Pokemon Showdown Architecture

[JTrenerry]

I am a software engineering student from Australia, and I currently have an assessment to do a case study on an open source project and examine its architecture. I choose showdown mainly because I have sunk many hours into it and love the product. Anyway, I was wondering if you could lend a hand? I have seen the .md files and read up on how the system works as a whole but have not seen much about the containerization of the code. So...
Do you use containers in a traditional sense (i.e. docker)?
If so, is it just the Game Server, Login Server and Client or....?
May have more questions depending on the response.
Also will be willing to slave away and do some open source work for your time haha
