...it looks like you might have clarified, in a comment on an answer, that the database is on a different machine? Broadly, the setup you've shown here should work (use the database's DNS name or IP address as normal). A [mcve] including the actual error message would help clarify what's going on; definitely clarify if the database isn't on the same machine, since that's the case people frequently ask about. – David Maze Jan 05 '21 at 11:36

You should add
network_mode: host
to my_app, and use localhost

Host networking generally disables Docker's networking stack, and things like inter-container communication won't work well. I'd use one of the other solutions described in [From inside of a Docker container, how do I connect to the localhost of the machine?](https://stackoverflow.com/questions/24319662/from-inside-of-a-docker-container-how-do-i-connect-to-the-localhost-of-the-mach). – David Maze Jan 05 '21 at 11:34
