1. 安装master（第一台master）

1.1 编辑kubeadm配置文件

[root@k8s01 ~]# cat ~/kubeadm-config.yaml
apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers
kubernetesVersion: v1.13.1
controlPlaneEndpoint: k8s-cluster.smile13.com:6443
apiServer:
  certSANs:
    - k8s-cluster.smile13.com
networking:
  serviceSubnet: 10.96.0.0/12
  podSubnet: 10.244.0.0/16

1.2 提前拉取镜像

[root@k8s01 ~]# kubeadm config images pull --config kubeadm-config.yaml 
[config/images] Pulled registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.13.1
