Adding virtual hosts

Moonshine's default_stack recipe comes with one virtual host already setup for you, but you may find yourself wanting to add your own. Reviewing the code for how the passenger vhost is setup is a great way to learn to do this for other virtual hosts.

First, we start with a new template in app/manifests/templates/example.vhost.erb:

# app/manifests/templates/example.vhost.erb
<VirtualHost *:80>
  # interesting stuff goes here
</VirtualHost>

Then in app/manifests/application_manifest.rb we're going to create a new recipe. It will use this template to create a new site in /etc/apache2/sites-available and then enable it.

# app/manifests/application_manifest.rb
class ApplicationManifest < Moonshine::Manifest::Rails
  recipe :default_stack
  
  def example_vhost
    file '/etc/apache2/sites-available/example',
      :ensure => :present,
      :content => template('example.vhost.erb', binding),
      :alias => 'example_vhost',
      :require => package('apache2')

    a2ensite 'example', :require => file('example_vhost')
  end
  recipe :example_vhost
end

Commit, push, and deploy this, and you'll see your new virtual host in action.
