- client IP based session persistence
- source IP is preserved if service controller is used in conjuction with network routes controller (kube-router with --run-router flag)
- option to explicitly masquerade (SNAT) with --masquerade-all flag
Network policy controller is responsible for reading the namespace, network policy and pods information from Kubernetes API server and configure iptables accordingly to provide ingress filter to the pods.
Please read blog for design details of Network Policy controller https://cloudnativelabs.github.io/post/2017-05-1-kube-network-policies/
