1. 介绍
kubespray 是 Kubernetes incubator 中的项目，目标是提供 Production Ready Kubernetes 部署方案，该项目基础是通过 Ansible Playbook 来定义系统与 Kubernetes 集群部署的任务，具有以下几个特点：
可以部署在 AWS, GCE, Azure, OpenStack 以及裸机上.
部署 High Available Kubernetes 集群.
可组合性 (Composable)，可自行选择 Network Plugin (flannel, calico, canal, weave) 来部署.
支持多种 Linux distributions(CoreOS, Debian Jessie, Ubuntu 16.04, CentOS/RHEL7).
本篇将说明如何通过 Kubespray 部署 Kubernetes 至裸机节点，安装版本如下所示：
- kubespray v2.22.1
- Kubernetes v1.26.5
- Etcd 3.5.6
- calico v3.25.1
- containerd v1.7.1
2. 预备条件
通过 vSphere client 创建虚拟机，vSphere client 如何创建虚拟机请看这里。
需求：
系统： Rocky Linux 8.7
CPU: 4
MEM: 8G
DISK1: 30G
DISK2: 50G
配置地址与主机名分别为：
192.168.10.40 bastion01
192.168.10.41 kube-master01
192.168.10.42 kube-master02

14. 配置连接集群
(bastion01操作)
安装 kubectl
dnf -y install golang
curl -LO https://dl.k8s.io/release/v1.26.5/bin/linux/amd64/kubectl
chmod 755 kubectl
mv kubectl /usr/local/bin
bastion01 配置 kubeconfig
mkdir /root/.kube
从kube-master01 节点 /etc/kubernetes/admin.conf 拷贝至bastion01节点 /root/.kube/config
并修改https://127.0.0.1:6443 为 https://192.168.10.41:6443
