puppet-zookeeper: A Ruby repository from Ziaunys

#puppet-zookeeper

A puppet receipt for Apache Zookeeper. ZooKeeper is a high-performance coordination service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

Requirements

Puppet 2.7, Puppet 3.x
Ruby 1.8.7, 1.9.3, 2.0.0, 2.1.x
binary package of ZooKeeper

Basic Usage:

class { 'zookeeper': }

If $::ipaddress is not your public IP (e.g. you are using Docker) make sure to setup correct IP:

class { 'zookeeper':
  client_ip => $::ipaddress_eth0
}

or in Hiera:

zookeeper::client_ip: "%{::ipaddress_eth0}"

Parameters

id - cluster-unique zookeeper's instance id (1-255)
datastore
log_dir
purge_interval - automatically will delete zookeeper logs (available since 3.4.0)
snap_retain_count - number of snapshots that will be kept after purging (since 3.4.0)

and many others, see the init.pp file for more details.

If your distribution has multiple packages for ZooKeeper, you can provide all package names as an array.

class { 'zookeeper':
  packages => ['zookeeper', 'zookeeper-java']
}

Hiera Support

All parameters could be defined in hiera files, e.g. common.yaml, Debian.yaml or zookeeper.yaml:

zookeeper::id: 1
zookeeper::client_port: 2181
zookeeper::datastore: '/var/lib/zookeeper'

Cloudera package

In Cloudera distribution ZooKeeper package does not provide init scripts (same as in Debian). Package containing init scripts is called zookeeper-server and the service as well. Moreover there's initialization script which should be called after installation. So, the configuration might look like this:

class { 'zookeeper':
  packages             => ['zookeeper', 'zookeeper-server'],
  service_name         => 'zookeeper-server',
  initialize_datastore => true
}

Managing repository

For RedHat family curretly we support also managing an yum repo. It can be enabled with repo parameter:

class { 'zookeeper':
  repo => 'cloudera'
}

Java installation

Default: false

By changing these two parameters you can ensure, that given Java package will be installed before ZooKeeper packages.

class { 'zookeeper':
  install_java => true,
  java_package => 'openjdk-7-jre-headless'
}
