After endless hours of diving into IT infrastructure topics like docker, networks, database setup and nginx including ssl certificates i finally got it to work. Still open questions but the first version is running smoothly.

Something something dark side…
This is just some sample content… to check whether image upload and this stupid stuff works… But i guess nginx config and the wordpress apache webserver still need some tweaking before everything is working correctly.. Näh I definitely don’t like editing some stuff that is in a container. I guess I have to switch to custom images and write my own config files and templates to make it easier to spawn new containers
