简介：

搭建过 k8s 童鞋应该都懂搭建的痛苦，现分享 k8s 三主两从高可用架构虚拟机镜像，下载后直接导入 vmware 虚拟机即可，省去搭建烦恼，直接开始 k8s 学习之旅。

环境

系统：CentOS 7.9 内核版本：6.4
Kubernetes ：v1.28.0
etcd ： 3.5.9
helm：3.12.3

节点分布

192.168.1.51  - 192.168.1.53 为 master 节点，用 nginx 做高可用，etcd 做共享存储
192.168.1.54  - 192.168.1.55 为 node 节点

k8s三主两从高可用架构虚拟机镜像

k8s 三主两从高可用架构虚拟机镜像

k8s 虚拟机下载：https://www.aliyundrive.com/s/G27E2ZNYYwd
文件里面有 .mp4 后缀的删除 .mp4 即可，阿里云盘对文件的限制

若是用默认 3.x 版本内核会出现很多 bug，k8s 都建议升级到 5.x 版本以上，本镜像升级到最新稳定版本。
github 上有很多人都测试了的，一下是其中之一
