Development repository for Opscode Cookbook application_php

branch: master
README.md

Description

This cookbook is designed to be able to describe and deploy PHP web applications. Currently supported:

  • PHP
  • Apache2 with mod_php

Note that this cookbook provides the PHP-specific bindings for the application cookbook; you will find general documentation in that cookbook.

Other application stacks may be supported at a later date.

Requirements

Chef 0.10.0 or higher required (for Chef environment use).

The following Opscode cookbooks are dependencies:

  • application
  • apache2
  • php

Resources/Providers

The LWRPs provided by this cookbook are not meant to be used by themselves; make sure you are familiar with the application cookbook before proceeding.

php

The php sub-resource LWRP deals with deploying PHP webapps from an SCM repository. It uses the deploy_revision LWRP to perform the bulk of its tasks, and many concepts and parameters map directly to it. Check the documentation for deploy_revision for more information.

PHP applications have no standard convention for database configuration; your application cookbook must provide a template if needed.

Attribute Parameters

  • packages: an Array of PEAR packages to install
  • database_master_role: if a role name is provided, a Chef search will be run to find a node with than role in the same environment as the current role. If a node is found, its IP address will be used when rendering the context file, but see the "Database block parameters" section below
  • local_settings_file: the name of the local settings file to be generated by template. Defaults to "LocalSettings.php"
  • settings_template: the name of template that will be rendered to create the local settings file. Defaults to "#{local_settings_file}.erb"
  • database: a block containing additional parameters for configuring the database connection (see below)
  • app_root: path where the application can be found in relative from path. Default value is "/"

Database block parameters

The database block can accept any method, which will result in an entry being created in the @database Hash which is passed to the context template. See the examples below for more information.

mod_php_apache2

The mod_php_apache2 sub-resource LWRP configures Apache and mod_php to run the application by creating a virtual host.

Attribute Parameters

  • server_aliases: an Array of server aliases
  • webapp_template: the template to render to create the virtual host configuration. Defaults to "php.conf.erb"

Usage

A sample application that needs a database connection:

application "phpvirtualbox" do
  path "/usr/local/www/sites/phpvirtualbox"
  owner node[:apache][:user]
  group node[:apache][:user]
  repository "..."
  deploy_key "..."
  revision "4_0_7"
  packages ["php-soap"]

  php do
    database_master_role "database_master"
    local_settings_file "config.php"
  end

  mod_php_apache2
end

This will result in a config.php file getting created from a config.php.erb template that must exist in your application cookbook.

You can invoke any method on the database block:

application "my-app" do
  path "/usr/local/my-app"
  repository "..."
  revision "..."

  php do
    database_master_role "database_master"
    database do
      database 'name'
      quorum 2
      replicas %w[Huey Dewey Louie]
    end
  end
end

The corresponding entries will be passed to the context template:

<%= @database['quorum']
<%= @database['replicas'].join(',') %>
