+# [*enable_haproxy_wrapper*]
+#  (Optional) If true, generates a wrapper for running haproxy in
+#  a docker container.
+#  Defaults to false
+#
+# [*haproxy_process_wrapper*]
+#   (Optional) If set, generates a haproxy wrapper in the specified file.
+#   Defaults to undef
+#
+# [*haproxy_image*]
+#   (Optional) Docker image name for haproxy. Required if
+#   haproxy_process_wrapper is set.
+#   Defaults to undef
+#
+# [*bind_sockets*]
+#   (Optional) Domain sockets that the wrappers should use for accessing
