Centminmod + discourse

Installation
1

Hello.
I would love to try out the discourse platform on my centminmod LEMP stack ( https://centminmod.com/ )

I have sucessfully managed to installed Docker

docker -v
Docker version 20.10.17, build 100c701

I have followed the guide for install ( https://github.com/discourse/discourse/blob/main/docs/INSTALL-cloud.md) with a few minor tweaks - I dont have a cloud server per se. Its my managed instance.

I also had to edit my /containers/app.yml manually.

Once I have done this I get no errors when rebuilding the app via ./launcher rebuild app

However , I cannot connect to the docker instance either. It hits the landing page of my virtual host.

What do I need to do so that I can reverse proxy the nginx config to the docker? Or has anyone written a guide in installing discourse on centmindmod?

Thanks!

Andy

I guess this would be closest to what you are looking for Running other websites on the same machine as Discourse .

I have managed to get a working discourse install.

Install docker - not covered here
Install discourse -

git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse

Config app.yaml in /var/discource/containers

adjust app.yml to remove port 80+443
