When I run the app as a package, app functions alright - connection to the database is established. As a result, we can write self-contained integration tests that depend on external resources. Stop Docker from (blindly) assigning IP addresses when we specify the -b=BRIDGE flag. You therefore need to listen on the external IP inside the container, and the easiest way to do that is by listening on all interfaces: 0.
