The app in question is at https://github.com/jhsu802701/railn-20200316-215223-398
. Note that config/environments/development.rb is configured for MailCatcher.
I've been able to use MailCatcher without docker-compose, but I can't quite figure out how to get it to work in a Rails app that revolves around docker-compose.
One solution I tried is to add the 1080:1080 port assignments to the web section of docker-compose.yml, but the MailCatcher interface doesn't appear at http://localhost:1080/
Another solution I've tried is to add a mailcatcher section under services to make use of a Docker image dedicated to MailCatcher. While the MailCatcher interface does appear, the email messages I expect when I try to sign up in my local setup do not materialize.
Exactly what am I missing?
