Proper deployment with nginx etc

[interrogator]

We need a proper deployment of the site, handling multiple user sessions and so on. Some of the code is already there for this, but it needs to actually be put on a server and run/maintained. Suggested best practices for this are welcome @l0rb

I'm looking into this. My plan is to make the docker-version use nginx with uwsgi, and when that works it can either be deployed using docker (preferred) or using the dockerfile as a guide how to set the thing up.
