Disable SDN network between Master and Nodes on Red Hat OpenShift Container Platform

Solution In Progress - Updated -

Issue

  • For security reason, we would like to disable the SDN network between master and nodes. Our nodes are located in separate network zones which are separated by firewalls. If all nodes have an SDN connection (udp port 4789) to the masters, it looks like they are all somehow connected together.

Environment

  • Red Hat OpenShift Container Platform 3
