KubeKey底层基于kubeadm快速部署K8S集群

1.安装依赖软件包
apt -y install socat conntrack ebtables ipset
2.设置区域
export KKZONE=cn
3.下载kubekey文件
wget https://github.com/kubesphere/kubekey/releases/download/v3.1.10/kubekey-v3.1.10-linux-amd64.tar.gz
wget http://192.168.21.253/Resources/Kubernetes/Project/kubesphere/kubersphere-on-linux/kube-key-v3.1.10_k8s-v1.28.12/kubekey-v3.1.10-linux-amd64.tar.gz

4.解压软件包
tar xf kubekey-v3.1.10-linux-amd64.tar.gz

5.生成安装配置文件模板
./kk create config --with-kubernetes v1.28.12
6.修改安装配置文件
