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.

Storm Cluster


Apache Storm is a free and open source distributed
realtime computation system. Storm makes it easy to reliably process unbounded
streams of data, doing for realtime processing what Hadoop did for batch
processing. Storm is simple, can be used with any programming language, and is
a lot of fun to use!


Cookbooks and gems

Declared in [metadata.rb](metadata.rb) and in [Gemfile](Gemfile).


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

Note: it should work quite fine on Debian 8 (with some attributes tuning) but
the official docker image does not allow Systemd to work easily, so it could
not be tested.


Easy Setup

This cookbook creates the number of nodes specified by attribute
node['storm-platform']['size'] (3 by default). The first node to be created
will be setup with a Nimbus, a LogViewer and a UI. All other nodes will host a
Supervisor and a LogViewer. To get this cookbook to setup the nth node to hold
the Nimbus, Supervisor and LogViewer instead of the first one, change attribute

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

The recommended way to use this cookbook is through the creation of a role
per Storm cluster. This enables the search by role feature, allowing a
simple service discovery.

In fact, there are two ways to configure the search:
1. with a static configuration through a list of hostnames (attributes hosts
that is ['storm-platform']['hosts'])
2. with a real search, performed on a role (attributes role and size
like in ['storm-platform']['role']). The role should be in the run-list
of all nodes of the cluster. The size is a safety and should be the number
of nodes in the cluster.

If hosts is configured, role and size are ignored.

See [roles](test/integration/roles) for some examples and
Cluster Search documentation for more information.

Zookeeper Cluster

To install properly a Storm cluster, you need a Zookeeper cluster.
This is not in the scope of this cookbook but if you need one, you should
consider using Zookeeper Platform.

The configuration of Zookeeper hosts use search and is done similarly as for
Storm hosts, ie with a static list of hostnames or by using a search on
a role. The attribute to configure is ['storm-platform']['zookeeper'].


This cookbook is fully tested through the installation of the full platform
in docker hosts. This uses kitchen, docker and some monkey-patching.

If you run kitchen list, you will see 3 suites:

  • zookeeper-centos-7
  • storm-nimbus-centos-7
  • storm-supervisor-centos-7

Each corresponds to a different node in the cluster. They are connected through
a bridge network named kitchen, which is created if necessary.

For more information, see [.kitchen.yml](.kitchen.yml) and [test](test)

Local cluster

The cluster installed with kitchen converge is fully working and can thus be
used as a local cluster for developments tests.

You can access it by using internal DNS of the docker network named kitchen
or by declaring each node in your hosts file. You can get each IP by

docker inspect --format \
  '{{}}' container_name


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



Install and fully configure a given Storm by including the recipes:
install, create_user, config and systemd_service, in that order.


Install Storm from tar archive with ark cookbook.


Create a system user for Storm.


Configure Storm.


Create Systemd service files and set them up. Different Storm services will
be set up following the kind of node (both may apply).

For a nimbus:
- nimbus
- logviewer
- ui

For a supervisor:
- supervisor
- logviewer

Note: install java package (OpenJDK 8 on centos 7) by default, can be
disabled by setting node['confluent-platform']['java'] to "". A platform
specific configuration for the package to install is also possible.
