Getting started with Fig and Wordpress
======================================
Fig makes it nice and easy to run Wordpress in an isolated environment. [Install Fig](install.html), then write a `Dockerfile` which installs PHP and Wordpress:
```
FROM orchardup/php5
ADD http://wordpress.org/wordpress-3.8.1.tar.gz /wordpress.tar.gz
RUN tar -xzf /wordpress.tar.gz
ADD wp-config.php /wordpress/wp-config.php
ADD router.php /router.php
```
This instructs Docker on how to build an image that contains PHP and Wordpress. For more information on how to write Dockerfiles, see the [Dockerfile tutorial](https://www.docker.io/learn/dockerfile/) and the [Dockerfile reference](http://docs.docker.io/en/latest/use/builder/).
Next up, `fig.yml` starts our web service and a separate MySQL instance:
```
web:
build: .
command: php -S 0.0.0.0:8000 -t /wordpress
ports:
- 8000:8000
links:
- db
db:
image: orchardup/mysql
ports:
- 3306:3306
environment:
MYSQL_DATABASE: wordpress
```
Our Dockerfile relies on two supporting files - first up, `wp-config.php` is the standard Wordpress config file with a single change to make it read the MySQL host and port from the environment variables passed in by Fig:
```
<?php
define('DB_NAME', 'wordpress');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
define('DB_HOST', getenv("DB_1_PORT_3306_TCP_ADDR") . ":" . getenv("DB_1_PORT_3306_TCP_PORT"));
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
define('AUTH_KEY', 'put your unique phrase here');
define('SECURE_AUTH_KEY', 'put your unique phrase here');
define('LOGGED_IN_KEY', 'put your unique phrase here');
define('NONCE_KEY', 'put your unique phrase here');
define('AUTH_SALT', 'put your unique phrase here');
define('SECURE_AUTH_SALT', 'put your unique phrase here');
define('LOGGED_IN_SALT', 'put your unique phrase here');
define('NONCE_SALT', 'put your unique phrase here');
$table_prefix = 'wp_';
define('WPLANG', '');
define('WP_DEBUG', false);
if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'wp-settings.php');
```
Finally, `router.php` tells PHP's built-in web server how to run Wordpress:
```
<?php
$root = $_SERVER['DOCUMENT_ROOT'];
chdir($root);
$path = '/'.ltrim(parse_url($_SERVER['REQUEST_URI'])['path'],'/');
set_include_path(get_include_path().':'.__DIR__);
if(file_exists($root.$path))
{
if(is_dir($root.$path) && substr($path,strlen($path) - 1, 1) !== '/')
$path = rtrim($path,'/').'/index.php';
if(strpos($path,'.php') === false) return false;
else {
chdir(dirname($root.$path));
require_once $root.$path;
}
}else include_once 'index.php';
```
With those four files in place, run `fig up` and it'll pull and build the images we need, and then start the web and database containers. You'll then be able to visit Wordpress and set it up by visiting [localhost:8000](http://localhost:8000) - or [localdocker:8000](http://localdocker:8000) if you're using docker-osx.
