yum install kubelet-1.11.2 kubectl-1.11.2 kubeadm-1.11.2
kubeadm init --kubernetes-version=v1.11.2

查看需要的镜像列表

kubeadm config images list --kubernetes-version=1.11.2
k8s.gcr.io/kube-apiserver-amd64:v1.11.2
k8s.gcr.io/kube-controller-manager-amd64:v1.11.2
k8s.gcr.io/kube-scheduler-amd64:v1.11.2
k8s.gcr.io/kube-proxy-amd64:v1.11.2
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd-amd64:3.2.18
k8s.gcr.io/coredns:1.1.3

由于国内下载镜像拉不到

docker pull 

registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver-amd64:v1.11.2
registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager-amd64:v1.11.2

registry.cn-hangzhou.aliyuncs.com/google_containers/etcd-amd64:3.2.18
registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.1.3

修改tag

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver-amd64:v1.11.2 k8s.gcr.io/kube-apiserver-amd64:v1.11.2
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager-amd64:v1.11.2 k8s.gcr.io/kube-controller-manager-amd64:v1.11.2

docker.io/calico/typha                                                 v3.3.7              46ffe8db5322        7 months ago        55.3 MB docker.io/calico/node                                                  v3.3.7              3c0076aa43ee        7 months ago        75.2 MB docker.io/calico/cni

calico网络，默认是ipip模式（在每台node主机创建一个tunl0网口，这个隧道链接所有的node容器网络，官网推荐不同的ip网段适合，比如aws的不同区域主机），

修改成BGP模式，它会以daemonset方式安装在所有node主机，每台主机启动一个bird(BGP
client)，它会将calico网络内的所有node分配的ip段告知集群内的主机，并通过本机的网卡eth0或者ens33转发数据；

下载calico 权限和配置文件
kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml

wget https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

修改calico.yaml

修改ipip模式关闭和typha_service_nam

- name: CALICO_IPV4POOL_IPIP
  value: "off"
    
- name: IP_AUTODETECTION_METHOD
  value: "interface=ens.*"

2）修改replicas

  replicas: 1
  revisionHistoryLimit: 2

3）修改pod的网段CALICO_IPV4POOL_CIDR

- name: CALICO_IPV4POOL_CIDR
value: "10.244.0.0/16"

4）如果手动下载镜像请查看calico.yaml 文件里面标注的镜像版本否则可以直接执行会自动下载
5）部署calico

kubectl apply -f calico.yaml
