containerd as the container runtime

mkdir -p /etc/containerd/
mv containerd-config.toml /etc/containerd/config.toml
mv containerd.service /etc/systemd/system/

kubelet

mv kubelet-config.yaml /var/lib/kubelet/
mv kubelet.service /etc/systemd/system/

kube proxy

mv kube-proxy-config.yaml /var/lib/kube-proxy/
mv kube-proxy.service /etc/systemd/system/

Start these components as systemd and enjoy =))

systemctl daemon-reload
systemctl enable containerd kubelet kube-proxy
systemctl start containerd kubelet kube-proxy
