I am trying to find a default app.yml file to put into my containers folder so I can edit it as per here.
For now, when I try to run set up, I get this message.
Port 80 appears to already be in use.
If you are trying to run Discourse simultaneously with another web
server like Apache or nginx, you will need to bind to a different port
See https://meta.discourse.org/t/17247
If you are reconfiguring an already-configured Discourse, use
./launcher stop app
to stop Discourse before you reconfigure it and try again.
I have a ghost blog already taking up port 80 and 443. Just need a default yml file so I can run the installer then work with nginx.
