如何在VagrantFile中包含变量？

Can anyone guide me to how do I include variables in my VagrantFile? I am trying to inject configs into the Vagrantfile from an external file so that I can distribute the config to my colleagues without having them to hardcode configs directly on the Vagrantfile.

任何人都可以指导我如何在我的VagrantFile中包含变量？我试图从外部文件将配置注入Vagrantfile，这样我就可以将配置分发给我的同事，而无需直接在Vagrantfile上硬编码配置。

I had thought that since it was Ruby based I could just include a Ruby file but I get an error Message: unintialized constant MyVars

我曾经想过，因为它是基于Ruby的我可以只包含一个Ruby文件，但是我得到一个错误消息：unintialized constant MyVars

My VagrantFile simplified

我的VagrantFile简化了

# -*- mode: ruby -*-
# vi: set ft=ruby :
require 'vagrant.rb'
include MyVars

Vagrant.configure("2") do |config|

  # Web
  config.vm.define :joe do |joe|
    joe.vm.box = "precise64_4.2.12"
    joe.vm.hostname = WEBVMNAME
    joe.vm.network :private_network, ip: "192.168.140.141"

    # Port Forwarding
    joe.vm.network :forwarded_port, guest: 22, host: 2201
    joe.vm.network :forwarded_port, guest: 80, host: 8080

    # Bootstrap Bash Script
    joe.vm.provision :shell, :path => "bootstrap.sh"
  end

end

And vagrant.rb contains

而vagrant.rb包含

module MyVars

    WEBVMNAME = "rex"

end

Do note that I am also a newbie at Ruby so I am not sure as well if its just the syntax I got wrong?

请注意我也是Ruby的新手，所以我不确定它是否只是我的错误的语法？

I use the approach of https://puphpet.com, I create a file config.yaml in the same directory of the Vagrantfile and...

我使用https://puphpet.com的方法，在Vagrantfile的同一目录中创建一个文件config.yaml，然后...

In my Vagrantfile:

在我的Vagrantfile中：

# encoding: utf-8
# -*- mode: ruby -*-
# vi: set ft=ruby :

require 'yaml'

current_dir    = File.dirname(File.expand_path(__FILE__))
configs        = YAML.load_file("#{current_dir}/config.yaml")
vagrant_config = configs['configs'][configs['configs']['use']]

Vagrant.configure('2') do |config|

    config.vm.network 'public_network', ip: vagrant_config['public_ip']
    ...

In my config.yaml:

在我的config.yaml中：

---
configs:
    use: 'home'
    office:
        public_ip: '192.168.2.117'
        <more variables>...
    home:
        public_ip: '192.168.1.117'
        <more variables>...

#2

Use require_relative:

使用require_relative：

require_relative 'vagrant.rb'
include MyVars
# ...

#3

Try changing your require to this:

尝试将您的要求更改为：

require './vagrant'

#4

I created a library directory:

我创建了一个库目录：

require './lib/cfpEnvironment.rb'
include CFPEnvironment

And then did the scripting of what I need to be dynamic, defining the variables in the module created...

然后编写了我需要动态的脚本，在创建的模块中定义变量......

CFPPorts.select{ |key, value| value.numeric? }.each { |key, value|
   config.vm.network :forwarded_port, guest: value, host: value
}
