Wow, that was a mouthful. But yeah, that's what this repo does.
To get started, after you clone this repo, run docker-compose up -d and then visit http://localhost/.
If you are running this on a production server, you'll want to tweak the server name in
the HTTPS-Portal section of docker-compose.yml accordingly.
This repo is supporting material for the blog post at https://wp.dmuth.org/wordpress-5-in-docker-with-nginx-and-letsencrypt/
