Issue 3694 - Introduce class adblockplus::log::processor and role logprocessor

modules/adblockplus/manifests/log/processor.pp

+# == Class: adblockplus::log::processor
+#
+# A mixin class that defines a set of additional Hiera keys for Fluentd,
+# each of which is examined using function hiera_hash(). This allows for
+# fine-tuning the setup via YAML, but will only be supported as long as
+# Fluentd is actually the sofware behind adblockplus::log resources. This
+# is unlikely to change though, or at least there are no such plans yet.
+#
+# === Hiera:
+#
+# [*fluent::configs*]
+#   A hash of zero or more $title => $parameters items for the definition
+#   of fluentd::config resources via YAML.
+#
+# [*fluent::gems*]
+#   A hash of zero or more $title => $parameters items for the definition
+#   of fluent_gem resources via YAML.
+#
+# [*fluent::plugins*]
+#   A hash of zero or more $title => $parameters items for the definition
+#   of fluent::plugin resources via YAML.
+#
+# === Examples:
+#
+#   # Does not imply inclusion of any other adblockplus::* manifest
+#   include adblockplus::log::processor
+#
+class adblockplus::log::processor {
+
+  $fluent_configs = hiera_hash('fluent::configs', {})
+  create_resources('fluent::config', $fluent_configs)
+
+  $fluent_gems = hiera_hash('fluent::gems', {})
+  create_resources('fluent::gem', $fluent_gems)
+
+  $fluent_plugins = hiera_hash('fluent::plugins', {})
+  create_resources('fluent::plugin', $fluent_plugins)
+}
