Multiple machines

You can configure a Vagrantfile for multiples VMs at the same time.

You need to use the function vm.define is the main VM configuration like the following configuration.

Vagrant.configure("2") do |config|
  config.vm.provision "shell", inline: "echo Common provisioning"

  config.vm.define "web" do |web|
    web.vm.box = "ubuntu/xenial64"
    web.vm.provision "shell", inline: "echo Provisioning for Web only"
  end

  config.vm.define "db" do |db|
    db.vm.box = "ubuntu/xenial64"
    db.vm.provision "shell", inline: "echo Provisioning for Db only"
  end
end

Try to run this configuration.
You should see two VMs starting each provisionning the common part and it’s custom part.

By default, your vagrant ssh will connect to the main vm (the first configured).
You can change it with :

config.vm.define "web", primary: true do |web|
  # ...
end

You can also choose the connection VM with vagrant ssh db
