查看pod状态
kubectl get pods -n kube-system

查看node是否准备就绪
kubectl get node

kubectl get secret -n kube-system

kubectl describe secrets dashboard-admin-token-7ltw8  -n kube-system

kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin

Your Kubernetes master 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

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/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join 192.168.153.128:6443 --token 1o23xt.qf6jkgkxvzhty0sd --discovery-token-ca-cert-hash sha256:35dd4c040df635e068eff89a8dd85ac75feccc7d4ed728503010786110f0f2bd
