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.

Puma Cookbook

Chef cookbook for the puma server.

The defaults assume you are deploying with capistrano and will write all configuration and logs to the shared/puma directory... However the configuration should be flexible enough to support any deployment setup.

The cookbook will also setup scripts to support restarts and phased restarts.

By default puma_config will enable monit monitoring and log rotation via logrotate.


monit, logrotate


The cookbook contains two definitions: puma_install and puma_config.

The puma_install definition allows you to install multiple instances of puma in different ruby environments by changing the gem_bin_path parameter... but you are not required to use it to install puma if your tool/workflow installs puma differently.

The default recipe simply calls puma_install. If you plan on using puma_install directly you don't need to include the the default recipe in your run list.

The puma_config defintion will create a puma configuration, stop/start scripts and configure monit to watch the puma process. It can be used with or without using puma_install.

Basic puma configuration using defaults based off the application name:

puma_config "app"

Custom config overriding app settings. In this example the configuration files and helper scripts will be placed in /srv/app/shared/puma.

For example - in the following example to do a 'phased-restart' (zero downtime deploy) after deploying your code you would run the /srv/app/shared/puma/ script.

puma_config "app" do
  directory "/srv/app"
  environment 'staging'
  monit false
  logrotate false
  thread_min 0
  thread_max 16
  workers 2

Common Settings

directory: Working directory of your app. This is where is.

puma_directory: directory where sockets, state and logs will be stored. Defaults to <directory>/shared/puma

environment: (default = production)

bind: defults to unix socket (at unix:///srv/app/shared/puma/app.sock) can speficy TCP socket instead such as "tcp://"

exec_prefix: default bundle exec

thread_min: min number of threads in puma threadpool

thread_max: max number of threads in puma threadpool

workers: number of worker processes defaults to 0, must be greater than 0 for phased restarts

monit: (true) set to false to disable monit functionality

logrotate: (true) set to false to disable logrotate functionality
