Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 192.168.137.135:6443 --token abcdef.0123456789abcdef \
        --discovery-token-ca-cert-hash sha256:92b160a90ef52d9e75741414ff84a084c7c4705af9ffcb7705aa344e2e304fbe
root@ubuntu:~/k8s_install_pkg# mkdir -p $HOME/.kube
root@ubuntu:~/k8s_install_pkg# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
root@ubuntu:~/k8s_install_pkg# sudo chown $(id -u):$(id -g) $HOME/.kube/config
root@ubuntu:~/k8s_install_pkg#
root@ubuntu:~/k8s_install_pkg#
root@ubuntu:~/k8s_install_pkg# ll

master节点初始化成功后：

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

这三个步骤需要操作么，需要再node节点做一遍么？
