Setting up a K8S Cluster Quickly with Vagrant + VirtualBox

Objective

Configuration of K8S Cluster Machines

Hostname	IP Address	CPU	Memory	Operating System
k8s-master	192.168.100.10	4	4G	Debian "bookworm"
k8s-worker1	192.168.100.11	2	2G	Debian "bookworm"
k8s-worker2	192.168.100.12	2	2G	Debian "bookworm"

Components and Versions of K8S Cluster

Project	Component	Version
Deployment	kubeadm	v1.30.0
CLI	kubectl	v1.30.0
Node Agent	kubelet	v1.30.0
Container Runtime	CRI-O	v1.30.0
CNI	flannel	v0.25.1

Prerequisites

VirtualBox: Virtualization software.

Vagrant: Virtual machine management tool. Install the following plugins:

vagrant plugin install vagrant-vbguest vagrant-share

Notes

1. This project is not intended for production use.
2. Due to network restrictions in Mainland China, this project uses USTC open source software mirror and Alibaba Cloud Container Registry to accelerate software package downloads. You may need to remove or replace corresponding repository addresses in other regions.
3. When executing vagrant ssh on Windows, you may encounter a permission denied issue. Run the fix_ssh_pkey_perm_for_win.ps1 script to fix the permission issue.
4. This project has been fully tested on Windows. In theory, it should also work fine on other operating systems as the host machine.

使用 Vagrant + VirtualBox 快速搭建 K8S 集群

目标

K8S 集群机器配置

主机名	IP 地址	处理器	内存	操作系统
k8s-master	192.168.100.10	4	4G	Debian "bookworm"
k8s-worker1	192.168.100.11	2	2G	Debian "bookworm"
k8s-worker2	192.168.100.12	2	2G	Debian "bookworm"

K8S 集群组件和版本

项目	组件	版本
部署工具	kubeadm	v1.30.0
命令行工具	kubectl	v1.30.0
节点代理	kubelet	v1.30.0
容器运行时	CRI-O	v1.30.0
CNI	flannel	v0.25.1

依赖环境

VirtualBox：虚拟机软件

Vagrant：虚拟机管理工具，需要安装插件

vagrant plugin install vagrant-vbguest vagrant-share

注意事项

1. 本项目不应用于生产环境。
2. 由于中国大陆地区的网络原因，项目中使用了中科大开源软件镜像和阿里云镜像仓库加速软件包下载，其他地区可能需要移除或替换相应的仓库地址。
3. 在 Windows 上执行 vagrant ssh 会遇到 permission denied 的问题，执行 fix_ssh_pkey_perm_for_win.ps1 脚本修复权限问题。
4. 本项目在 Windows 进行了完整测试，其他操作系统的宿主机理论上也可以正常运行。
