本文参考使用 KubeKey 内置 HAproxy 创建高可用集群教程安装
如果需要跨网络、跨云组节点，可以先使用V**组网，参考本文omniedge V**异地组网工具使用教程
- 使用
ubuntu 20.04 LTS系统安装 KubeKey版本 v3.0.7kubernetes版本 v1.23.15kubesphere版本 v3.3.2Docker版本 v23.0.1
1. 初始化服务器和安装必要包
参考本文https://cloud.tencent.com/developer/article/2020356
需关闭防火墙、各节点同步时间
代码语言：javascript复制apt install -y socat conntrack 使用一键脚本安装Docker并配置镜像加速，参考本文https://cloud.tencent.com/developer/article/2020351
2. 下载KubeKey工具
代码语言：javascript复制# 配置为国内源加速下载
export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.7 sh -
chmod x kk3. 创建示例配置文件并修改
代码语言：javascript复制# 创建示例配置文件
./kk create config --with-kubernetes v1.23.15 --with-kubesphere v3.3.2 -f config-sample.yaml我的配置文件

4. 使用配置文件安装KubeSphere
代码语言：javascript复制./kk create cluster -f config-sample.yaml看到类似如下信息，则表示安装成功
代码语言：javascript复制#####################################################
### Welcome to KubeSphere! ###
#####################################################
Console: http://192.168.0.3:30880
Account: admin
Password: P@88w0rd
...使用ip 端口访问控制台即可
5. 一键卸载脚本
代码语言：javascript复制./kk delete cluster -f config-sample.yaml注意事项
- 节点最好有4G以上内存，不然会卡，用着不顺畅
- 各节点时间必须同步
- 不能开启swap虚拟内存
- 如果需要开启devops流水线，最好16G内存以上
安装体验了下，对我来说使用没rancher简洁，资源占用太多，端口映射太麻烦。最后还是换回了rancher2.4
