# Architecture of The CRI Plugin # Architecture of The CRI Plugin
This document describes the architecture of the `cri` plugin for `containerd`. This document describes the architecture of the `cri` plugin for `containerd`.
This plugin is an implementation of Kubernetes [container runtime interface (CRI)](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/apis/cri/runtime/v1alpha2/api.proto). Containerd operates on the same node as the [Kubelet](https://kubernetes.io/docs/reference/generated/kubelet/). The `cri` plugin inside containerd handles all CRI service requests from the Kubelet and uses containerd internals to manage containers and container images.

The `cri` plugin uses containerd to manage the full container lifecycle and all container images. As also shown below, `cri` manages pod networking via [CNI](https://github.com/containernetworking/cni) (another CNCF project).
