start on runlevel [2345]
stop on runlevel [!2345]

respawn              # respawn the service if it dies
respawn limit 5 10   # stop respawning if it fails 5 times in 10 seconds

pre-start script
  mkdir -p /var/run/god  # create gods pid directory, you might not need this
end script

script
  . /etc/profile.d/phoenix.sh             # load environment variables, you might replace or not need this at all
  export RBENV_ROOT="/usr/local/rbenv"    # set required rbenv variable
  # launch god via rbenv NOT daemonized, loads a centralized config in /etc/god.conf
  exec /usr/local/rbenv/bin/rbenv exec god -D -c /etc/god.conf 

  # could not get this working without the -D flag and any expect behaviour,
  # see http://upstart.ubuntu.com/cookbook/#expect for more information
  # this paragraph supported my decision: 
  #   "If your daemon has a "don't daemonize" or "run in the foreground" mode, then it's much simpler to use that and not run
  #   with fork following. One issue with that though, is that Upstart will emit the started JOB=yourjob event as soon as it has 
  #   executed your daemon, which may be before it has had time to listen for incoming connections or fully initialize."

end script

Just what I was looking for. Thanks!
