1 Introduction to the Multus Module

Multus is a Container Network Interface (CNI) plugin for Kubernetes. Unlike other CNI plugins, Multus doesn't implement pod networking. Multus is a multiplexer for other CNI plugins. By using Multus, it's possible to attach many network interfaces to a single pod.

Multus creates a networking bridge to either Flannel or Calico. For more information on Multus, see the upstream Multus documentation.

You can create NetworkAttachmentDefinitions using a Multus configuration file during the Multus module installation, or you can create NetworkAttachmentDefinitions after the module is deployed using the kubectl command.
