[ELI5] What is a reverse proxy exactly and how do I use it to run several dockerized services on one machine? - eviltoast

So, I have some idea on what a reverse proxy does and will be using nginx (with the neat proxy manager UI) for my setup.

However, I’m not completely clear what exactly I want it to do and how I cn use it to run different services on one machine. I’m especially unclear on the ports configuration … tutorials will say things like “change the listening port to xxx for that service and to port yyy for the other service”

How does this work, which ports can I use and how do I need to configure the respective services?

EDIT: thanks everybody, your replies did help me a lot! I have my basic setup now up and running using portainer + nginx + fail2ban.

    Yeah, but you have to admit that children wouldn’t ask you what a reverse proxy is. I tried my best to write short, omitting details and in a simple language.
