 * Associate the `opsworks_custom_env::configure` custom recipe with the _Deploy_ event in your rails app's layer.
 
 A deploy isn't necessary if you just want to update the custom configuration. Instead, update the stack's custom JSON, then choose to _Run Command_ > _execute recipes_ and enter `opsworks_custom_env::configure` into the _Recipes to execute_ field. Executing the recipe will write an updated `application.yml` file and restart unicorn workers.
