Customizing and tuning the Kuryr SDN for Red Hat OpenShift 3.11 on Red Hat OpenStack 13

In a previous article, I showed you how to customize Red Hat OpenShift software-defined networking (SDN) for your organization’s requirements and restrictions. In this article, we’ll look at using the Kuryr SDN instead. Using Kuryr with OpenShift 3.11 on Red Hat OpenStack 13 changes the customization requirements because Kuryr works directly with OpenStack Neutron and Octavia.

Note: This article builds on the discussion and examples from my previous one. I recommend reading the previous one first.

Background

Traditional OpenShift installations leverage openshift-sdn, which is specific to OpenShift. Using openshift-sdn means that your containers run on a network within a network. This setup, known as double encapsulation, introduces an additional layer of complexity, which becomes apparent when troubleshooting network issues. Double encapsulation also affects network performance due to the overhead of running a network within a network.
