I want to setup a forum called Discourse (Install Instructions) under the subdomain forum (forum.example.com)
It needs to be in a Docker container
It will be accessing the outside world as it is a forum application
I would like to use Certbot for Ubuntu 16.04 running apache with 2 domain names already there. (example.com, test.co.uk)
If I am running Let'sEncrypt for the first time on the VPS, will it show forum.example.com or just the 2 domains for the 2 sites?
