[grantcodes][Zegnat] might be a bit late on your docker compose issues, but 1, you reference "db" as a dependency but in your example but it's actually called "database" in your version
[grantcodes]2. It works if you change versions of your dependencies, I just changed it to use the default versions of the images and it works. eg "image: mariadb" & "image: wordpress"
ZegnatThanks [grantcodes]! Seems weird that PHP 8 would change the actual flow of the code. Ie. that PHP 7 does not try to do the database call. But I will try and see what happens if I only lower the PHP version
[grantcodes]Yeah, I've not been following very closely to be honest. I'm sure wp core should run fine with php 8, but maybe some setup script in the docker? 🤷
