Is Docker image discourse/discourse considered safe and production-ready?

I almost got it to work, but the mail sending wasn’t working.
I suppose it was because I have caddy as a reverse proxy.

Unless you’re somehow having Caddy proxy your outgoing email, I don’t think it’s related.

I suppose I have to make it use a socketed example, but I don’t know how to modify the app.yml inside the docker-compose discourse config.

You don’t have to make it socketed, you can just refer to the docker name and/or IP. Discourse working with jwilder /nginx proxy & acme-companion - #7 by Steve_Emerson talks about using the socketed template and a bunch of other stuff.
