Wordpress
This instance has a long history, as I've migrated my blog several times. As a result of previously not keeping records, I've lost some of the history of how it got here.
Ultimately, I had to modify the docker-compose I'd made for Pressbooks to make this work (originally from here).
I briefly tried the version from awesome-docker-compose, but it doesn't support the ability to make basic edits to a Wordpress install, yikes!
(It also used a bad method for setting the database root password. D:)
