 ### 3.初始化Kubeadm
 #### 3.1 默认使用containerd初始化
-如果使用kube-vip，则修改以下配置：--apiserver-advertise-address=<vip>， apiserver-advertise-address参数的地址指向预先分配好的ip地址。
+##### 如果想要配置集群高可用，参考：[使用kube-vip给k8s集群配置vip](kube-vip/README.md)
 ```bash
 # 默认使用containerd初始化
 kubeadm init --kubernetes-version=v1.25.2 --apiserver-advertise-address=192.168.88.110 --image-repository registry.aliyuncs.com/google_containers --pod-network-cidr=10.244.0.0/16 --cri-socket /var/run/containerd/containerd.sock

+### 配置集群高可用
+#### 1.创建Kube-vip的静态pod
+kube-vip的pod需要先于k8s集群创建，因此我们采用static pod方式来创建kube-vip的pod。
+在三台master服务器上执行以下命令（VIP和网卡名根据实际情况修改）
+```bash 
+export VIP=192.168.88.200
+export INTERFACE=enp0s18
+
+KVVERSION=$(curl -sL https://api.github.com/repos/kube-vip/kube-vip/releases | jq -r ".[0].name")
+
+alias kube-vip="ctr run --rm --net-host ghcr.io/kube-vip/kube-vip:$KVVERSION vip /kube-vip"
+
+kube-vip manifest pod \
+    --interface $INTERFACE \
+    --address $VIP \
+    --controlplane \
+    --services \
+    --arp \
+    --leaderElection | tee /etc/kubernetes/manifests/kube-vip.yaml
