How to setup WordPress on Synology Docker

WordPress is the easiest blogging platform to host, so why not selfhost and use your own domain without paying extra for that feature?
Synology has an existing package for WordPress, should you use that? Or what if you have more than 1 webpage to host? You might even consider using the new mulit-site feature on WordPress.
Otherwise, here's how you can set it up on Synology Docker.

Prerequisites

1. Go to Package Center and install Docker
2. Go to File stations and navigate to Docker folder
3. Create two folders, wp-app and wp-db
4. Open Docker on Synology and select Registry tab
5. Search for WordPress and MySQL, download both with latest tag
   
6. Buy me a drink on Ko-fi :)

Create MySQL Container

1. Go to Container tab and Create a Container:
   1. Select Image: mysql
   2. Network: bridge
   3. Container Name: wp-db
2. Go to Advanced Settings
3. Add the following Enviroment variables:
   1. MYSQL_ROOT_PASSWORD = mysqlrootpassword
   2. MYSQL_DATABASE = wp
   3. MYSQL_USER = wpuser

4. Review, click Save, then Next
   
5. Leave the Port settings as default, click Next
6. Click Add Folder, navigate to the wp-db folder

Before you continue, be sure to check that the DB is ready. This should take ~5 mins.
