Execute gitlab sidekiq (rake task) with upstart

Question

I'm trying start the gitlab sidekiq daemon through upstart. But unfortunately it seems that the sidekiq worker is respawned since sidekiq start deamonizes itself:

Jul 12 17:26:42 git kernel: [370722.042968] init: gitlab-sidekiq main process (28251) terminated with status 1
Jul 12 17:26:42 git kernel: [370722.042997] init: gitlab-sidekiq main process ended, respawning

Is there a way to "undemonise" a rake task? (I'm a aware of this and this) Or specifically run gitlab sidekiq as upstart script. Here's my current work so far:

description "Sidekiq Background Worker for Gitlab"

# no "start on", we don't want to automatically start
start on runlevel [2345]
stop on runlevel [!2345]

# change to match your deployment user
setuid git
setgid git

env HOME=/home/git
env PATH="/usr/local/rvm/gems/ruby-1.9.3-p429@gitlab/bin:/usr/local/rvm/gems/ruby-1.9.3-p429/bin:/usr/local/rvm/gems/ruby-1.9.3-p429@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p429/bin:/usr/local/rvm/bin:/usr/bin:/bin"
env GEM_PATH="/usr/local/rvm/gems/ruby-1.9.3-p429@gitlab:/usr/local/rvm/gems/ruby-1.9.3-p429@global"
env RAILS_ENV="production"
respawn
respawn limit 3 30

script
# this script runs in /bin/sh by default
  cd /home/git/gitlab
  exec bundle exec rake sidekiq:start
end script

I was able to fix the script. Since sidekiq:start deamonizes itself I needed to put it into a post-start and post-stop environment.

# /etc/init/gitlab-sidekiq.conf - Sidekiq config for gitlab

# use the service command:
#   sudo service gitlab-sidekiq {start,stop,restart,status}

description "Sidekiq Background Worker for Gitlab"

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

# change to match your deployment user
setuid git
setgid git

env HOME=/home/git
env PATH="/usr/local/rvm/gems/ruby-1.9.3-p429@gitlab/bin:/usr/local/rvm/gems/ruby-1.9.3-p429/bin:/usr/local/rvm/gems/ruby-1.9.3-p429@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p429/bin:/usr/local/rvm/bin:/usr/bin:/bin"
env GEM_PATH="/usr/local/rvm/gems/ruby-1.9.3-p429@gitlab:/usr/local/rvm/gems/ruby-1.9.3-p429@global"
env RAILS_ENV="production"

post-start script
  cd /home/git/gitlab
  exec bundle exec rake sidekiq:start
end script


post-stop script
  cd /home/git/gitlab
  exec bundle exec rake sidekiq:stop
end script
