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.
