daemonizing sidekiq with upstart script - is not w

I'm trying to daemonize sidekiq using two upstart scripts following this example. Basically the workers service starts a fixed number of sidekiq services.

The problem is that the sidekiq script fails at the line of code where I am starting sidekiq. I've tried to run the command directly in bash and it works fine.

I tried all different commented lines and none works.

So my question is what am I doing wrong? Where can I see the error messages?

This is my modified sidekiq script:

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

# This example config should work with Ubuntu 12.04+.  It
# allows you to manage multiple Sidekiq instances with
# Upstart, Ubuntu's native service management tool.
#
# See workers.conf for how to manage all Sidekiq instances at once.
#
# Save this config as /etc/init/sidekiq.conf then mange sidekiq with:
#   sudo start sidekiq index=0
#   sudo stop sidekiq index=0
#   sudo status sidekiq index=0
#
# or use the service command:
#   sudo service sidekiq {start,stop,restart,status}
#

exec /bin/bash <<EOT
  # use syslog for logging
  # exec &> /dev/kmsg

  # pull in system rbenv
  # export HOME=/home/deploy
  # source /etc/profile.d/rbenv.sh

  cd /home/rails
  touch /root/sidekick_has_started
  sidekiq -i ${index} -e production
  # exec sidekiq -i ${index} -e production
  # exec /usr/local/rvm/gems/ruby-2.0.0-p353/gems/sidekiq-3.1.3/bin/sidekiq -i ${index} -e production
  touch /root/sidekick_has_started_2
EOT
end script

You are right, RVM env are required to be loaded in. Try this:

.....    
.....

script
exec /bin/bash <<EOT

  #export HOME=/home/deploy
  source /usr/local/rvm/environments/ruby-2.0.0-p353@global

  cd /home/rails
  exec sidekiq -i ${index} -e production

.....    
.....

Does it work?
