Pop your theme in here, whack in an SQL dump, bobs yr uncle. This is just for dev on a WP site, not for production.
Create an .env file in the root with the following:
WORDPRESS_DB_PASSWORD=xxx
WP_ADMIN_USER=xxx@exampkle.com
WP_ADMIN_USER_PASS_HASH=$1.xxxx.xxx.xx
MYSQL_ROOT_PWD=xXxXxXxX
Generate the hash, dont just send a password over.
Put your existing Wordpress SQL in the "seed" folder, as either an .sql or tar.gz file - this will be added to the database. You should set your root URLs as '/'
Put them within the correctly named subfolders in the 'theme' folder
Install docker compose, and run docker-compose from the root. Visit the IP given by the dump in your browser.
Wordpress may require you go to /wp-admin and upgrade the database.
