Ok.

So:

  • This guide assumes you already have Discourse working : Ok so how is it possible. Because I can’t have discourse working because I already have an apache server running. When I try to install it, I can’t because the answer is something like: Your port 80 is already occupied, you can’t install it. => So, no my Discourse is not already working, I can’t install it.
  • Then, I want to use a docker container, in order NOT to install too many extra things on my production server. I don’t want to install an extra nginx server on my server
  • Finally: why would you answer me like that and who do you think you are ?

I never said they were careless nor anything, I am happy with their work, I am sad that it is not usable for me.
