kubekey 部署内置 haproxy k8s 高可用集群
本文主要是介绍kubekey 部署内置 haproxy k8s 高可用集群，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
内置 haproxy 高可用架构：
1、下载脚本
[root@master1 ~]# curl -sfL https://get-kk.kubesphere.io | VERSION=v2.0.0 sh -
如果访问 Github 和 Googleapis 受限先执行以下命令再执行上面的命令
export KKZONE=cn
2、给脚本赋予执行权限
[root@master1 ~]# chmod +x kk
3、创建包含默认配置的示例配置文件（我这里只创建的是 k8s 配置文件，没创建 kubesphere 配置文件，kubesphere 配置文件根据自己的需要创建。）
[root@master1 ~]# ./kk create config --with-kubernetes v1.21.5
4、修改配置文件（这里已经修改好了，根据自己环境修改）
[root@master1 ~]# cat config-sample.yaml
apiVersion: kubekey.kubesphere.io/v1alpha2
kind: Cluster
metadata:
name: sample
spec:
hosts:
- {name: master1, address: 192.168.200.3, internalAddress: 192.168.200.3, user: root, password: "admin"}
- {name: master2, address: 192.168.200.4, internalAddress: 192.168.200.4, user: root, password: "admin"}
- {name: master3, address: 192.168.200.5, internalAddress: 192.168.200.5, user: root, password: "admin"}
- {name: node1, address: 192.168.200.6, internalAddress: 192.168.200.6, user: root, password: "admin"}
roleGroups:
etcd:

- master2
- master3
control-plane:
- master1
- master2
- master3
worker:
- node1

This is a simple check of your environment.
Before installation, you should ensure that your machines meet all requirements specified at
https://github.com/kubesphere/kubekey#requirements-and-recommendations
Continue this installation? [yes/no]: yes

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
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
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/
You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:
kubeadm join lb.kubesphere.local:6443 --token m3cb1z.v2z7g71uckb0xznt \
--discovery-token-ca-cert-hash sha256:4c8e2926999fe60c375bf1f428c6f102b941719c4c094751cd4666c145548367 \
--control-plane
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join lb.kubesphere.local:6443 --token m3cb1z.v2z7g71uckb0xznt \
--discovery-token-ca-cert-hash sha256:4c8e2926999fe60c375bf1f428c6f102b941719c4c094751cd4666c145548367
