Discourse requires ports 80 and 443. It cannot be run on a nonstandard port.

You will need to disable or remove Apache to use `./discourse-setup`.

If you want a reverse proxy in front, you can see [How to set up Discourse on a server with existing Apache sites](https://meta.discourse.org/t/how-to-set-up-discourse-on-a-server-with-existing-apache-sites/30013), but it requires a pretty good understanding of Apache and what reverse proxies are (and maybe English!). Oh, or the URL in the message that you include above.

You can copy `samples/standalone.yml` to `containers/app.yml`.

I have a German last name but speak no German outside of a couple dozen words all having to do with beer.
