# == Define Resource Type: apache::balancer
#
# This type will create an apache balancer cluster file inside the conf.d
# directory. Each balancer cluster needs one or more balancer members (that can
# be declared with the apache::balancermember defined resource type). Using
# storeconfigs, you can export the apache::balancermember resources on all
# balancer members, and then collect them on a single apache load balancer
# server.
#
# === Requirement/Dependencies:
#
# Currently requires the puppetlabs/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 balancer clusters name.
# This name is also used in the name of the conf.d file
#
# [*proxy_set*]
# Hash, default empty. If given, each key-value pair will be used as a ProxySet
# line in the configuration.
#
# [*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
# apache::balancermember with array arguments, which allows you to deploy
# everything in 1 run)
#
#
# === Examples
#
# Exporting the resource for a balancer member:
#
# apache::balancer { 'puppet00': }
#

$proxy_set = {},
