+# == Class: tripleo::loadbalancer::endpoint
+#
+# Configure a HAProxy listen endpoint
+#
+# [*internal_ip*]
+# The IP in which the proxy endpoint will be listening in the internal
+# network.
+#
+# [*service_port*]
+# The default port on which the endpoint will be listening.
+#
+# [*ip_addresses*]
+# The ordered list of IPs to be used to contact the balancer member.
+#
+# [*server_names*]
+# The names of the balancer members, which usually should be the hostname.
+#
+# [*member_options*]
+# Options for the balancer member, specified after the server declaration.
+# These should go in the member's configuration block.
+#
+# [*public_virtual_ip*]
+# Address in which the proxy endpoint will be listening in the public network.
+# If this service is internal only this should be ommited.
+# Defaults to undef.
+#
+# [*mode*]
+# HAProxy mode in which the endpoint will be listening. This can be undef,
+# tcp, http or health.
+# Defaults to undef.
+#
+# [*haproxy_listen_bind_param*]
+# A list of params to be added to the HAProxy listener bind directive.
+# Defaults to undef.
+#
+# [*listen_options*]
+# Options specified for the listening service's configuration block (in
+# HAproxy terms, the frontend).
+# defaults to {'option' => []}
+#
+# [*public_ssl_port*]
+# The port used for the public proxy endpoint if it differs from the default
+# one. This is used only if SSL is enabled, and it's used in order to avoid
+# overriding with the internal proxy endpoint (which could happen if they were
+# in the same network).
+# Defaults to undef.
+#
+# [*public_certificate*]
+# Certificate path used to enable TLS for the public proxy endpoint.
+# Defaults to undef.
+#
