Install Multus and Whereabouts for Container Networking

This topic gives an overview of the Multus and Whereabouts packages, and how to install them in Tanzu Kubernetes Grid (TKG) workload clusters deployed by a standalone management cluster to provide multiple container networking interface (CNI) and IP Address Management (IPAM) services for the cluster.

Multus lets you attach multiple network interfaces to single pods in a cluster, and Whereabouts lets you associate each network interface with a different address range.

• Multus CNI is an open-source container network interface plugin for Kubernetes that enables attaching multiple network interfaces to pods. See the Multus CNI repository for more information.
• Whereabouts is an open source IPAM CNI plugin you can use with Multus to assign IP addresses to pods cluster-wide dynamically. See the Whereabouts Overview for more information.
