+# == Define Resource Type: haproxy::balancermember
+#
+# This type will setup a balancer member inside a listening service
+# configuration block in /etc/haproxy/haproxy.cfg on the load balancer.
+# currently it only has the ability to specify the instance name,
+# ip address, port, and whether or not it is a backup. More features
+# can be added as needed. The best way to implement this is to export
+# this resource for all haproxy balancer member servers, and then collect
+# them on the main haproxy load balancer.
+#
+# === 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 title of the resource is arbitrary and only utilized in the concat
+# fragment name.
+#
+# [*listening_service*]
+# The haproxy service's instance name (or, the title of the
+# haproxy::listen resource). This must match up with a declared
+# haproxy::listen resource.
+#
+# [*ports*]
+# An array or commas-separated list of ports for which the balancer member
+# will accept connections from the load balancer. Note that cookie values
+# aren't yet supported, but shouldn't be difficult to add to the
+# configuration. If you use an array in server_names and ipaddresses, the
+# same port is used for all balancermembers.
+#
+# [*server_names*]
+# The name of the balancer member server as known to haproxy in the
+# listening service's configuration block. This defaults to the
+# hostname. Can be an array of the same length as ipaddresses,
+# in which case a balancermember is created for each pair of
+# server_names and ipaddresses (in lockstep).
+#
+# [*ipaddresses*]
+# The ip address used to contact the balancer member server.
+# Can be an array, see documentation to server_names.
+#
+# [*options*]
+# An array of options to be specified after the server declaration
+# in the listening service's configuration block.
+#
+#
+# === Examples
+#
+# Exporting the resource for a balancer member:
+#
+# @@haproxy::balancermember { 'haproxy':
+# listening_service => 'puppet00',
+# ports => '8140',
+# server_names => $::hostname,
+# ipaddresses => $::ipaddress,
+# options => 'check',
+# }
+#
+#
+# Collecting the resource on a load balancer
+#
+# Haproxy::Balancermember <<| listening_service == 'puppet00' |>>
+#
+# Creating the resource for multiple balancer members at once
+# (for single-pass installation of haproxy without requiring a first
+# pass to export the resources if you know the members in advance):
+#
+# haproxy::balancermember { 'haproxy':
+# listening_service => 'puppet00',
+# ports => '8140',
+# server_names => ['server01', 'server02'],
+# ipaddresses => ['192.168.56.200', '192.168.56.201'],
+# options => 'check',
+# }
+#
+# (this resource can be declared anywhere)
+#
+define haproxy::balancermember (
+ $listening_service,
+ $ports,
+ $server_names = $::hostname,
+ $ipaddresses = $::ipaddress,
+ $options = ''
+) {
+ # Template uses $ipaddresses, $server_name, $ports, $option
+ concat::fragment { "${listening_service}_balancermember_${name}":
+ order => "20-${listening_service}-${name}",
+ target => '/etc/haproxy/haproxy.cfg',
