🐳 Slim rootless Docker WordPress image with extras

rootless WordPress Docker Container

This Dockerfile installs WordPress 6.x, along with the latest wp-cli (used to download the WordPress as well), supervisor, nginx 1.24, and PHP-FPM 8.1 (on-demand PM) on Alpine Linux. It's designed as a rootless image, for heavy-load production sites and is currently being used in multiple environments without any issues.

The wp-config.php file included in this container is configured to use environmental variables, making management much easier. The nginx configuration has also been heavily tweaked and optimized. Additionally, the container runs a system cron instead of WP cron, as the latter is not very reliable.

Also, it has a script managed by supervisor process which copies all data automatically from /data and put into /usr/src/wordpress if you want to add files to the root folder, like robots.txt.

The current image size is around 80 MB, and the goal of this project is to make it even smaller.
