 == Using Host Networking
 
-You can choose to let the pods use the networking of the host that
-they are on rather than containerizing the networking and using
-the SDN.  This is how the router works, and it can be a useful
-technique when you have to proxy a Layer 7 protocol that is not
-http/https/or TLS with SNI.  You can look at the way the router is
-configured to see how to set it up, but basically you need to set
-`hostNetwork: true` in the pod definition, and then run the router
-with a service account that has the `hostnetwork` permission.  You can
-grant the permission with `oc adm policy add-scc-to-user hostnetwork

-Once configured, the pod can access all of the network interfaces on

-This allows you to make your own proxy, or allows you to run a program
-directly on the host interfaces directly.
