Installation on x86 Servers

On the two x86 servers, install kubelet, kubeadm, kubectl, and the kube-apiserver, kube-scheduler, kube-proxy, kube-controller-manage, pause, and etcd container images by referring to the method of installing kubeadm.

The method is the same as the common Kubernetes installation method.
