  Problem:
  Many CNI-based plugins do not set hairpin mode which allows pods to access themselves via their Service IP, if they don't know about their podIP.
  CNI Plugins Should allow hairpin traffic containernetworking/cni#476

This is not documented in kubeadm. However kubeam only supports CNI-based plugins and not kubenet-based plugins

Proposed Solution:
It is possible to extend the documentation of the section "Install Pod network" with additional information which network add-ons support hairpin mode?

I can confirm that flannel-cni plugin does not support it.

Page to Update:
k8s.io/docs/setup/independent/create-cluster-kubeadm/

Kubernetes Version:
v1.7.2
