 #### Validating Your `cri` Setup
 A Kubernetes incubator project, [cri-tools](https://github.com/kubernetes-sigs/cri-tools), includes programs for exercising CRI implementations. More importantly, cri-tools includes the program `critest` which is used for running [CRI Validation Testing](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-node/cri-validation.md).

 ### Cons
 * **User Adoption**:
   * Ideally, Kubernetes users don't interact with the underlying container runtime directly. However, for the lack of debug toolkits, sometimes users still need to login the node to debug with Docker CLI directly.
-  * Containerd provides barebone CLIs [ctr](https://github.com/containerd/containerd/tree/main/cmd/ctr) and [dist](https://github.com/containerd/containerd/tree/main/cmd/dist) for development and debugging purpose, but they may not be sufficient and necessary. Additionally, presuming these are sufficient and necessary tools, a plan and time would be needed to sufficiently document these CLIs and educate users in their use.

 ### Out of Scope
 Following items are out of the scope of this design, we may address them in future version as enhancement or optimization.
 * **Debuggability**: One of the biggest concern of CRI-containerd is debuggability. We should provide equivalent debuggability with Docker CLI through `kubectl`, [`cri-tools`](https://github.com/kubernetes-sigs/cri-tools) or containerd CLI.
-* **Built-in CRI support**: The [plugin model](https://github.com/containerd/containerd/blob/main/design/plugins.md) provided by containerd makes it possible to directly build CRI support into containerd as a plugin, which will eliminate one more hop from the stack. But because of the [limitation of golang plugin](https://github.com/containerd/containerd/issues/563), we have to either maintain our own branch or push CRI plugin upstream.

 * **Seccomp**: ([#36997](https://github.com/kubernetes/kubernetes/issues/36997)) Seccomp is supported in OCI runtime spec. However, current seccomp implementation in Kubernetes is experimental and docker specific, the api needs to be defined in CRI first before CRI-containerd implements it.
 * **Streaming server authentication**: ([#36666](https://github.com/kubernetes/kubernetes/issues/36666)) CRI-containerd will be out-of-process with Kubelet, so it could not reuse Kubelet authentication. Its streaming server should implement its own authentication mechanism.
 * **Move container facilities into pod cgroup**: Container facilities including container image puller, container streaming handler, log handler and containerd-shim serve a specific container. They should be moved to the corresponding pod cgroup, and the overhead introduced by them should be charged to the pod.

 Next week we will be working towards a full PoC with the runtime, storage, and fetching of images.  Getting the core functionality up and running quickly is important to us to ensure that integration between the different subsystems in the core flow well together.  We want to make sure the responsibilities of pulling an image from a remote source do not spill into the storage layer and vice-versa.
