README.md

Corporate Usage

In a corporate environment it may be necessary to set multiple proxies each for a different service. In this particular case the best solution that I have been able to find is to use an environment file loaded up with the [dotenv plugin][1]. This file can be setup to use the environment variable values from the runtime shell, e.g. the bash shell that you're executing the vagrant commands from.

Usage

  $ vagrant plugin install dotenv
  $ vagrant plugin install vagrant-proxyconf

Vagrantfile

begin
  require 'dotenv'
  if File.exists?(File.join(Dir.home, '.vagrant.d', 'env'))
    Dotenv.load(File.join(Dir.home, '.vagrant.d', 'env'))
  end
  
  Dotenv.load
rescue LoadError => e
  # TODO: Spew something to standard error as a warning. This should not stop execution
  # as it may have been intended to not exist. 
end
  
Vagrant.configure('2') do |config|
  if Vagrant.has_plugin?('vagrant-proxyconf')
    vagrant.proxy.enabled = ENV.fetch('HTTP_PROXY', false)
  end 
end
