# == 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.
#
# [*internal_certificate*]
# Certificate path used to enable TLS for the internal proxy endpoint.
# Defaults to undef.
