By default, the deployed docker container running your app's web process will bind to the internal docker network interface (i.e. `docker inspect --format '{{ .NetworkSettings.IPAddress }}' $CONTAINER_ID`). This behavior can be modified per app by disabling the proxy (i.e. `dokku proxy:disable <app>`). In this case, the container will bind to an external interface (i.e. 0.0.0.0) and your app container will be directly accessible by other hosts on your network.
