一、vagrant目录结构

二、Vagrantfile

Vagrant.require_version ">= 1.6.0"

boxes = [
    {
        :name => "k3s-master",
        :eth1 => "10.0.20.110",
        :mem => "2048",
        :cpu => "2"
    },
    {
        :name => "k3s-node1",
        :eth1 => "10.0.20.111",
        :mem => "2048",
        :cpu => "2"
    },
    {
        :name => "k3s-node2",
        :eth1 => "10.0.20.112",
        :mem => "2048",
        :cpu => "2"
    },        
]

Vagrant.configure(2) do |config|

  config.vm.box = "centos/7"
  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 "./labs", "/home/vagrant/labs"
  config.vm.provision "shell", privileged: true, path: "./setup.sh"

end

setup.sh

# install some tools
sudo yum install -y git vim gcc glibc-static telnet

三、执行命令

vagrant up

四、进入到vagrant虚拟机安装

因为vagrant的eth0 是给vagrant ssh用的，所以需要指定k3s-master的
--advertise-address 10.0.20.110 --node-ip 10.0.20.110 --flannel-iface eth1
k3s-node(k3s-node1和k3s-node2)的参数为 --node-ip 10.0.20.110 --flannel-iface eth1
