2. Using yum installation kubeadm, kubelet, kubectl, arranged yum source (omitted)
   yum install -y kubelet kubeadm kubectl
3. Set bridge-nf-call-iptables
   echo "1" > /proc/sys/net/bridge/bridge-nf-call-ip6tables

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/

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

kubeadm join 172.28.128.3:6443 --token vwdg2q.30zc380zz9lia98p \
    --discovery-token-ca-cert-hash sha256:d5f93bb4c2eabe5986d575b808b91dc7be9bcb22eafd93d67c00a3abb4ed0bfd 

## kubectl认证,root用户
export KUBECONFIG=/etc/kubernetes/admin.conf
## 非root用户
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

Network deployment flannel plug

1. Get kube-flannel.yaml file https://github.com/coreos/flannel/blob/master/Documentation/kube-flannel.yml
2. According flannel version of the file in the download mirrors https://quay.io/repository/coreos/flannel
   or usedocker pull quay.io/coreos/flannel:v0.11.0-arm64
3. Deployment flannel
   kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Add node node

1. Ibid environment initialization
2. Use kubeadm join 172.28.128.3:6443 --token vwdg2q.30zc380zz9lia98p \ --discovery-token-ca-cert-hash sha256:d5f93bb4c2eabe5986d575b808b91dc7be9bcb22eafd93d67c00a3abb4ed0bfdjoin master node
3. View node information
   kubectl get node
