K8S需要先安装docker-ce（docker的社区版本，目前K8S不支持18.06以上的版本）
安装docker-ce
yum-config-manager --add-repo http://mirrors.cloud.aliyuncs.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
如果不行改成下面这样
[docker-ce-stable]

yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

Master节点
kubeadm init --kubernetes-version=1.12.3 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=master节点的IP
等了半天报错，原因是下载镜像失败
报错是因为我们是民主国家，你懂的，提供以下两种方案
1 手动方案
先修改默认存储位置和镜像加速
echo '{"registry-mirrors": ["<a ],"graph"="" href="https://registry.docker-cn.com" rel="nofollow">https://registry.docker-cn.com"],"graph": "/data/docker"}' > /etc/docker/daemon.json
systemctl enable docker
systemctl start docker

所有节点
mkdir -p /data/operations/script/
以上镜像操作部分可以批量执行的shell脚本(需要公网IP)

kubeadm token create --print-join-command
二、所有节点通用操作

[root@k8s-m ~]# yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

如果缺少部分镜像请到阿里云的容器镜像服务中搜索，下载后重新TAG
