Wordpress on Openshift

This is an example of template for deploying Wordpress v5.2.6 on Openshift v3.9. Using persistent storage on MySQL 5.6 and PHP 5.6.

Editing Wordpress Code

You need to add and change wp-config.php database configuration like below to get environment variable from container.

define( 'DB_NAME', getenv('WORDPRESS_DB_NAME') );

/** MySQL database username */
define( 'DB_USER', getenv('WORDPRESS_DB_USER') );

/** MySQL database password */
define( 'DB_PASSWORD', getenv('WORDPRESS_DB_PASSWORD') );

/** MySQL hostname */
define( 'DB_HOST', getenv('WORDPRESS_DB_HOST') );

For key and salt, you need to update wp-config.php with this value,

define('AUTH_KEY',         getenv('WORDPRESS_AUTH_KEY'));
define('SECURE_AUTH_KEY',  getenv('WORDPRESS_SECURE_AUTH_KEY'));
define('LOGGED_IN_KEY',    getenv('WORDPRESS_LOGGED_ID_KEY'));
define('NONCE_KEY',        getenv('WORDPRESS_NONCE_KEY'));
define('AUTH_SALT',        getenv('WORDPRESS_AUTH_SALT'));
define('SECURE_AUTH_SALT', getenv('WORDPRESS_SECURE_AUTH_SALT'));
define('LOGGED_IN_SALT',   getenv('WORDPRESS_LOGGED_IN_SALT'));
define('NONCE_SALT',       getenv('WORDPRESS_NONCE_SALT'));

Due to limitation from generating yaml value on Openshift, you might need to generate key and salt from this link when you deploy new Wordpress application.

So I use Persistent Volume on uploads folder only because this folder will be the only folder needs persistent storage. Create new constant value for Wordpress.

define('UPLOADS', 'pv-uploads')

And please make sure that the value is the same with this line. Container root folder is /opt/app-root/src, so you can change the folder name if you want.

If you need to deploy latest version of Wordpress, please update Build Config to use latest PHP version(read this requirements).
