Ask an OpenShift Admin Office Hour - CNI plugins and Multus

Red Hat

Recommended Posts

Pods communicate with each other across the network, but how do they connect to the network? The Container Network Interface (CNI) provides a standardized way for network providers to allow Pods to connect. Red Hat OpenShift, via Multus, allows Pods to connect to more than one CNI at the same time. This week’s stream we were joined by three guests: Marc Curry, Product Manager for Red Hat OpenShift, along with Doug Smith and Tomo Hayashi, from the OpenShift engineering team. Together we had a discussion and exploration of CNI plugins, their function and purpose, how they interact with Pods, and some troubleshooting tips.
