Creating a Multi-Machine Vagrant Environment
By using a "Vagrantfile within a Vagrantfile" structure, we can create code that allows Vagrant to provision an environment comprised of multiple machines. This lets us create Vagrant environments that closely mimic production, separating out databases, services, applications, and more as needed. In this hands-on lab, we use the LXC provider to create two different machines and establish that the machines can communicate.

Challenge
Create Two Machines
-
Move into the
website
directory and initialize a Vagrantfile:cd website vagrant init
-
Update the Vagrantfile so two containers are created:
vim Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "fgrehm/trusty64-lxc" config.vm.provider "lxc" config.vm.define "web" do |web| end config.vm.define "db" do |db| end end

Challenge
Configure the Private Network
Still editing your Vagrantfile, add a private network to each guest:
Vagrant.configure("2") do |config| config.vm.box = "fgrehm/trusty64-lxc" config.vm.provider "lxc" config.vm.define "web" do |web| web.vm.network "private_network", ip: "192.168.2.110", lxc__bridge_name: "brdg" end config.vm.define "db" do |db| db.vm.network "private_network", ip: "192.168.2.111", lxc__bridge_name: "brdg" end end
Save and exit the file.
