如何在VagrantFile中包含变量？

问题描述

有人可以指导我如何在VagrantFile中包含变量吗？我试图从外部文件将配置注入Vagrantfile，以便我可以将配置分发给我的同事，而无需他们直接在Vagrantfile上对配置进行硬编码。

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.

I曾以为，由于它是基于Ruby的，所以我只能包含一个Ruby文件，但出现错误
消息：未初始化的常量MyVars

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

我的VagrantFile简化了

My VagrantFile simplified

# -*- 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

.rb包含

module MyVars

    WEBVMNAME = "rex"

end

请注意，我也是Ruby的新手，所以我不确定它是否只是我弄错了语法吗？

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?

推荐答案

我使用的方法，我在Vagrantfile的同一目录中创建了一个文件config.yaml。 ..

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

在我的Vagrantfile中：

In my Vagrantfile:

# 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']
    ...

在我的config.yaml中：

In my config.yaml:

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