Windows下傻瓜Vagrant+VirtualBox+shell快速创建3台安装好docker的centos7虚拟机

目标：在Windows上快速创建三台能ping通局域网及公网的安装好docker(自己想装什么软件就装什么软件)的centos7虚拟机

manager:192.168.205.10 worker1:192.168.205.11 worker2:192.168.205.12

提示：还不会用vagrant创建单个虚拟机的请先看这篇：[傻瓜式Vagrant+virtualBox快速创建centos7虚拟机](https://blog.youkuaiyun.com/nowitzkis/article/details/107256793)

下面我们用三分钟来达成这篇文章的目标

1 在D:\vm\centos7\centos7-vm-2目录用Git Bash执行vagrant init centos7初始化Vagrantfile文件并修改该文件

# -*- mode: ruby -*-
# vi: set ft=ruby :
​
Vagrant.require_version ">= 1.6.0"
​
boxes = [
    {
        :name => "manager",
        :eth1 => "192.168.205.10",
        :mem => "1024",
        :cpu => "1"
    },
    {
        :name => "worker1",
        :eth1 => "192.168.205.11",
        :mem => "1024",
        :cpu => "1"
    },
    {
        :name => "worker2",
        :eth1 => "192.168.205.12",
        :mem => "1024",
        :cpu => "1"
    }
]
​
Vagrant.configure(2) do |config|
​
  config.vm.box = "centos7"
  config.ssh.username = 'root'
  config.ssh.password = 'vagrant' 
  config.ssh.insert_key = 'true'
​
  boxes.each do |opts|
      config.vm.define opts[:name] do |config|
        config.vm.hostname = opts[:name]
        config.vm.provider "vmware_fusion" do |v|
          v.vmx["memsize"] = opts[:mem]
          v.vmx["numvcpus"] = opts[:cpu]
        end
​
        config.vm.provider "virtualbox" do |v|
          v.customize ["modifyvm", :id, "--memory", opts[:mem]]
          v.customize ["modifyvm", :id, "--cpus", opts[:cpu]]
        end
​
        config.vm.network :private_network, ip: opts[:eth1]
      end
  end
​
  config.vm.synced_folder ".", "/home/vagrant"
  config.vm.provision "shell", privileged: true, path: "./setup.sh"
​
end
复制代码

2 在D:\vm\centos7\centos7-vm-2目录创建文件setup.sh

# 安装你想安装的工具
sudo yum install -y git vim gcc glibc-static telnet bridge-utils
​
# 安装docker
curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh
​
# 启动docker服务
sudo systemctl start docker
​
#移除安装包
rm -rf get-docker.sh复制代码

3 当前目录打开GitBash，执行vagrant up命令，等待几分钟就ok啦~

简而言之就是根据Vagrantfile文件遍历创建虚拟机并执行shell脚本去初始化虚拟机
