Kubernetes CNI Plugins

• https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/network-plugins/

Kubernetes (version 1.3 through to the latest 1.33, and likely onwards) lets you use Container Network Interface (CNI) plugins for cluster networking. You must use a CNI plugin that is compatible with your cluster and that suits your needs. Different plugins are available (both open- and closed- source) in the wider Kubernetes ecosystem.

A CNI plugin is required to implement the Kubernetes network model.

You must use a CNI plugin that is compatible with the v0.4.0 or later releases of the CNI specification. The Kubernetes project recommends using a plugin that is compatible with the v1.0.0 CNI specification (plugins can be compatible with multiple spec versions).
