I have install firecracker-containerd in my machine and can run container use the flow command 

firecracker-ctr --address /run/firecracker-containerd/containerd.sock run  --rm --tty --net-host docker.io/library/debian:latest test

I want use it with kubelet. Is it right? I change kubelet config as below. 

# /var/lib/kubelet/kubeadm-flags.env
KUBELET_EXTRA_ARGS="--container-runtime=remote --container-runtime-endpoint=unix:///run/firecracker-containerd/containerd.sock"

But, kubelet failed as follow errors.

failed to create kubelet: get remote runtime typed version failed: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService

I properly misunderstand. The right way may be kubelet - containerd - firecracker-containerd. Trying on this.

firecracker-containerd is not CRI conformant and therefore will not work with kubernetes. https://github.com/firecracker-microvm/firecracker-containerd/issues/88 tracks conformance, but we're not there yet.
