Okay. So I have now have a working discourse on a single machine. I have two other machines. The docker guest /shared volume is pointed to an NFS directory to allow all machines to access the uploads (esp. logos, etc).
I have copied the docker images to the machines 2 and 3 (docker save -o app-image local_discourse/app and then docker load -i app-image.
I was under the impression that a simple ./launcher start app would work, but it attempts to check containers/app.yml.
Will I run into problems if I allow the app.yml to be checked (and changes made) to the DB from machine 2 and 3?
Is there a better way to have three machines running a single setup?
