Is it possible?
Are you planning to run more than one instance of Discourse? If not then this is probably not the how-to you’re looking for.
What you want is very possible and can be achieved in different ways. Since you’ll already be using Docker for Discourse, you’ll probably want to use Docker for the rest as well. So just use the default WordPress image for your WP and find a similarly suitable image for your PHP app.
thank you solo much!
