Issue 3694 - Introduce module fluent

modules/fluent/manifests/gem.pp

+# == Type: fluent::gem
+#
+# Maintain Fluentd (plugin) gems.
+#
+# Type fluentd::gem is a thin layer around a single Puppet package resource
+# definition, combining the available parameters with ones computed internally
+# (aligned with http://docs.fluentd.org/articles/plugin-management#fluent-gem)
+# and determining the proper default package provider (module fluent includes
+# specialized providers using the gem command that ships with Fluentd, see the
+# *.rb files in modules/fluent/lib/puppet/provider/package for details).#
+#
+# === Parameters:
+#
+# [*ensure*]
+#   Translates directly into the package $ensure parameter.
+#
+# [*name*]
+#   Translates directly into the package $name parameter.
+#
+# [*provider*]
+#   Translates directly into the package $provider parameter.
+#
+# === Examples:
+#
+#   fluent::gem {[
+#     'fluent-plugin-secure-forward',
+#     'fluent-plugin-grep',
+#   ]:
+#     ensure => 'latest',
+#   }
+#
+define fluent::gem (
+  $ensure = 'present',
+  $provider = getparam(Package['fluent'], 'name') ? {
+    /\btd[_\-]/ => 'td_agent_gem',
+    default => 'fluent_gem',
+  }
+) {
+
+  include fluent
+  include stdlib
+
+  # Returns undef if Service['fluent'] is not defined
+  $notify = getparam(Service['fluent'], 'ensure') ? {
+    /^(running|true)$/ => Service['fluent'],
+    default => [],
+  }
+
+  package {$title:
+    ensure => $ensure,
+    name => $name,
+    notify => $notify,
+    provider => $provider,
+    require => Package['fluent'],
+  }
+}
