HAProxy is an HA proxying daemon for load-balancing to clustered services. It can proxy TCP directly, or other kinds of traffic such as HTTP.

This haproxy uses storeconfigs to collect and realize balancer member servers on a load balancer server. Currently Redhat family OSes are supported.

To install and configure HAProxy server listening on port 80

node 'haproxy-server' {
  class { 'haproxy': }
  haproxy::listen { 'puppet00':
    ipaddress => $::ipaddress,
    ports     => '8140',
  }
}

To add backend loadbalance members

node 'webserver01' {
  @@haproxy::balancermember { $fqdn:
    listening_service => 'puppet00',
    server_names      => $::hostname,
    ipaddresses       => $::ipaddress,
    ports             => '8140',
    options           => 'check'
  }
}

The base haproxy class can accept two parameters which will configure basic behaviour of the haproxy server daemon:

• global_options to configure the global section in haproxy.cfg
• defaults_options to configure the defaults section in haproxy.cfg

One haproxy::listen defined resource should be defined for each HAProxy loadbalanced set of backend servers. The title of the haproxy::listen resource is the key to which balancer members will be proxied to. The ipaddress field should be the public ip address which the loadbalancer will be contacted on. The ports attribute can accept an array or comma-separated list of ports which should be proxied to the haproxy::balancermemeber nodes.

The haproxy::balacemember defined resource should be exported from each node which is serving loadbalanced traffic. the listening_service attribute will associate it with haproxy::listen directives on the haproxy node. ipaddresses and ports will be assigned to the member to be contacted on. If an array of ipaddresses and server_names are provided then they will be added to the config in lock-step.

Tested and built on Ubuntu and CentOS
