This article is part of a series.
If you are working behind a proxy server you will need to configure both the host computer and the Vagrant virtual machines to communicate through the proxy server. It is easy to configure the proxy settings but finding the documentation is a different story. Below we will go through how to configure the proxy for the vagrant commands (up, status, box add, etc) and then how to configure the virtual machine proxy settings.
In order for the Vagrant commands that talk out to the internet to work there are several environment variables that need to be set.
The typical proxy environment variables are http_proxy and https_proxy. You can either permanently set them so they are always available or you can set them only for the current open command prompt/terminal.
Current Open Command Prompt
set http_proxy=http://yourproxyserver:port set https_proxy=https://yourproxyserver:port
setx http_proxy=http://yourproxyserver:port setx https_proxy=https://yourproxyserver:port
View Proxy Settings
If the commands below just echo out the text instead of the actual proxy server, it means that the proxy server is not set.
echo %http_proxy% echo %https_proxy%
Removing Proxy Setting
Unfortunately there is no way to remove the proxy settings from the command line without issuing a reg delete. For whatever reason, Microsoft only allows you to blank out an environment variable with setx but not remove it. Luckily, this does make it so that Vagrant will not use a proxy to connect to the internet.
Vagrant Boxes (Virtual Machines)
vagrant plugin install vagrant-proxyconf
The vagrant-proxyconf can configure the proxy settings for Generic Proxy environment variables, Chef, Apt, Docker, Git, npm, PEAR, Subversion, Yum, and Windows.
Below we will walk through the basics of using the vagrant-proxyconf plugin. You can read the full documentation at https://github.com/tmatilai/vagrant-proxyconf.
Ensuring the plugin is installed
There is no built-in vagrant command to make sure that a plugin is installed but since the Vagrantfile is a Ruby file, it is very easy to write a little bit of Ruby code to ensure that the plugin is installed.
In the Vagrantfile before the Vagrant.configure(2) do |config| line added the following code snippet:
if !Vagrant.has_plugin?("vagrant-proxyconf") system('vagrant plugin install vagrant-proxyconf') raise("vagrant-proxyconf installed. Run command again."); end
Generic Proxy Settings
You can either configure the Vagrant proxy settings on a per Vagrant virtual machine basis or globally.
To configure on a per machine basis, add the code snippet below to the the machines VagrantFile.
To configure global add the code snippet below to VagrantFile at .vagrant.d/Vagrantfile. You may need to create this file. To learn more about a global VagrantFile and the order that the VagrantFile’s are read see http://docs.vagrantup.com/v2/vagrantfile/.
Vagrant.configure("2") do |config| if Vagrant.has_plugin?("vagrant-proxyconf") config.proxy.http = "http://192.168.0.2:3128/" config.proxy.https = "http://192.168.0.2:3128/" config.proxy.no_proxy = "localhost,127.0.0.1,.example.com" end # ... rest of the configurations end
Now you have everything you need to configure Vagrant to work from behind a proxy server. In the next lesson we will cover the different networking options for Vagrant.
