We say this in our install guide discourse/docs/INSTALL.md at main · discourse/discourse · GitHub , but it seems likely you missed it:
The only officially supported installs of Discourse are Docker based. You must have SSH access to a 64-bit Linux server with Docker support. We regret that we cannot support any other methods of installation including cpanel, plesk, webmin, etc.
You’re coming in very hot here, so you’re getting the same energy you’re giving. Also note that just because your post was flagged doesn’t mean the staff will act on the flag, there are hundreds of people that can flag posts here and they’re not always acted on.
Unfortunately the answer to your question is still the same either way — there are so many hours in the day, so we only focus on supporting installs using Docker.
