+# == Define: elasticsearch::instance
+#
+# This define allows you to create or remove an elasticsearch instance
+#
+# === Parameters
+#
+# [*ensure*]
+# String. Controls if the managed resources shall be <tt>present</tt> or
+# <tt>absent</tt>. If set to <tt>absent</tt>:
+# * The managed software packages are being uninstalled.
+# * Any traces of the packages will be purged as good as possible. This may
+# include existing configuration files. The exact behavior is provider
+# dependent. Q.v.:
+# * Puppet type reference: {package, "purgeable"}[http://j.mp/xbxmNP]
+# * {Puppet's package provider source code}[http://j.mp/wtVCaL]
+# * System modifications (if any) will be reverted as good as possible
+# (e.g. removal of created users, services, changed log settings, ...).
+# * This is thus destructive and should be used with care.
+# Defaults to <tt>present</tt>.
+#
+# [*status*]
+# String to define the status of the service. Possible values:
+# * <tt>enabled</tt>: Service is running and will be started at boot time.
+# * <tt>disabled</tt>: Service is stopped and will not be started at boot
+# time.
+# * <tt>running</tt>: Service is running but will not be started at boot time.
+# You can use this to start a service on the first Puppet run instead of
+# the system startup.
+# * <tt>unmanaged</tt>: Service will not be started at boot time and Puppet
+# does not care whether the service is running or not. For example, this may
+# be useful if a cluster management software is used to decide when to start
+# the service plus assuring it is running on the desired node.
+# Defaults to <tt>enabled</tt>. The singular form ("service") is used for the
+# sake of convenience. Of course, the defined status affects all services if
+# more than one is managed (see <tt>service.pp</tt> to check if this is the
+# case).
+#
+# [*config*]
+# Elasticsearch configuration hash
+#
+# [*configdir*]
+# Path to directory containing the elasticsearch configuration.
+# Use this setting if your packages deviate from the norm (/etc/elasticsearch)
+#
+# [*datadir*]
+# Allows you to set the data directory of Elasticsearch
+#
+# [*logging_file*]
+# Instead of a hash you can supply a puppet:// file source for the logging.yml file
+#
+# [*logging_config*]
+# Hash representation of information you want in the logging.yml file
+#
+# [*logging_template*]
+# Use a custom logging template - just supply the reative path ie ${module}/elasticsearch/logging.yml.erb
+#
+# [*logging_level*]
+# Default logging level for Elasticsearch.
+# Defaults to: INFO
+#
+# [*init_defaults*]
+# Defaults file content in hash representation
+#
