Your out of the box choices are: Lighttpd, Mongrel or Mongrel cluster. You have root and are free to install any stack. Here we cover Mongrel cluster. If you wish to use Mongrel or Lighttpd, then select that option from Bootup Action. If you want to do something else, then select Add a new bootup action. The rails guide covers how to get Mongrel up and running.

Mongrel Cluster

Log into https://xxxxxxxx.fb.joyent.us:10000 as admin
Click Service in the left-hand navigation, then click Bootup Action
From the top of boot-up actions page, click Add New Mongrel Cluster.
Enter a short name (letters, digits, '-' or '_' are allowed, but not spaces) into the Action name field.
Enter a description into Description.
Choose whether you want the action to start (and keep running) right away using the Started? option. You'll most likely want to leave this as Yes
Enter the mongrel cluster file name in Cluster yml file field. This is typically /home/xxxxxxxx/web/config/mongrel_cluster.yml
Enter rails application root into Rails root directory field. This is typically /home/xxxxxxxx/web/.
Click Create.
Select your newly created action to see that the mongrels did start up correctly. Besides the Started processes you should see the list of running processes and their statistics.

Example Mongrel_cluster.yml

port: "8000"
environment: production
address: 127.0.0.1
pid_file: log/mongrel.pid
log_file: log/mongrel.log 
servers: 2
