Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Container images.
WordPress is an online, open source website creation tool written in PHP. But in non-geek speak, it's probably the easiest and most powerful blogging and website content management system (or CMS) in existence today.
- Minimal size only, minimal layers
- Memory usage is minimal on a simple install.

Make sure you create the folder on the host before starting the container and obtain the correct permissions.
mkdir -p /data/{domain}/html
docker run -e VIRTUAL_HOST={domain}.com,www.{domain}.com -v /data/{domain}/html:/usr/html -p 80:80 yobasystems/alpine-php-wordpress
E.G
mkdir -p /data/yobasystems/html
docker run -e VIRTUAL_HOST=yobasystems.co.uk,www.yobasystems.co.uk -v /data/yobasystems/html:/usr/html -p 80:80 yobasystems/alpine-php-wordpress

This image now includes WP-CLI wpcli.org baked in... Its best to su nginx before executing anything or else you can potentially compromise your host.
docker exec -it <container_name> bash
su nginx
cd /usr/html
wp-cli core download --locale=en_GB
Edit the wp-config.php file and include the line;
define('WP_REDIS_HOST', 'redis');
The next thing is to install the plugin Redis Object Cache
If using SSL and running behind a proxy like HAproxy then the following needs to be added to the wp-config.php file (to stop infinite redirect);
define('FORCE_SSL_ADMIN', true);
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';
