k8s脚本自动搭建

1、脚本搭建
如 kubetcl、docker 一些网络插件、一行命令自动搭建

1)先执行以下命令以确保您从正确的区域下载 KubeKey。

export KKZONE=cn

2)Kubekey

curl -sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh -

安装成功的界面

3)给kk授权

查看一下
chmod +x kk

4)创建config

./kk create config --with-kubernetes v1.18.6 --with-kubesphere v3.0.0
查看是否有config

5)开启可插拔组件
