We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Modify docker configuration to work on OSX
Docker for Mac does not properly support the `network_mode: host` option for containers. In order to run the system on OSX, it will be necessary to network the containers using a bridged network:

> By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name."

Rather than accessing other containers via a port on localhost, containers will  access each other using the instance name as the hostname. Port 80 will then be exposed from the nginx container to the host.
