Nginx as Reverse Proxy for Docker Containers

My setup for the docker env. is the same as described on my DokuWiki Docker Container Portable, even though this should have almost zero effect even if the system is different (yay, docker!).

I will be using a Nginx Server as a Reverse Proxy, so that a) I can host multiple containers which need to be available in the same ports, b) I don't have to access the containers by memorizing ports therefore being able to use carlossousa.tech/wiki or wiki.carlossousa.tech instead of the port and c) easy expandability for new services / containers.
