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.

Zookeeper Platform


Apache ZooKeeper is an effort to develop and maintain an open-source server which enables highly reliable distributed coordination. Learn more about ZooKeeper on

This cookbook focuses on deploying a Zookeeper cluster via Chef on systemd managed distributions.


Cookbooks and gems

Declared in metadata.rb and in Gemfile.


A systemd managed distribution: - RHEL Family 7, tested on Centos

Note: it should work fine on Debian 8 but the official docker image does not allow systemd to work easily, so it could not be tested.


Easy Setup

Create a role zookeeper-platform having recipe['zookeeper-platform'] in its runlist and setting node['zookeeper-platform']['role'] to itself. Add this role in the runlists of the nodes you want to use for your cluster. By default, you need exactly 3 nodes.

By default, this cookbook installs openjdk from the official repositories (openjdk 8 on centos 7) in systemd-service recipe, just before launching the service. You can deactivate this behavior by setting node['zookeeper-platform']['java'] to "", or choose your package by setting the package name in node['zookeeper-platform']['java'][node[:platform]].

By default, the config recipe use a search to find the members of a cluster. The search is parametrized by a role name, defined in attribute node['zookeeper-platform']['role'] which default to zookeeper-platform. Node having this role in their expanded runlist will be considered in the same zookeeper cluster. For safety reason, if search is used, you need to define node['zookeeper-platform']['size'] (3 by default). The cookbook will return (with success) until the search return size nodes. This ensures the stability of the configuration during the initial startup of a cluster.

If you do not want to use search, it is possible to define node['zookeeper-platform']['hosts'] with an array containing the hostnames of the nodes of a zookeeper cluster. In this case, size attribute is ignored and search deactivated.


This cookbook is fully tested through the installation of a working 3-nodes cluster in docker hosts. This uses kitchen, docker and some monkey-patching.

For more information, see .kitchen.yml and test directory.

Local cluster

You can also use this cookbook to install a zookeeper cluster locally. By running kitchen converge, you will have a 3-nodes cluster available on your workstation, each in its own docker host. You can then access it with: -server $(docker inspect \
  --format '{{.NetworkSettings.IPAddress}}' zookeeper-kitchen-01)


Configuration is done by overriding default attributes. All configuration keys have a default defined in attributes/default.rb. Please read it to have a comprehensive view of what and how you can configure this cookbook behavior.



Run install, create-user, config and systemd-service recipes, in that order.


Install zookeeper with ark cookbook.


Create zookeeper system user and group.


Generate nodes list by search or by using hosts attribute. Merge it with base configuration, then install myid and zoo.cfg files. Create work directories: for data and logs.


Install zookeeper service for systemd, enable and start it. Install java package by default.




Available in CHANGELOG.
