# == Class: puppet-haproxy
#
# A Puppet module, using storeconfigs, to model an haproxy configuration.
# Currently VERY limited - assumes Redhat/CentOS setup. Pull requests accepted!
#
# === 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
#
# [*enable*]
# Chooses whether haproxy should be installed or ensured absent.
# Currently ONLY accepts valid boolean true/false values.
#
# [*haproxy_global_options*]
# A hash of all the haproxy global options. If you want to specify more
# than one option (i.e. multiple timeout or stats options), pass those
# options as an array and you will get a line for each of them in the
# resultant haproxy.cfg file.
#
# [*haproxy_defaults_options*]
# A hash of all the haproxy defaults options. If you want to specify more
# than one option (i.e. multiple timeout or stats options), pass those
# options as an array and you will get a line for each of them in the
# resultant haproxy.cfg file.
#
#
# === Examples
#
# class { 'haproxy':
# enable => true,
# haproxy_global_options => { 'log' => "${::ipaddress} local0",
# 'chroot' => '/var/lib/haproxy',
# 'pidfile' => '/var/run/haproxy.pid',
# 'maxconn' => '4000',
# 'user' => 'haproxy',
# 'group' => 'haproxy',
# 'daemon' => '',
# 'stats' => 'socket /var/lib/haproxy/stats'
# },
# haproxy_defaults_options => { 'log' => 'global',
# 'stats' => 'enable',
# 'option' => 'redispatch',
# 'retries' => '3',
# 'timeout' => ['http-request 10s',
# 'queue 1m',
# 'connect 10s',
# 'client 1m',
# 'server 1m',
# 'check 10s'],
# 'maxconn' => '8000'
# },
#
# }
