# == Define Resource Type: haproxy::listen
#
# This type will setup a listening service configuration block inside
# the haproxy.cfg file on an haproxy load balancer. Each listening service
# configuration needs one or more load balancer member server (that can be
# declared with the haproxy::balancermember defined resource type). Using
# storeconfigs, you can export the haproxy::balancermember resources on all
# load balancer member servers, and then collect them on a single haproxy
# load balancer server.
#
# === Requirement/Dependencies:
#
# Currently requires the ripienaar/concat module on the Puppet Forge and
# uses storeconfigs on the Puppet Master to export/collect resources
# from all balancer members.
#
# === Parameters
#
# [*name*]
# The namevar of the defined resource type is the listening service's name.
# This name goes right after the 'listen' statement in haproxy.cfg
#
# [*ports*]
# Ports on which the proxy will listen for connections on the ip address
# specified in the virtual_ip parameter. Accepts either a single
# comma-separated string or an array of strings which may be ports or
# hyphenated port ranges.
#
# [*ipaddress*]
# The ip address the proxy binds to. Empty addresses, '*', and '0.0.0.0'
# mean that the proxy listens to all valid addresses on the system.
#
# [*mode*]
# The mode of operation for the listening service. Valid values are 'tcp',
# HTTP', and 'health'.
#
# [*options*]
# A hash of options that are inserted into the listening service
# configuration block.
#
# [*collect_exported*]
# Boolean, default 'true'. True means 'collect exported @@balancermember resources'
# (for the case when every balancermember node exports itself), false means
# 'rely on the existing declared balancermember resources' (for the case when you
# know the full set of balancermembers in advance and use haproxy::balancermember
# with array arguments, which allows you to deploy everything in 1 run)
#
#
# === Examples
#
# Exporting the resource for a balancer member:
#
# haproxy::listen { 'puppet00':
# ipaddress => $::ipaddress,
# ports => '18140',
# mode => 'tcp',
# options => {
# 'option' => [
# 'tcplog',
# 'ssl-hello-chk'
# ],
# 'balance' => 'roundrobin'
# },
# }
#
# === Authors
#
# Gary Larizza <gary@puppetlabs.com>
#
define haproxy::listen (
$ports,
$ipaddress = [$::ipaddress],
$mode = 'tcp',
$collect_exported = true,
$options = {
'option' => [
'tcplog',
'ssl-hello-chk'
],
'balance' => 'roundrobin'
}
) {
# Template uses: $name, $ipaddress, $ports, $options
concat::fragment { "${name}_listen_block":
order => "20-${name}-00",
target => '/etc/haproxy/haproxy.cfg',
content => template('haproxy/haproxy_listen_block.erb'),
}
if $collect_exported {
Haproxy::Balancermember <<| listening_service == $name |>>
}
# else: the resources have been created and they introduced their
# concat fragments. We don't have to do anything about them.
