Multus CNI is a CNI meta-plugin for Kubernetes that enables attaching multiple network interfaces to pods, creating multi-homed pods. It works by delegating to other CNI plugins and follows the Kubernetes Network Custom Resource Definition De-facto Standard for specifying additional interface configurations.

Use cases

• attach multiple network interfaces to kubernetes pods
• create multi-homed pods with separate control plane and data plane networks
• run containerized VNFs in kubernetes
• add vlan or vxlan secondary networks to pods
• separate pod traffic across multiple networks
• chain multiple CNI plugins in kubernetes

When to choose

• your pods need more than one network interface in kubernetes
• you need to isolate control plane and data plane traffic
• you are deploying NFV/VNF workloads on kubernetes
• you need to attach pods to secondary networks via other CNI plugins

When to avoid

• your pods only need the default single pod network
• you are not running kubernetes or a CNI-compatible runtime
• you want a simple overlay network without multi-homing
