We now use an attribute named `backend_servers`. Collection and the attributes of each element mirror those of the data bag. 11 | 12 | ## v1.1.0: 13 | 14 | * Forked and modified to pull configuration data from a data bag. 15 | 16 | ## v1.0.4: 17 | 18 | * [COOK-806] - load balancer should include an SSL option 19 | * [COOK-805] - Fundamental haproxy load balancer options should be configurable 20 | 21 | ## v1.0.3: 22 | 23 | * [COOK-620] haproxy::app_lb's template should use the member cloud private IP by default 24 | 25 | ## v1.0.2: 26 | 27 | * fix regression introduced in v1.0.1 28 | 29 | ## v1.0.1: 30 | 31 | * account for the case where load balancer is in the pool 32 | 33 | ## v1.0.0: 34 | 35 | * Use `node.chef_environment` instead of `node['app_environment']` 36 | 37 | Requirements 38 | ============ 39 | 40 | ## Platform 41 | 42 | Tested on Ubuntu 8.10 and higher. 43 | 44 | ## Cookbooks: 45 | 46 | Attributes 47 | ========== 48 | 49 | * `node['haproxy']['incoming_port']` - sets the port on which haproxy listens 50 | * `node['haproxy']['enable_admin']` - whether to enable the admin interface. default true. Listens on port 22002. 51 | * `node['haproxy']['balance_algorithm']` - sets the load balancing algorithm; defaults to roundrobin. 52 | * `node['haproxy']['member_max_connections']` - the maxconn value to be set for each app server 53 | * `node['haproxy']['x_forwarded_for']` - if true, creates an X-Forwarded-For header containing the original client's IP address. This option disables KeepAlive. 54 | * `node['haproxy']['enable_ssl']` - whether or not to create listeners for ssl, default false 55 | * `node['haproxy']['ssl_incoming_port']` - sets the port on which haproxy listens for ssl, default 443 56 | * `node['haproxy']['cookie_insert']` - sets the `cookie_insert` string if you want load balancing based on cookie insertion 57 | * `node['haproxy']['cookie_prefix']` - sets the `cookie_prefix` string if you want to use cookie prefixing 58 | * `node['haproxy']['backend_servers']` - a list of backend server configurations. These will be used to write the configuration file (see below). 59 | 60 | Usage 61 | ===== 62 | 63 | Use either the default recipe or the `app_lb` recipe. 64 | 65 | When using the default recipe, modify the haproxy.cfg.erb file with listener(s) for your sites/servers. 66 | 67 | A sample role, `haproxy_demo` might look like this: 68 | 69 | name "haproxy_demo" 70 | description "demo haproxy recipe" 71 | run_list( 72 | "recipe[haproxy::default]", 73 | "recipe[haproxy::app_lb]", 74 | ) 75 | override_attributes( 76 | "haproxy" => { 77 | 'incoming_port' => "80", 78 | 'balance_algorithm' => "roundrobin", 79 | 'backend_servers' => [ 80 | { 81 | "hostname" => "appserver1.example.com", 82 | "ipaddress" => "192.168.0.1", 83 | "port" => "8080", 84 | "proxy_weight" => 1, 85 | "max_connections" => 100, 86 | "ssl_port" => 443 87 | }, 88 | { 89 | "hostname" => "appserver2.example.com", 90 | "ipaddress" => "192.168.0.2", 91 | "port" => "8080", 92 | "proxy_weight" => 1, 93 | "max_connections" => 100, 94 | "ssl_port" => 443 95 | } 96 | ] 97 | } 98 | ) 99 | 100 | License and Author 101 | ================== 102 | 103 | Author:: Joshua Timberman () 104 | Author:: Brad Montgomery () 105 | Author:: Tim Lowrimore () 106 | 107 | Copyright:: 2009-2012, Opscode, Inc 108 | 109 | Licensed under the Apache License, Version 2.0 (the "License"); 110 | you may not use this file except in compliance with the License. 111 | You may obtain a copy of the License at 112 | 113 | http://www.apache.org/licenses/LICENSE-2.0 114 | 115 | Unless required by applicable law or agreed to in writing, software 116 | distributed under the License is distributed on an "AS IS" BASIS, 117 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 118 | See the License for the specific language governing permissions and 119 | limitations under the License. 120 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
