The goal of the Docker Flow Proxy project is to provide an easy way to reconfigure proxy every time a new service is deployed, or when a service is scaled. It does not try to "reinvent the wheel", but to leverage the existing leaders and combine them through an easy to use integration. It uses HAProxy as a proxy and adds custom logic that allows on-demand reconfiguration.
