Creating a Multi-Machine Vagrant Environment

1. Move into the website directory and initialize a Vagrantfile:

   cd website
   vagrant init
   

2. 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
   

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.

1. Deploy the environment:

   vagrant up
   

2. Log in to the web guest:

   vagrant ssh web
   

3. View the IP of the guest:

   ifconfig
   

4. ping the db from the web guest:

   ping 192.168.2.111
