Traefik is a good idea for other reasons, but there's no problem with using Docker to directly expose ports. You just need to ensure that you're only exposing the *right* ports, and aren't just blindly opening everything up to the world. By default nothing is exposed to the world. You do not need to expose your Redis server's port to anything.
