在docker-ce-17.06.0后引入了一个新的废弃策略，但yum却错误地将此应用到了所有的docker-ce版本上，所以我们只需添加一个忽略选项即可：
还有，在18.06版本的Docker上，不需要同时安装docker-ce-selinux
注意格式

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
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 172.31.189.219:6443 --token r6npjy.59peqgwyyvp300eb \
--discovery-token-ca-cert-hash sha256:2cb56c70069e62679739cfab11fed220b3723435c499a912f0c9f5a3923e861d
