Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

application_procfile Cookbook

This cookbook installs initscripts and monitrc files for the different process types specified in your application's Procfile.



  • application - application_procfile needs the application cookbook to discover a Procfile.
  • monit - application_procfile needs the monit cookbook to configure services under monit.


  • foreman - application_procfile uses the foreman gem's Procfile parser.



depends 'application_procfile'


include_recipe 'application_procfile'

application 'someapp' do
  procfile do
    web node[:someapp][:processes][:web] || 1, :reload => 'USR2', :health_check => { :path => '/system/status', :timeout => 10, :unhealthy => 10, :action => :alert }, :limit => { :totalmem => '512 MB', :unhealthy => 10 }
    worker node[:someapp][:processes][:worker] || 2, :limit => { :totalmem => '192 MB' }

This will run a default of 1 web and 2 workers for a Procfile that looks like:

web: bundle exec unicorn -c ./config/unicorn.rb
worker: bundle exec rake resque:work

Any output to stderr or stdout from your processes will be logged to files like:


To restart your workers:

touch /var/local/someapp/worker.restart

The reload option specifies an optional signal that can be sent to processes to gracefully reload them by doing:

touch /var/local/someapp/web.reload

If the process is unicorn a HUP and USR2 combination will be used automatically, with no need for the reload option.

To properly support reloads for unicorn processes, a unicorn.rb with before_fork, correct paths and worker numbers will be installed in the shared directory and will include your config/unicorn.rb if you have one.

You can specify resource limits with the :limit option, such as :mem, :totalmem, :cpu, :totalcpu, or :children.

For :mem and :totalmem the value is the maximum allowable memory for the process or the process and all it's children, respectively, as B, KB, MB, GB, or %. (eg. :limit => { :totalmem => '512 MB' })

For :cpu, and :totalcpu the value is the maxmimum allowable CPU usage for the process or the process and all it's children, respectively, as %. (eg. :limit => { :totalcpu => '90%' })

For :children the value is the maximum number of child processes allowed for the process. (eg. :limit => { :children => 10 })

Within :limit you can specify the action to be taken :alert, :restart, or :stop when any of the limits are exceeded. (eg. :limit => { :cpu => '25%', :action => :alert })

You can also specify the number of times the limits must exceed their values before taking action using :unhealthy. (eg. :limit => { :mem => '10%', :unhealthy => 10 })

You can specify a health check with the :health_check option as long as the port your service is listening on is accessible via node attribute as node[:app][:port] or you specify a :port in your health check. (eg. :health_check => { :port => 8080, :path => '/system/status', :timeout => 10, :unhealthy => 10, :action => :alert })
