No matter if we follow the exact documentation, again and again, we get this message every time we try to launch. Any help?
root@iLoveJesusChrist:/var/discourse# ./launcher start app
starting up existing container
This means you already have a webserver running on port 80 on your host machine.
Since Discourse is running in a Docker container (think: virtual machine on your server) it attempts to redirect all traffic arriving on port 80 to inside the container. So if there is already a webserver present on the host, it cannot use that port. You’d have to set up a reverse proxy on your main webserver or uninstall it and only use Discourse’s webserver in the container.

Yes, see this tutorial I put up finally having 100% success.
