如何使用 Ruby 模板化 Vagrantfile？

Question

我有几个 Vagrantfile，每个对应一个不同的 provider，因为 Vagrant 有一个限制，不允许同时使用两个或多个规定同样的Vagrantfile。所以，我分成两个或更多 Vagrantfiles，但我的 "body"，我的规定脚本对两者都是相同的，唯一改变的是 provider 块。

例如：

local_nagios/Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

require 'yaml'
set = YAML.load_file '../../../settings.yaml'

Vagrant.configure(2) do |nagios|

  nagios.vm.provider :virtualbox do |provider, override|
    override.vm.box = 'ubuntu/trusty64'
    override.vm.hostname = 'nagios.company.com'
    override.vm.synced_folder '.', '/vagrant', disabled:true
    override.vm.network 'public_network', bridge:set['network_interface'], ip:set['dev_nagios_ip']

    provider.memory = 4096
    provider.cpus = 2
  end

  install = set['devops_home'] + '/vagrant/lib/install'
  nagios.vm.provision 'shell', path: install + '/basic'
  nagios.vm.provision 'shell', path: install + '/devops'

  step = set['devops_home'] + '/vagrant/server/nagios/steps'
  nagios.vm.provision 'shell', path: step + '/install', args: [set['nagios_password']]

end

digital_nagios/Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

require 'yaml'
set = YAML.load_file '../../../settings.yaml'

Vagrant.configure(2) do |nagios|

  nagios.vm.provider :digital_ocean do |provider, override|
    override.vm.box = 'digital_ocean'
    override.vm.hostname = 'nagios.company.com'
    override.vm.synced_folder '.', '/vagrant', disabled:true
    override.ssh.private_key_path = '~/.ssh/id_rsa'

    provider.token = 'my-token'
    provider.image = 'ubuntu-14-04-x64'
    provider.region = 'fra1'
    provider.size = '4gb'
  end

  install = set['devops_home'] + '/vagrant/lib/install'
  nagios.vm.provision 'shell', path: install + '/basic'
  nagios.vm.provision 'shell', path: install + '/devops'

  step = set['devops_home'] + '/vagrant/server/nagios/steps'
  nagios.vm.provision 'shell', path: step + '/install', args: [set['nagios_password']]

end

我想知道是否可以以此制作模板。或者像这样导入我的公共区域：

Vagrant.configure(2) do |nagios|

  nagios.vm.provider :digital_ocean do |provider, override|
    ...
  end

  import '../provision.rb'

end

我不熟悉 Ruby，所以任何建议将不胜感激！

你可以这样做

Vagrant.configure(2) do |nagios|

  nagios.vm.provider :digital_ocean do |provider, override|
    ...
  end

  eval File.read("../Vagrantfile-common")

end
