Docker Image with the latest WordPress version on top of NGINX and PHP7.2-FPM
Overview
This Docker image derives from the nginx-php7.2 image and installs the latest version of Wordpress that is available on GitHub.
For Users
The Initial Startup
The container keeps the entire WordPress installation at /var/www/html. Initially there is no configuration file
wp-config.php that contains the settings for the database and security keys. The startup script sets everything
up for you, so you don't have to use the WordPress setup wizzard. The startup script copies the sample configuration
file wp-config-sample.php shipped with the WordPress installation to wp-config.php and applies the desired settings
specified using environment variables below. At least WORDPRESS_DB_HOST, WORDPRESS_DB_USER, WORDPRESS_DB_PASSWORD
are required when running the container the first time.
If you want to persist your WordPress installation, installed addons and uploaded content across container restarts,
you should create a named volume and mount it at /var/www/html in the container. Otherwise Docker will delete the
container at shutdown including all the addons and additional content!
