How do I edit my "/containers/app.yml file" from the root@digitialoceandropletname ssh workspace?

You can use one of the templates from the templates folder. For example if you would like to run a stand alone server just use the standalone.yml file.

Example:

cp /var/discourse/samples/standalone.yml /var/discourse/containers/app.yml

In there you can make the necessary changes.
