PuppetLabs Module for haproxy

Build Status

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.

Basic Usage

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 8140

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'
  }
}

Configuring haproxy options

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

Configuring haproxy daemon listener

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::balancermember nodes.

Configuring haproxy daemon frontend

One haproxy::frontend defined resource should be defined for each HAProxy front end you wish to set up. 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::backend resources.

Configuring haproxy daemon backend

One haproxy::backend defined resource should be defined for each HAProxy loadbalanced set of backend servers. The title of the haproxy::backend resource is the key to which balancer members will be proxied to. Note that an haproxy::listen resource and haproxy::backend resource can have the same name, and any balancermembers exported to that name will show up in both places. This is likely to have unsatisfactory results, but there's nothing preventing this from happening.

Configuring haproxy loadbalanced member nodes

The haproxy::balancermember 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.
