Overview

Package cni contains supported CNI version definitions and helpers for managing CNIs in KKP. The CNIs are managed either as addons (e.g. Canal, see the `addons` folder) or via the Applications infra (e.g. Cilium starting from version 1.13.0, see pkg/controller/seed-controller-manager/cni-application-installation-controller).
