Kubekey安装Kubernetes-1.24.8的过程介绍

master节点

• • 12.验证-master节点

Kubekey简介

官网文档：https://kubesphere.com.cn/docs/v3.3/installing-on-linux/introduction/kubekey/

Github：https://github.com/kubesphere/kubekey

Github中文文档：https://github.com/kubesphere/kubekey/blob/master/README_zh-CN.md

Kubekey采用Go编写，不像Ansible那样依赖运行环境，可以同时安装 Kubernetes 和 KubeSphere。此外Kubekey还可以对K8S集群做升级、扩缩容、根据Yaml安装插件等操作，对非专业运维的开发人员相当友好。

9.下载kk-master节点

mkdir /opt/kubespherecd /opt/kubesphereexport KKZONE=cncurl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.7 sh -

10.准备配置文件-master节点

cat /opt/kubesphere/k8s-config.yaml
