# == Define Resource Type: haproxy::config
#
# 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
#
# [*virtual_ip_port*]
# A unique port, or a port range for which the proxy will accept connections
# for the ip address specified in the virtual_ip parameter.
#
# [*order*]
# The order, or numerical weight, of the fragment created by this defined
# resource type. This is necessary to ensure the fragment is associated
# with the correct listening service instance.
#
# [*virtual_ip*]
# 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'.
#
# [*haproxy_config_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::config { 'puppet00':
# order => '20',
# virtual_ip => $::ipaddress,
# virtual_ip_port => '18140',
# mode => 'tcp',
# haproxy_config_options => {'option' => ['tcplog', 'ssl-hello-chk'],
# 'balance' => 'roundrobin'},
# }
#
# === Authors
#
# Gary Larizza <gary@puppetlabs.com>
#
define haproxy::config (
$virtual_ip_port,
$order = '20',
$virtual_ip = $::ipaddress,
$mode = 'tcp',
$collect_exported = true,
$haproxy_config_options = {
'option' => [
'tcplog',
'ssl-hello-chk'
],
'balance' => 'roundrobin'
}
) {
concat::fragment { "${name}_config_block":
order => $order,
target => '/etc/haproxy/haproxy.cfg',
content => template('haproxy/haproxy_config_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.
