Docker Container, redirect?

Cool, thanks for your fast answer! In the meantime I stumbled upon this thread, with some more pointers on how to move forward. However, I’m not really used to work with docker and specifically redirect urls & ports, so on that part I hope the author is willing to write a short summary of steps to take… I realize the open source way of things is ‘learning by doing’, so I will also try to get up speed with the extra information provided there.
